Rewrite the equation y - 4= 2(x + 4) in slope-intercept form.
Karo-lina-s [1.5K]

First distribute the 2 through the parenthses on the right side.

So we have y - 4 = 2x + 8.

In slope-intercept form, the y is by itself on the left side.

So we add 4 to isolate the y on the left to get y = 2x + 12.

So in slope-intercept form, our equation is y = 2x + 12.

What is 62% of 25 ?<br> im horrible at this plz help
hodyreva [135]
62% of 25

'of' means multiplication.

\sf 62\%\times 25

Convert 62% to a decimal, divide it by 100(since percentages are parts of 100):

62/100 = 0.62

\sf 0.62\times 25

Multiply:

\sf\boxed{\sf 15.5}
