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 ;)

40 is the final : )

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
