Mathematics

stepan [7]3 years ago

Answer:

C

Step-by-step explanation:

Given

\frac{x^2-16}{(x-16)(x+4)}

The numerator is a difference of squares

x² - 16 = (x - 4)(x + 4)

= \frac{(x-4)(x+4)}{(x-16)(x+4) } ← cancel the common factor (x + 4) on numerator/ denominator

= \frac{x-4}{x-16} → C

attashe74 [19]
Steps:
1. Substitute the y in y=4x + 4 and put
X-6=-4x+4
2. Add 4x to both sides
3. 5x-6=4
4. Add 6 to both sides
5. 5x=10
6. Divide by 5 on both sides
7. X=2
8. Now to find the y, you substitute 2 for x in the problem y=x-6
9. Y=2-6
10. Y=-4
11. Your answer is
(2, -4)
