The dot starts at 7 with the arrow going towards the left.

Seeing how 15 on the right side (of all inquealities) is positive, that means if we subtract both sides from positive 8, we will get positive 7 on the right side.

So we want the variable x to be equal to 7 or less than 7.

ELIMINATE choice F.

ELIMINATE choice H & J.

<h3>ANSWER: choice G</h3>

Answer:

We have been given an equation x^2+9x+20=0

We will factorize it by  middle term splitting.

Step 1: x^2+5x+4x+20=0

Taking common factors out by clubing first two terms ad last two terms

Step 2: x(x+5)+4(x+5)=0

Step 3: (x+4)(x+5)=0

Equating both above factors to zero as:

Step 4: (x+4)=0\Rightarrow x=-4

   And (x+5)=0\Rightarrow x=-5.

Can someone help me with my algebra?
SIZIF [17.4K]

Answer:

The top graph

Solutions:

-2

0

Step-by-step explanation:

The given quadratic function in factored form is

f(x) =  - (x + 2)(x - 2)

This is a parabola that has x-intercepts at (-2,0) and (2,0)

This parabola opens downward because the leading coefficient is less than 1.

The second function is

g(x) = 2 |x  + 2|

This is an absolute value function with vertex at (-2,0).

Therefore the graph that shows the solution to f(x)=g(x) is the top graph.

Hence the solution is x=-2,x=0
