Find the equation of the line that
is parallel to y = 4x + 1 and
contains the point (1, 1).
y = [? ]X + [ ]
The equation of a line is:
[tex] \displaystyle \large{y - y_1 = m(x - x_1)}[/tex]
Since the line has to be parallel to line y = 4x+1. Hence, m = 4.
[tex] \displaystyle \large{y - y_1 = 4(x - x_1)}[/tex]
Given point is (1,1). Let this be the following:
[tex] \displaystyle \large{(x_1,y_1) = (1,1)}[/tex]
Substitute the point in.
[tex] \displaystyle \large{y - 1 = 4(x - 1)}[/tex]
Convert the equation in a slope-intercept form or function form.
First, distribute 4 in the expression.
[tex] \displaystyle \large{y - 1 = 4x - 4}[/tex]
Add 1 on both sides.
[tex] \displaystyle \large{y - 1 + 1 = 4x - 4 + 1} \\ \displaystyle \large{y = 4x - 3}[/tex]
Hence, the line that is parallel to y = 4x+1 and passes through (1,1) is y = 4x-3

. Each side of this ice cube measures 3.3 millimetres. What is the volume of this ice cube?
The volume of the ice cube is 35.937 mm^3
We know that for a cube of side length L, the volume is defined as:
V = L^3
Here, we do know that each side of our ice cube measures 3.3 mm, so we have:
L = 3.3mm
Then the volume of the cube is just:
V = (3.3 mm)^3 = 35.937 mm^3
We can conclude that the volume of the ice cube is 35.937 mm^3

Answer: sqrt(x+1)+4
This is the same as writing [tex]\sqrt{x+1}+4[/tex]
The +4 is not under the square root
==========================================================
Explanation:
g(x) is the same as y, since they're both outputs of a function
So we have the starting equation y = (x-4)^2 - 1
Swap x and y and solve for y to get the inverse.
y = (x-4)^2 - 1
x = (y-4)^2 - 1
x+1 = (y-4)^2
(y-4)^2 = x+1
y-4 = sqrt(x+1) ... see note below
y = sqrt(x+1)+4
Note: Recall that [tex]x \ge 4[/tex] and we swapped x and y. This ultimately means [tex]y \ge 4[/tex] and this only occurs if we picked the positive version of the square root (ignoring the negative version).

C)
One is given the following equation
[tex]\frac{z+1}{x-2y}-\frac{2z-3}{2x-4y}+\frac{z}{3x-6y}[/tex]
In order to simplify fractions, one must convert the fractions to a common denominator. The common denominator is the least common multiple between the given denominators. Please note that the denominator is the number under the fraction bar of a fraction. In this case, the least common multiple of the denominators is ([tex]6x-12y[/tex]). Multiply the numerator and denominator of each fraction by the respective value in order to convert the fraction's denominator to the least common multiple,
[tex]\frac{z+1}{x-2y}-\frac{2z-3}{2x-4y}+\frac{z}{3x-6y}[/tex]
[tex]\frac{z+1}{x-2y}*\frac{6}{6}-\frac{2z-3}{2x-4y}*\frac{3}{3}+\frac{z}{3x-6y}*\frac{2}{2}[/tex]

E)
In this case, one is given the problem that is as follows:
[tex]\frac{2}{3d+1}-\frac{1}{5d+3}[/tex]
Use a similar strategy to solve this problem as used in part (c). Please note that in this case, the least common multiple of the two denominators is the product of the two denominators. In other words, the following value: ([tex](3d+1)(5d+3)[/tex])
[tex]\frac{2}{3d+1}-\frac{1}{5d+3}[/tex]
[tex]\frac{2}{3d+1}*\frac{5d+3}{5d+3}-\frac{1}{5d+3}*\frac{3d+1}{3d+1}[/tex]

