Answer:
Step-by-step explanation:
1. An equation is said to be linear if the variables have power not greater than 1.
Thus, the linear equations from the list are:
B. Y = [tex]\frac{2}{3}[/tex]x + 6
C. Y = |x| + 4
D .Y = 2x - 5
2. Comparing the equations with y = mx ± c, the constant rate of change for each linear equation are:
B. [tex]\frac{2}{3}[/tex]
C. 1
D. 2
3. The constant rate of change is the gradient (slope) of a linear equation. It describes the steepness of a line from the plot of points obtained from the linear equation.

What is the slope of a line that is perpendicular to the graphed line?
Answer:
The slope of the line perpendicular to the graphed line is 2.
Step-by-step explanation:
The Slope of a Line
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
The graphed line passes through two visible points (0,4) and (8,0). Thus, its slope is:
[tex]\displaystyle m=\frac{0-4}{8-0}[/tex]
[tex]\displaystyle m=\frac{-4}{8}[/tex]
Simplifying:
[tex]\displaystyle m=-\frac{1}{2}[/tex]
Two lines of slopes m1 and m2 are perpendicular is:
[tex]m_1.m_2=-1[/tex]
Suposse the given line has slope [tex]m_1=-\frac{1}{2}[/tex]. To find m2, we solve the above equation:
[tex]\displaystyle m_2=-\frac{1}{m_1}[/tex]
Substituting:
[tex]\displaystyle m_2=-\frac{1}{-\frac{1}{2}}[/tex]
Operating
[tex]m_2=2[/tex]
The slope of the line perpendicular to the graphed line is 2.
write 62/15 as a mixed number.
Answer:
4 & 2/15Step-by-step explanation:
Answer:
[tex]4\frac{2}{15}[/tex]
Step-by-step explanation:
A mixed number is a number that contains an integer with a proper fraction eg: [tex]1\frac{1}{2}[/tex]. The fraction that is given is improper and can be turned into a mixed number to simplify it.
First, we need to find how many times 15 goes into 62:
62÷15 = 4r2
This can then be written as the mixed fraction: [tex]4\frac{2}{15}[/tex].
I hope this is clear :)

Convert the following into slope-intercept form. 3x+4y=-16
Answer:
y = -3/4x -4
Step-by-step explanation:
3x+4y=-16
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
Subtract 3x from each side
3x -3x+4y=-3x-16
4y = -3x-16
Divide each side by 4
4y/4 = -3x/4 - 16/4
y = -3/4x -4
Answer:
y= -3/4x - 4
Step-by-step explanation:
3x+4y=-16
4y= -3x-16
y= -3/4x -4

Joe creates a new email account. In October he receives 120 emails and in November he receives 177 emails. Joe says the percent change from October to November
is calculated by taking the ratio of the difference between the number of emails received in November and October to the number of emails received in November
Therefore, he says, the percent change, rounded to the nearest whole percent is 32%. Is he correct?

9-(6x+1)=3x+8 please help me with this I don’t know how to solve it.
Answer: 0
Step-by-step explanation: You isolate the variable by dividing each side by factors that don't contain the variable.
Answer: x = 0
Step-by-step explanation:
9-(6x+1) = 3x + 8
9 - 6x -1 = 3x + 8
8 -6x = 3x + 8
+6x +6x
8 = 9x + 8
-8 -8
0 = 9x
/9 . /9
x =0
Joseph needs 345 cement blocks to build a wall 40 cm thick. He needs 205 cement blocks to build a wall 25 cm thick. Each block costs $0.75. How much more will the thicker wall cost?
9514 1404 393
Answer:
$105
Step-by-step explanation:
The thicker wall takes 345 -205 = 140 more blocks. Each of those costs $0.75, so the added blocks will cost ...
140 × $0.75 = $105
The thicker wall will cost $105 more.

A new video game is expected to sell 120 copies the first hour at a local game store. After that, the sales will follow the function s(x) = 15(x - 1) where x is the number of hours. What is the
function that shows total sales, including the first hour? (1 point)
s(x) = 15(x - 1) - 120
s(x) = 120x - 15
Os(x) = 120 + 15(x - 1)
Os(x) = 120 - 15(x - 1)
Answer:
X=104
Step-by-step:
Sorry IF my answer is wrong
Answer:
Os(x) = 120 + 15(x - 1)
Step-by-step explanation:
The total sales will be the sum of the constant 120 copies that were sold in the first hour and the sales in the subsequent hours, represented by the function s(x) = 15(x-1).
Thus, add 120 to the function s(x).

whats 100x100x100 idk wht it is
Answer:
100,000,0
Step-by-step explanation
To solve this problem you need to start with 100, since 100 has 2 zero's you want to add 2 zero's 2 times in a row, like this-- 100+00=10,000+00=100,000,0.
Thus your answer: 100,000,0
Solve the inequalities by graphing. Identify the graph that shows the following equations.

Select all the ordered pairs that make this statement true?
3x + 4y = 36
(3,-2)
(1,7)
(0,0)
(24,-9)
(0,9)
(4,6)
(-12,18)
Answer: (24,-9)
(0,9)
(4,6)
Step-by-step explanation:
3x + 4y = 36
Using (3,-2) will be:
= 3(3) + 4(-2)
= 9 - 8 = 1
Using (1,7) will be
= 3(1) + 4(7)
= 3 + 28 = 31
Using (0,0) equals to 0
Using (24,-9) will be:
= 3(24) +4( -9)
= 72 - 36 = 36
Using (0,9) will be:
= 3(0) + 4(9)
= 0 + 36 = 36
Using (4,6) will be:
3(4) + 4(6)
= 12 + 24
= 36
Using (-12,18) will be:
= 3(-12) + 4(-18)
= -36 - 72
= -108
The correct options are (24,-9), (0,9 and (4,6)

If a truck that is traveling at 15 mph speeds up to 45 mph in 10 seconds, what is the truck’s acceleration?
Answer:
3miles per hour^2
Step-by-step explanation:
given data
initial speed u= 15mph
final speed v=45mph
time taken t= 10 seconds
Step two:
Required
acceleration a=?
applying the first equation of motion
v=u+at
substitute we have
45=15+a*10
45=15+10a
make a subject of the formula
45-15=10a
30=10a
divide both sides by 10
a=30/10
a=3miles per hour^2
