Which inequality is equivalent to this one?

y-8 < (with the line under it) -2

a. y-8+8 > (with the line under it) -2+8
b. y-8+8 < -2+8
c. y-8+2 < (with the line under it)-2+8
d. y-8+2 < (with the line under it)-2+2

D  y-8 +2 ≤ -2+2

Step-by-step explanation:

y-8 ≤ -2

Add 2 to each side

y-8 +2 ≤ -2+2

the graph top, left is y = 4x

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
