Answer:
D
Step-by-step explanation:
in the question the scale factor is 4 so that means it is a dilation (getting larger) because the scale factor is >1
1/3 (3y - 6) = 8
distribute: y - 2 = 8
add 2 to both sides: y = 10

Answer:
Faith made = x = 24 cookies
Trinity made = y = 64 cookies
Step-by-step explanation:
Faith and Trinity are making cookies for Valentines day. Together they make a total of 88 cookies. How many cookies did each girl make?
Let the number of cookies
Faith made = x
Trinity made = y
x + y = 88
Trinity makes 40 cookies more than Faith.
y = x + 40
We substitute
x + y = 88
x + x + 40 = 88
2x + 40 = 88
2x = 88 - 40
2x = 48
x = 48/2
x = 24 cookies
y = x + 40
y = 24 + 40
y = 64 cookies
Therefore:
Faith made = x = 24 cookies
Trinity made = y = 64 cookies
She can buy 8 games and have $120 left in the bank
