X is -8

To solve the problem you have to get X by itself. So you would multiply every number in the equation by 4. Which will give you -X + 12 = 20

Now you have to subtract 12 on both sides of the equal side giving you -X = 8 since the positive twelve cancels out.

Finally you divide by negative 1 since X can NOT be a negative!

Your final answer should be X = -8

I hope that helped and you know what to do now...

QUESTION: 1 1/5 = -2 2/3 x +6 solve for x will give brainliest answer quickly or no brainliest.

Answer: $x=1\frac{4}{5}$

Simplify both sides of the equation

$\frac{6}{5} =\frac{-8}{3} x+6$

Flip the equation

$\frac{-8}{3} x+6=\frac{6}{5}$

Subtract 6 from both sides

$\frac{-8}{3} x+6-6=\frac{6}{5} -6$

$\frac{-8}{3} x=\frac{-24}{5}$

Multiply both sides by 3/(-8)

$(\frac{3}{-8} )*\frac{-8}{3} x)=(\frac{3}{-8} )*(\frac{-24}{5} )$

$x=\frac{9}{5}$

Turn 9/5 into a Mixed Number

$x=\frac{9}{5} =1\frac{4}{5} \\x=1\frac{4}{5}$

Does it open up or down and is it shifted to the left 2 units or to the right 2 units of function g(x)

mixas84 [53]

It opens down if the lead coefficient is negative

And it shifts to the left by two. Always use the opposite of what is in parenthesis, which in this case is 2.
