7xy-8x because you distribute the x even if there is another variable inside the parentheses
Answer:
The amplitude is 4 and the period is 2
Step-by-step explanation:
In the equation y = A sin (B x)
- A is the amplitude, where the amplitude is the height from highest to lowest points and divide the answer by 2
- The period is
, where the period is the distance from one peak to the next peak
∵ The equation is y = 4 sin(πФ)
- Compare it with form above
∴ A = 4 and B = π
∵ A is the amplitude
∴ The amplitude is 4
∵ Period =
∴ Period = 
∴ Period = 2
∴ The period is 2

Hope that helps
Grosspay = 2,300 + .21 * gross pay
.79 * Gross Pay = 2,300
Gross Pay = 2,911.39
********************************************
Double-Check 2,911.39 * .21 = 611.39
2,911.39 - 611.39 = 2,300.00
Correct !!!
159
10 squared is 100
Do the 5+3 next to get 8 then square the 8 to get 64
That leaves you with 100+64-5=159
