Answer:

y=3x+1, or the second option

Step-by-step explanation:

We can see on the graph the line converges with the y-axis at (0, 1), so we can cross out the last two answers. Then we can also see that the slope is 3 on the graph and an equation that has x^2 must be a parabola. The answer is then narrowed down to the second option.

1. 4t + 3.5 =12.5
what is t equal to

2. 8m - 5.5 =10.1
what is m equal to

Answers

Step-by-step explanation:

This is the answer that you want

t=9/4

m=1.95

Answer:

t = 2.25 and m . 1.95

Step-by-step explanation:

4t + 3.5 = 12.5

to start, isolate the variable by subtracting 3.5 from both sides

4t = 9

then, divide both sides by 4 to find what t is equal to

t = 2.25

8m - 5.5 = 10.1

isolate the variable by adding 5.5 to both sides

8m = 15.6

then, divide both sides by 8 to find what m is equal to

m = 1.95
