Identify the range of the function shown in the graph

-1\leq y\leq 1

Step-by-step explanation:

In order to find the range, you just need to look at the y values, or the y axis, of the graph. Wherever the top and bottom of the graph is the range. In other words, the top of the curve and the bottom of the curve help you determine the range.

The top is y=1, and the bottom is y=-1

With this information, you write it as if you were looking at a number line: left to right; negative to positive.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
