r = 29.82
Step-by-step explanation:
We have the equation r/7.1 = 4.2 and are asked to solve for r.
To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:
r/7.1 = 4.2
r = 29.82

Answer:
D. y + 7 = -3(x - 5)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
⇒ y - (-7) = -3(x - 5)
⇒ y + 7 = -3(x - 5)
