Rounded off to the nearest full number, it would be 3 rounds but that wouldn't make sense because 3 x 10 is 30 sooooo the answer would be 3.5 meaning you paid 1 fifth the price of 10 rounds.
Answer:
f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
= ( x + 9)(x +9)
= ( x + 9)²
= x² + 18x + 81
Hope this helps.
Answer:
y = -3
Step-by-step explanation:
The equation of the line is y = -x -2
We plug in the given x value into the equation to find y.
