Brandon deposited $250 into a checking account that does not earn interest. Each month he withdrew $10 and then deposited $45 into the account. Which type of function best models the amount of money that Brandon has in his account after x months? A. exponential function with a growth rate of $55 per month

B. linear function with a rate of change of $35 each month

C. linear function with a rate of change of $55 each month

D. exponential function with growth rate of $35 each month

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

4 times 8.

your answer is 96cm.

hope this .

just a girl thing, i think im cute when im not lol
