Answer:

D. -8

Step-by-step explanation:

An x intercept is where the y value is zero.

We set the expression equal to zero and solve for x.

x^2 - 64 = 0

(x + 8)(x - 8) = 0

x + 8 = 0 or x - 8 = 0

x = 8 or x = 8

Answer: D. -8

Answer:

$\frac{12}{19} \times \underline{\bold{-1}} = -\frac{12}{19}$

Step-by-step explanation:

$\frac{12}{19} \times ..... = -\frac{12}{19}$

= $\frac{\frac{12}{19}}{-\frac{12}{19}}$

= $\frac{12}{19} \times -\frac{19}{12}$

= $-\frac{228}{228}$

= $\bold{-1}$

So, the appropriate value to complete it is -1
