Answer:  For part A, the formula for the employee's pay is  <em><u>P</u></em>ay = hourly <em><u>r</u></em>ate times <em><u>h</u></em>ours .  P = r × h  The equation is P = 13h   To find how many hours are required to earn a given amount, fill in given values and solve for the missing variable .  7800 = 13h   h= 7800/13    600 hours needed.

For part B, the formula for this employee's pay is  <em><u>P</u></em>ay = <u><em>B</em></u>onus + hourly <em><u>r</u></em>ate times <em><u>h</u></em>ours .   P = b + rh

330 = 90 + r(24)    330 - 90 = 24r .  240 = 24r    240/24 = r . r = 10

The employee's pay rate is $10 per hour.

F(x) = 2x^2-7x-7<br> g(x) = x+1<br><br> Find f(g(x))
adell [148]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

f(x) = 2 {x}^{2}  - 7x  - 7

g(x) = x + 1

_________________________________

f(g(x)) = 2 ({x + 1})^{2} - 7(x + 1) - 7 \\

f(g(x)) = 2( {x}^{2}  + 2x + 1) - 7x - 7 - 7 \\

f(g(x)) = 2 {x}^{2} + 4x + 2 - 7x - 7 - 7 \\

Collect like terms

f(g(x)) = 2 {x}^{2} + (4 - 7)x - 14 + 2  \\

f(g(x)) = 2 {x}^{2} - 3x - 12
