Hello,

(x-4)(x+8)(x-2)(x-5i)(x+5i)
=(x^2+4x-32)(x-2)(x^2+25)
=(x^3+2x^2-40x+64)(x^2+25)
=x^5 +2x^4 -15x^3 +114 x^2-1000x+1600

$\displaystyle\sqrt[3]{4 - \frac{x^2}{3}} = -2 \\\\ 4-\dfrac{x^2}{3}=-8\\\\ 12-x^2=-24\\\\ x^2=36\\\\ x=6 \vee x=-6\\\\ 6-(-6)=6+6=12$

Which linear inequality is represented by the graph?

Serga [27]

Answer:

A. y ≤ 1/2x + 2

Step-by-step explanation:

Well look at the graph,

It is a solid line with it shaded down,

meaning it is y ≤,

So we can cross out B. and D.

So the y intercept is 2, we know this because the y intercept is the point on the line that touches the y axis.

now the slope can be found by seeing how far away each points are from each other,

Hence, the answer is A. y ≤ 1/2x + 2
