Answer 1

Answer: Hi There!

What is the solution to the equation? 4y – 12 = –4 A. y = 11 B. y = 2 C. y = –4 D. y = –13

Answer:y=2

Answer 2

Answer: First simplify
4y+-12=-4
Reorder the terms:
-12+4y=-4
Move all terms containing "y" to the left, all other terms to the right.

Add 12 to each side of the equation:
-12 + 12 + 4y = -4 + 12

Combine like terms:
-12 + 12 = 0
0 + 4y = -4 + 12
4y = -4 + 12
Combine like terms:
-4 + 12 = 8
4y = 8
Divide each side by '4'.
y = 2

So your answer is B Y=2
hope this helped

Answers

Simply, the question wants you to write an equation for the points they gave you.

The points are:
(0,60)
(1,65)
(2,70)
(3,75)

The first thing we need to do is to find the slope.

$\sf{Slope =(y_2-y_1)/(x_2-x_1) =(65-60)/(1-0) =(5)/(1) =\boxed{\bf{5}}$

The slope is 5.

If we write an equation in the form of y = mx + b, where m is the slope, and b is the y-intercept, we would have so far:

y = 5x + b

Now, we need to find the y-intercept.
We are given the point (0,60)
That point lies on the y-axis, and therefore, 60 is the y-intercept.

Our final equation is y = 5x + 60.

Solve for x.
3x − 2(x + 3) = 5 − 2x

In 2007, the US population was 302 million people. In 2012, and 314 million. What was the rate of the population change per year?

Answers

The correct answer is:

2.4 million.

Explanation:

To find the rate of change, first we find the amount that the population grew in the time period:

314-302 = 12

Now we calculate the number of years:

2012-2007 = 5

Divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year.

314 - 302 =12 / 5 = 2.4,

the population grows 2.4 percent of people a year.

Tell whether the ratio form a proportion
14/21 =26/39

Answers

if the ratios form a proportion, the ratios will be equal. first we'll simplify the ratios:

14/21
divide top and bottom by 7
2/3

26/39
divide top and bottom by 13
2/3

ss you can see now, the ratios are indeed equal, so they do form a proportion
