What is the value of h(−2) when h(x)=3x+1

h(-2) = -5

Step-by-step explanation:

Step 1: Define

h(x) = 3x + 1

h(-2) is x= -2

Step 2: Substitute and Evaluate

h(-2) = 3(-2) + 1

h(-2) = -6 + 1

h(-2) = -5

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
