7 0

Answer:

\textbf{$a^2 + 4a + 16$}\\

Step-by-step explanation:

\textup{Given:}\\$$ \frac{a^3 - 64}{a - 4} $$\\\textup{This can be written as:}\\$ (a - 4)(a^2 + 4a + 16) $ \hspace{25mm} $[ (a^3 - b^3) = (a - b)(a^2 + ab + b^2)]$\\

\textup{Here $b = 4$}\\\textup{Now, it can be written as}\\$$ \frac{(a - 4)(a^2 + 4a + 16)}{a - 4} $$\\\textup{which renders us}\\

$$a^2 + 4a + 16$$

The graph of a line passes through the two points (-2,1) and (2,1)
Vinil7 [7]

Answer: if you graph these points, you'll see that the line is horizontal, so the slope is zero. It will cross the y axis (y intercept) at y=1.

Step-by-step explanation:

Slope = y2-y1/x2-x1, so in this example:

m = 1-1/it doesn't matter because the answer will be zero!!

Now for slope intercept form:

y = mx + b

y = 0x + b; take one of your points and plug it in:

1= 0(2)+ b

1=0 + b

1=b

So your equation is:

y= 0(x) + 1

y=1

Vinil7 [7]
Ax^2 + bx + c
a = 1
b = -4
c = -5
x^2 -4x-5

-5x1 = -5
-5+1 = -4
(factors of c that also add up to b)