The final problem one is given is the following:
[tex]\frac{3a}{2a-3b}-\frac{a+b}{6b-4a}[/tex]
For this problem, one can use the same strategy to solve it as used in parts (c) and (e). The least common multiple of the two denominators is ([tex]6b-4a[/tex]). Multiply the first fraction by a certain value to attain this denomaintor,
[tex]\frac{3a}{2a-3b}-\frac{a+b}{6b-4a}[/tex]
[tex]\frac{3a}{2a-3b}*\frac{-2}{-2}-\frac{a+b}{6b-4a}[/tex]

A rectangular mural has dimensions of (x + 10) and (x + 3) feet. If the area of the mural is 60
square feet, what are its length and width?
Answer:
Dimensions are 12 , 5
Step-by-step explanation:
Area of rectangular mural = length * width
length * width = 60 square feet
(x + 10)(x + 3) = 60
Use FOIL method
x*x + x*3 + 10*x + 10*3 = 60
x² + 3x + 10x + 30 = 60 {Combine like terms}
x² + 13x + 30 - 60 = 0
x² + 13x - 30 = 0
Sum = 13
Product = -30
Factors = 15 , -2 (15+ (-2) = 13 ; 15*(-2) = -30)
x² + 15x - 2x - 30 =0 {Rewrite middle terms}
x(x + 15) - 2(x + 15) = 0
(x + 15)(x - 2) =0
x - 2 = 0 {Ignore (x +15) as dimensions wont have a negative value}
x = 2
x + 10 = 2 + 10 = 12
x + 3 = 2 + 3 = 5
Dimensions are 12 , 5

Answer:
9
Step-by-step explanation:
This is a right triangle. We can use the Pythagorean theorem to determine the missing side.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 12 ^2 = 15^2
a^2 +144 =225
a^2 = 225-144
a^2 = 81
Taking the square root of each side
a = 9
Answer:
9
Step-by-step explanation:
Because the triangle is a right triangle we can use the Pythagorean Theorem to solve for the missing side.
Pythagorean Theorem: a² + b² = c²
where
a = short leg
b = long leg
c = hypotenuse ( longest side )
we are given the hypotenuse and long leg and need to find the short leg
given hypotenuse (c) = 15
given long leg (b) = 12
short leg (a) = ?
to find the short leg plug in the known values into the Pythagorean Theorem and solve for a
a² + b² = c²
b = 12 and c = 15
a² + 12² = 15²
solve for a
a² + 12² = 15²
apply exponents
a² + 144 = 225
subtract 144 from both sides
a² = 81
take the square root of both sides
√a² = √81
a = 9

Answer:
A. 1.5 s; 42 ft
Step-by-step explanation:
1.5 sec and will reach a height of 42 feet
that is the vertex
for y=ax^2+bx+c
the x value of teh vertex is
the y value is found by subsituting the x value of the vertex for x
so
h=-16t^2+48t+6
a=-16
b=48
c=6
x value of vertex is
subsituting it for x we get
it reaches the max height of 42ft at 1.5 seconds

You work at McDonalds making $9 per hour, this week you are scheduled to work
4:30pm - 10pm Wednesday - Saturday. How much will your gross pay be for the WEEK?
(you are on the clock the entire shift)
Answer:
$198
Step-by-step explanation:
Basically what I did was how long is 4:30 - 10:00 pm (5 hours and 30 minutes)
and multiplied that by your hourly rate. So 5 × 9 = 45, 9 ÷ 2 = 4.5, 45 + 4.5 = 49.5, 49.5 × 4 = 198. And since you don't clock out and this is your gross payment then that is the final answer

