<span>Given that f(x) = 2x + 5 and g(x) = x − 7
</span>f(g(x)) = 2(x − 7) + 5
f(g(x)) = 2x - 14 + 5
f(g(x)) = 2x - 9
when x = −3 , f(g(-3)) = 2(-3) - 9 = - 6 - 9 = -15

Step-by-step explanation:
Givens
- Linda 35 mph
- Martin 60 mph
- distance travelled = 855 miles
Formula
Linda's speed * t + martin's speed * t = 855
s1 * t + s2 *t = 855
Solution
35*t + 60*t = 855t Combine the left
95t = 855 Divide both sides by 95
95t/95 = 855/95
t = 9
Answer
They will meet in 9 hours.
