45 miles per hour is 3/4 mile per minute. Divide 4.8 by 0.75.
2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:

Answer:
r = 9
Answer: C) (1,4)
Step-by-step explanation:
<em>The intersection point is where f(x) = g(x)</em>
x³ + 3x = x² + 3
x³ - x² +3x - 3 = 0
- A. (0, 0) → x = 0 → (0)³ - (0)² +3(0) - 3 = -3 ≠ 0
- B. (0, 3) → x = 0 → (0)³ - (0)² +3(0) - 3 = -3 ≠ 0
- <u>C. (1, 4) → x = 1 → (1)³ - (1)² +3(1) - 3 = 0 + 0 = 0</u>
- D. (-1, 4) → x = -1 → (-1)³ - (-1)² +3(-1) - 3 = 0 - 3 - 3 = -6 ≠ 0
