4x+8=2x+7+2x-20

Combine like terms: 4x+8=4x-13
Subtract 8 from each side: 4x=4x-21
Subtract 4x from each side: 0= -21
There are no solutions to this equation.

<span>We simplify the equation to the form, which is simple to understand
<span>4x+8-2x=20

We move all terms containing x to the left and all other terms to the right.
<span>+4x-2x=+20-8

We simplify left and right side of the equation.
<span>+2x=+12

We divide both sides of the equation by 2 to get x.
<span>x=6</span></span></span></span></span>

dalvyx [7]

Answer:

2/4, 3/6, and 4/8

Step-by-step explanation:

Equivalent fractions are made by multiplying the numerator and denominator by the same factor.

For 1/2, you can multiply the top and bottom by 2, 3, or 4 to get 2/4, 3/6, and 4/8 respectively.

F(x)=x2 what is g(x)?
Oksi-84 [34.3K]

g(x) = (1/4)x^2 . correct option C) .

<u>Step-by-step explanation:</u>

Here we have , f(x)=x^2  and we need to find g(x) from the graph . Let's find out:

We have ,  f(x)=x^2   . From the graph we can see that g(x) is passing through point (2,1 ) . Let's substitute this point in all of the four options !

A . g(x) = (1/4x)^2

Putting (2,1) in equation g(x) = (x/4)^2 , we get :

⇒ g(2)= (\frac{2}{4} )^2

⇒ 1\neq \frac{1}{4}

Hence , wrong equation !

B . g(x) = 4x^2

Putting (2,1) in equation g(x) = 4x^2 , we get :

⇒ g(2)=4(2)^2

⇒ 1\neq 64

Hence , wrong equation !

C . g(x) = (1/4)x^2

Putting (2,1) in equation g(x) = (1/4)x^2 , we get :

⇒ g(2)= (\frac{1}{4} )2^2

⇒ 1= 1

Hence , right equation !

D . g(x) = (1/2)x^2

Putting (2,1) in equation g(x) = (1/2)x^2 , we get :

⇒ g(2)= (\frac{1}{2} )2^2

⇒ 1\neq 2

Hence , wrong equation !

Therefore , g(x) = (1/4)x^2 . correct option C) .

Complete the point-slope equation of the line through (-1,6)(−1,6)left parenthesis, minus, 1, comma, 6, right parenthesis and (1
velikii [3]

Answer:

y-6 = -\frac{1}{2} (x+1)

Step-by-step explanation:

For this case we have two points given (-1,6) and (1,5)

And we want to complete the point slope equation of the line:

y-6 = m(x-x_o)

We need to find the slope and we can use the following formula:

m = \frac{y_2 -y_1}{x_2 -x_1}

And replacing the info we got:

m= \frac{5-6}{1-(-1)}=-\frac{1}{2}

And then the equation would be given by:

y-6 = -\frac{1}{2} (x- (-1))

And our final answer would be:

y-6 = -\frac{1}{2} (x+1)
