If the graph of y=x^2 is compressed by a factor of 3 in the y-direction and then shifted 4 units down, the resulting graph would have an equation of 1) y=1/3x^2-4
2) y=-3x^2-4
3) y=-4x^2-3
4) y=-1/3x^2+4

answer: 20

step-by-step explanation:

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
