Answer: x = 2

Step-by-step explanation:

<u>Given</u>

(1/4) (8x + 12) - 4x = -1

<u>Expand parentheses</u>

(1/4) (8x) + (1/4) (12) - 4x = -1

2x + 3 - 4x = -1

<u>Combine like terms</u>

-2x + 3 = -1

<u>Subtract 3 on both sides</u>

-2x + 3 - 3 = -1 - 3

-2x = -4

<u>Divide -2 on both sides</u>

-2x / -2 = -4 / -2

x = 2

Hope this helps!! :)

5. Two-thirds a number plus 4 i 7.​
eimsori [14]

Answer:

x = 9/2.

Step-by-step explanation:

2/3 x + 4 = 7

2/3 x = 3

Multiply both sides by 3/2:

2/3 * 3/2 x = 3 * 3/2

x = 9/2.

Help again lol

For the number before x you would look for the rise over the run. in this case you can see that there is an intersection at (-2,0) and (0,1) you find the difference ox each so you have 2/1 or just 2 you can tell that the line is going up so it is positive. for the addition part look at where the y intercept is in this case it is at positive one. this makes your equation y=2x+1

How do you solve it?
MatroZZZ [7]

Answer:

<em>i: </em>x=-2, x=1

<em>ii: </em>x=-1/2

Step-by-step explanation:

Quadratic form:

You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

(x+2)(x-1)=0

<em>"first"</em> would be x*x, which would equal x^{2}

<em>"outside"</em> would be x*-1, which would equal -1x, or -x

<em>"inside"</em> would be 2*x, which would equal 2x

<em>"last" </em>would be 2*-1, which would equal -2

Now you need to combine the terms so that they are one after the other

x^{2}-x +2x-2

Combine like terms, and you should get:

x^{2} +x-2

i Solution

<em>You need to get the variable by itself.</em>

<em>Subtract two from both sides</em>

x+2=0\\x=-2

<em>Add one to both sides.</em>

x-1=0\\x=1

ii Solution

<em>Add all the terms.</em>

x+2+x-1=0\\2x+1=0\\2x=-1\\x=-\frac{1}{2}
