Manuela solved the equation below. what is the solution to manuela’s equation?

For this case we have the following equation:

Applying distributive property to the terms within the parentheses on the left side of the equation we have:

Subtracting "x" on both sides of the equation we have:

Subtracting 4 on both sides of the equation we have:

x = -8

Step-by-step explanation:

We are given that Manuela solved following equation and we are to find its solution:

Expanding the left side of the equation by multiplying the terms inside the bracket by 2:

Arranging the equation in a way such that like terms are on each side (variables on the left and constants on the right):

x = -8

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

answer

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
