You multiply both sides by 9 first so you have -45=y-7. then add 7 to both sides to get y=-38
Answer:
(1, 0)
Step-by-step explanation:
360º is a full circle and is the same as 0º, so this is on the x-axis.

(1, 0)
The correct answer is 14.2 lb which is choice D.
Let:
F = minimum force required to prevent ball from rolling down the ramp
The formula will be:
F = w * sin theta
F = w * sin (39 degrees)
F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
