Answer:

x = ± 2.45

Step-by-step explanation:

Given

8x² - 48 = 0 ( add 48 to both sides )

8x² = 48 ( divide both sides by 8 )

x² = 6 ( take the square root of both sides )

x = ± $√(6)$ = ± 2.45 ( nearest hundredth )

How do you find the slope of a line?

Answers

-- Pick any small piece of the line.

-- From the left end to the right end of that piece, measure
how much the line rises or drops.

-- Measure how much horizontal distance that piece covers.

-- Divide the amount of rise or drop by the horizontal distance.
That number is the slope of the line.

-- If the line drops as it goes from left to right, then the slope is negative.
