Consider this solution to a problem.

Problem: −4(6−y)+4=−4
Step 1: −24−4y+4=−4
Step 2: −20−4y=−4
Step 3: −4y=16
Step 4: y=−4
In the first response box, enter the number of the step where the mistake is made.

step 1 because you cant get y by itself by subtracting 4 from 24 and 4 you need to subtract it from -4y and -4

Step-by-step explanation:

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
