Which of the following functions has a rate of change that stays the same?
A. y=-4x+10
B. Y=1/2x^2
C. y = 3^x
D. y=x^2+2

A

Step-by-step explanation:

it is the only one that is linear:

Linear means the slope stays the same, it can look like: y=#, y=#x, y=#.##x, y= #over#x. It always has the variable x, unless it is just one number. alos linear is a straight line

Exponential is a slope that always changes, it does not increase by the same amount every time, but it does have a pattern. They always have a #x^# that is what makes it exponential, an exponent.

I hope this all helps u

pls give a brainliest and a thx ;)

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.

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.
