2y^2+ 2(9y^2 -8)
= 2y^2+ 18y^2 -16 (distributive property)
= 20y^2 -16

The final answer is 20y^2 -16~

You will need to multiply in the parentheses. so 2y2+2(9y2-8) you need to multiply 2(9y) and 2(2) and 2(-8).

Rewrite the equation in exponential form, and show how you got there:

Brut [27]

Answer: $13^0=1$

Step-by-step explanation:

Logarithms are in the format $log_{b} a=c$ while exponential form is in the format $b^c=a$

So we can transfer a,b, and c from the log form to the exponential form

$log_{13} 1=0\\\\13^0=1$

How to write -2x + y = -3 in slope intercept form? Preferably with steps.

Montano1993 [528]

Answer:

y = 2x - 3

Step-by-step explanation:

Start by writing out the given equation.

-2x + y = -3

The goal is to isolate the variable y.

For this equation, all you need to do is add 2x to each side.

-2x + y + 2x = -3 + 2x

Therefore, the answer is y = 2x -3.

I don't know if you are are familiar with the equation y = mx + b, but here's a little refresher. m is the slope, or in this case 2. b is the y-intercept, or in this case -3.

The equation y = mx + b is slope intercept form, so if you know this, you should be able to write any equation in slope intercept form.

Hope this helps!
