Answer:
C(x) = 7x + 10
Step-by-step explanation:
If the delivery charge is $10 for any number of board feet ordered.
If the delivery charge is $10 for each board feet ordered, the function would
be C(x) = (7 + 10)x = 17x
780 (or c)
I think this is correct because 4 x 5 = 20 x 5 = 100 and 100 x 5 = 500
500 + 280 = ????
780
It would be 20% because if you take 100 times 1/5, which is the same as 100/5, you would get 20, which is 1/5.
D- It is an enlargement with a scale factor greater than 1.
From the pre-image to the image, the scale factor is 3.
27 I think or something close to that hope that helps
