Mark as brainleist part a and b explain

PART A:

Sue:

C= $660

H= 12 hours

Jon:

C= $440

H= 8 bours

PART B:

Tex can only get 8 hours of training because he only has $440, so what I did was I divided $660 and 12 hours together and got 55 which is how much Sue payed per hour and I did the same for Jon and his dog Tex. Really hope this helps you a lot!

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be

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.
