20.4 is the exact circumference of the circle
Answer:
2640
Step-by-step explanation:
110mi/hr = Xmi/day
24hr = day
110mi x 24hr = 2640mi/day
F(x) = -5x + 3
f(-4) = -5(-4) + 3
f(-4) = 20 + 3
f(-4) = 23
D: Add 9 to both sides of the equation
This is because when the number is positive or negative, you use the inverse operation to solve.
