Answer:
8.2×3=24.6 miles
Step-by-step explanation:
8.2 times 3= 24.6
You are running 8.2 miles per hour for 3 hours.
7 + 8(2r - 9)
mutiply the bracket by 8
(8)(2r)= 16r
(8)(-9)= -72
7+16r-72
7-72+16r ( rearranging)
answer:
-65+16r or 16r-65
(2,3)
4
Evaluate f(3) and g(2)
f(3) = 2(3) - 4 = 6 - 4 = 2
g(2) = - 3(2)² + 5(2) = - 3(4) + 10 = - 12 + 10 = - 2
Then
f(3) - g(2) = 2 - (- 2) = 2 + 2 = 4
