Which linear equation represents a line with a slope of 9/4 and a y-intercept of 0? plz help giving out brainliest
Answer:
y = 9/4x.
Step-by-step explanation:
According to slope-intercept form, y = mx + b where m is the slope and b is the y-intercept.
So, y = 9/4x + 0
y = 9/4x.
Hope this helps!
The required equation of the line is given as 9/4x with a slope of 9/4 and a y-intercept of 0.
Given that,
The linear equation represents a line with a slope of 9/4 and a y-intercept of 0 is to be determined.
What is the slope of the line?
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
here,
Standard equation of the line,
y = mx + c
Put , = 9/4 and c = 0
y = 9/4x + 0
y = 9/4x
Thus, the required equation of the line is given as 9/4x.

Write this equation in slope-intercept form. 5x - 6y = -6 *
Answer:
y = 5/6x +1
Step-by-step explanation:
5x - 6y = -6
We want the equation in the form
y = mx+b where m is the slope and b is the y intercept
Subtract 5x from each side
5x -5x - 6y =-5x -6
-6y = -5x -6
Divide each side -6
-6y/-6 = -5x/-6 -6/-6
y = 5/6x +1

Marly needs to score 586 points in order to pass a test. Every question is worth 4 points. She already has 58 points. How many more questions does she need in order to pass this test?
Answer:
89
Step-by-step explanation:
586 divide by 4 is 146.5 so then i rounded to make it 147 then subtracted the points she already had (58) which led me to 89
Answer:
132 questions
Step-by-step explanation:
First, let’s find how many more points she needs.
To find this, find the difference between the points she needs and the points she has.
points needed- points gained
She needs 586 points and already has 58 points.
586 points-58 points
528 points
Now, we need to find how many questions she needs to answer correctly.
She needs 528 points and every correct question is worth 4 points.
Therefore, we can divide 528 by 4 to find how many questions she must answer correctly.
528/4=132
132 questions
She must answer 132 questions correctly to pass the test.
Mapiya writes a series of novels. She earned \$75{,}000$75,000dollar sign, 75, comma, 000 for the first book, and her cumulative earnings double with each sequel that she writes.
Answer:
[tex]E(n)=75000 \times 2^n[/tex]
Complete question:
write a function that gives mapiyas cumulative earnings E(n), in dollars when she has written n sequel's
Step-by-step explanation:
According to the question, she earned $75000 for the first book.
Also,We are given that her cumulative earnings double with each sequel that she writes.
Assuming she has written n sequel's
Now since we are given that her cumulative earnings double with each sequel
So, her initial earning will be [tex]2^n[/tex] times
So, her earning will be : [tex]75000 \times 2^n[/tex]
Now we are given that cumulative earnings is denoted by E(n)
So, the function becomes :[tex]E(n)=75000 \times 2^n[/tex]
Hence a function that gives Mapiya's cumulative earnings E(n), in dollars when she has written n sequel's is [tex]E(n)=75000 \times 2^n[/tex]

product 48 and sum 14 what are the factors
Answer:
Step-by-step explanation:
Let's write a system.
Let's say that the variables are x and y.
xy=48
x+y=14
Solve for one of the variables, let's say, x.
x=14-y.
Now substitute x into the 1st equation.
(14-y)y=48
Simplify.
-y²+14y=48
Make it into a quadratic equation.
-y²+14y-48=0
Make sure y²'s coefficient is one. Divide everything by -1
y²-14y+48=0
Now factor!
What factors add up to 14 and multiply to 48.
6 and 8!
Since the 2nd term is negative, and the 3rd term is positive, the factors have to be negative.
y²-6y-8y+48=0
Group.
(y²-6y)+(-8y+48)=0
y(y-6)-8(y-6)=0
(y-8)(y-6)=0
y-8=0
y-6=0
y=8 y=6
now let's substitute each y value into y²-14y+48=0
8²-14(8)+48=0
64-112+48=0
0=0. so y=8 checks out!
6²-14(6)+48=0
36-84+48=0
0=0 so y=6 also checks out!
Choose one y value and solve for x, in each equation :
xy=48
x+y=14
8x=48
x+8=14
x=6
x=6
It checks out!
so the factors are
x=6 y=8.

