Answer:
A. Yes. Each x value has only one y value. No x value has 2 different y values.
B. For the table, y is 8 when x is 11.
Plug in the value to determine the y value for the equation.
f(x)= 5(11)-21
f(x)= 55-21
f(x)= 34
Since 34>8, the value of the equation f(x) is greater when x=11.
C. 99=5x-21
120=5x
x=24
Final answer: 24

Answer:
5²x²- 49
Factoring: 25x2-49
A difference of two perfect squares, A²- B²can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A²- AB + BA - B²=
A² - AB + AB - B² =
A²- B²
25 is the square of 5
49 is the square of 7
x²is the square of x¹
(5x + 7) • (5x - 7)
