Step-by-step explanation:

Simplify the following expression then state the property used:

9^-2

Property:

Given,

9^-2

For any real numbers a and b a, b ≠ 0, and for any two positive integers, n and n

a^-m

=> 1/a^m [By doing reciprocal]

So,

9^-2

=> 1/9^2

=> 1/(3^2)^2

=> 1/(3^4)

=> 1/(3*3*3*3)

=> 1/81. Ans.

Hope this helps.

Serggg [28]

y = (x - 2)(x + 5)    First I would multiply (x - 2) and (x + 5) together

y = x² + 5x - 2x - 10

y = x² + 3x - 10


Next I would plug in a number for x to find its y value. I will plug in 0

y = 0² + 3(0) - 10

y = -10

(0, -10)   [this is the y-intercept (the y value when x = 0)]


Your answer is Graph A because the y-intercept is (0,-10)
