Answer:

29/4 or 7.25

Step-by-step explanation:

Complimentary angles are two angles that add up to 90

Supplementary angles are two angles that add up to 180

Angle ABC = x

Angle CBD = 7y + 4

Angle DBE = 8y + x

If we can find the measure of angle CBD, then we can find x.

We know that CBD + DBE = 180 because they are supplementary. Therefore...

(7y + 4) + (8y + x) = 180

AND

(7y + 4) + (x) = 90

Now we can use algebra to solve for x and y...

Blah blah blah...

x = 29/4

y = 45/4

Input m = -4 n = 2 and p = 1.5 into the expression above

7m + 2n - 8p/n
= 7(-4) + 2(2) - 8(1.5)/2
= -28 + 4 - 6
= -30

What is the slope of the line that passes through the points (2, 8) and (6, 12)?

zubka84 [21]

Yeah, where I live, to find the slope (or as we call it, the gradient), you just have to do the two y values subtracted from each other, over the two x values subtracted from each other. The important thing is to remember that if you subtract the first y value from the second (so, 12 - 8), you have to do the same thing for the x (6 - 2)

$\frac{12-8}{6-2}$ = $\frac{4}{4}$ = 1.

The slope is 1.
