For a translation of 4 units right, the graph will become -3(x-4). the 4 is negative to indicate that the translation is right.
For a vertical stretch of 4, the graph will become 4x-3(x-4)=-12(x-4).

With this information, g(x)=-12(x-4)

Find the equation of the line with a slope of 2/5 and containing the point (10,6).

Kipish [7]

Use the poin-slope form of the equation of a line:-

y - y1 = m(x - x1) (where m = slope and the point is (x1, y1))

Plugging in the given values:-

y - 6 = 2/5(x - 10)

multiplying through by 5:-

5y - 30 = 2(x - 10)

5y - 30 = 2x - 20

5y = 2x + 10

In standard form the equation is

2x - 5y = -10 (answer)

$AP =(0.16*\$3)+(0.32*\$5)+(0.52*\$10)\\AP=\$7.28$