Answer: D
Step-by-step explanation:
Distributive Property is when you want to apply to FOIL method when you are multiplying out the expression. You would have multiple number/terms to multiply out to. The only answer choice that shows this is D.
In D, you are distributing the 5 to 8 and -2. So, you are multiplying 5×8=40 and 5×-2=-10. Then you have 40-10.
A is just multiplying, 5 and 1/5.
B is just multiplying 5 and 1.
C is just Associative Property, changing the parenthesis.
D shows Distributive Property.
Answer:
The answer is DExplanation:
D is the answer because you need the 5 to be next to the number in parenthesis.C is the not the answer because when there is a minus sign with a number in front of the parenthesis, the numbers in the parenthesis will bave to be solved instead of distributed.
B is not the answer because there are not even parenthesis to empasise the distibution.
A is not the asnwer because the numbers are simply being canceled out into the number 1 with a fraction and a whole number.

the weights, in pounds, of the upper class men offensive line players for a college are shown below:
322, 290, 321, 326, 330, 315, 311, 292, 290
What is the average, or mean, weight of the upper-class men offensive players? provide your answer with 3 sig figs.
1) 311 pounds
2) 315 pounds
3) 290 pounds
4) 318 pounds
Answer:
311 pounds
Step-by-step explanation:
Here, we are to calculate the average weight of the upper-class men offensive players
To calculate this, we need to sum up all the weights and divide by their count
Mathematically, that would be;
Average weight = (322+290+321+326+330+315+311+292+290)/9 = 2,797/9 = 310.77778
Now this written in 3 significant figures would be 311 pounds
Answer:
311
Step-by-step explanation:
You add all of the numbers first (2797)
Then you divide by how many numbers there were (9)
You get 310.7778
Then you round with 3 sig figs.
That is 311

5(3a+b)−2(3a+b)
Answer:
9a + 3b
Step-by-step explanation:
Given
5(3a + b) - 2(3a + b) ← distribute both parenthesis
= 15a + 5b - 6a - 2b ← collect like terms

Answer:
a) Area of wall to be painted = 114 sq ft
b) Number of cans required = 2×5 = 10
c) Total cost of paint = $338.43
Step-by-step explanation:
Part a)We are asked to find the area of wall that needs to be painted.
we need to subtract the area of window from the area of wall.
We know that area of a rectangular shape is given by
Area = Width×Length
Area of whole wall = 8×15 = 120 sq ft
Area of window = 2×3 = 6 sq ft
Area of wall to be painted = 120 - 6 = 114 sq ft
Part b)1 can of paint will cover 25 sq ft of area.
So to cover the area of wall to be painted,
114/25 = 4.56
since number of cans cannot be in fraction so we would need 5 cans
Since two coats of paints are needed so
Number of cans required = 2×5 = 10
Part c)1 can of paint costs $29.95
We have total 10 cans
$29.95×10 = $299.5
There is also a 13% tax so the total cost is
$299.5×0.13 = $38.93
Total cost of paint = $299.5 + $38.93
Total cost of paint = $338.43
in this figure what is m 5?
Answer:
m<5 = 95 degrees
Step-by-step explanation:
Let's first find m<1
=> m<1 = 180-85
=> m<1 = 95 degrees
Since,
m<1 = m<5 (Corresponding angles)
So,
m<5 = 95 degrees
For the last 4.5 hours, the temperature has decreased at a rate of 2.8 Degrees Fahrenheit per hour. Which best represents the overall change in temperature over this time period?
Answer:
The overall change in temperature over the time period ∆T = -12.6°F
Step-by-step explanation:
Rate of change of temperature r = -2.8°F per hour
Time t = 4.5 hours
The overall change in temperature ∆T = Rate of change of temperature × time period
∆T = r × t
∆T = -2.8°F per hour × 4.5 hours
∆T = -12.6°F
The overall change in temperature over the time period is -12.6°F
Answer: -12.6

“Jackson buys a cherry snow cone on a hot day. What is the volume of “snow” he gets to eat? Use 3.14 for pi. Round you answer to the nearest tenth.”
Answer:
Correct option: Second one -> 141.3 cm3
Step-by-step explanation:
The volume of "snow" is the sum of the half sphere volume and the cone volume.
The volume of the half-sphere is given by the formula:
V = (2/3) * pi * radius^3
If the half sphere has a radius of 3 cm, we have that:
V1 = (2/3) * pi * 3^3 = 56.5 cm3
The volume of the cone is given by:
V = (1/3) * pi * radius^2 * height
If the radius is 3 cm and the height is 9 cm, we have:
V2 = (1/3) * pi * 3^2 * 9 = 84.8 cm3
So the final volume is:
V = V1 + V2 = 56.5 + 84.8 = 141.3 cm3
Correct option: Second one