Answer:
1159
Step-by-step explanation:
She wants to read 1000 pages per week for five weeks.
So in total she wants to read 1000 * 5 = 5000 pages.
The first three weeks she read 894 pages per week.
So during the first three weeks she read a total of 894 * 3 = 2682 pages.
We want to find how many pages she must read per week for the last two weeks to reach her goal.
Goal: 5000 pages
Pages read so far: 2682
Weeks remaining: 2
To find how many pages she must read for the last two weeks we simply subtract the number of pages she read during the first 3 weeks (2682 ) by her goal ( 5000 )
5000 - 2682 = 2318
So she must read 2318 pages during the last 2 weeks.
If we want to find the amount of pages she must read per week during the last 2 weeks to reach her goal, we simply divide the amount of pages she must read during the last few weeks to reach her goal ( 2318 ) by the number of remaining weeks ( 2 )
2318 / 2 = 1159
So for the last two weeks she must average 1159 pages per week.
Answer:
1159 pages
Step-by-step explanation:
According to Briana's goal,
Pages to be read per week = 1000 pages
Number of weeks = 5
So, pages to be read in 5 weeks
= 5×1000 pages
= 5000 pages
But in reality,
Pages read in each first 3 weeks = 894 pages
So, total pages read in all first 3 weeks
= 3×894 pages
= 2682
Pages remained to be read to complete the goal
= Pages to be read in 5 weeks according to her goal - Pages actually read in all first 3 weeks
= 5000 pages - 2682 pages
= 2318 pages
So, pages to be read in each last 2 weeks
= 2318 pages/2
= 1159 pages
So, Briana will have to need to average 1159 pages over the last two weeks to complete her goal.

I would like to know the value of b and c
Answer:
a = 3, b = 8, c = 14
Step-by-step explanation:
First, we can organize this, putting lower values first.
2, 3, 3, 5, 9, 9, 11, 12
a , b , c somewhere there
Given this information, one thing we can look at first is the mode. The mode is 3, so there must be more 3s than any other number. Currently, there are 2 3s and 2 9s, so there must be at least one more 3 and no more 9s to make that true. Therefore, a, b, or c is 3. Therefore, we have
2, 3, 3, 3, 5, 9, 9, 11, 12
2 of a, b, c somewhere in there
Next, the median is 8. In our current state, the median is 5. There are 9 numbers, with 11 total including the 2 remaining values. Because there will be an odd amount of values, the median must be a number on the list. Therefore, our list is
2, 3, 3, 3, 5, 8, 9, 9, 11, 12
1 of a, b, c somewhere in there
There are 4 numbers above the median and 5 numbers below right now. To balance this out, there must be another number above the median. As a consequence, the remaining value must be greater than 8.
Finally, we know that the range is 12, so maximum - minimum = 12. Because the remaining number must be greater than 8, the minimum number is 2, no matter what. Therefore,
maximum - 2 = 12
add 2 to both sides to isolate maximum
maximum = 14
There is no 14 currently on the list, so the remaining value must be 14.
Our a, b, and c are as follows, in order from smallest to largest:
3, 8, 14

This is a simple test of your knowledge about this sort of problem. When you get 2 parallel lines intersected the way you see in the picture, the lower right angle of the first intersection is equal to the upper left angle of the first line as well as the upper left and lower right angles of the second line so with that knowledge you can immediately identify that since the question gives you the measure of an angle equal to the angle you need to identify; you don't even need to do any math to find the answer for this question.

Answer: Pretty sure that it's y=-5/3x+8
Step-by-step explanation: Since the slope-intercept form is y=mx+b with b as the y-intercept and m as the slope. b would be 8 since that's where the line intercepts the y-axis and the slope is -5/3 (negative bc the line is slanted down)
Answer:
y = - [tex]\frac{8}{5}[/tex] x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 8) and (x₂, y₂ ) = (5, 0 ) ← 2 points on the line
m = [tex]\frac{0-8}{5-0}[/tex] = [tex]\frac{-8}{5}[/tex] = - [tex]\frac{8}{5}[/tex]
The line crosses the y- axis at (0, 8 ) ⇒ c = 8
y = - [tex]\frac{8}{5}[/tex] x + 8 ← equation of line
