Question

Can some one help me with one of these 5 problems plzz

Answer 1

I can help with CL 2-107. All you have to do is simplify the equation on both sides, and then isolate w  to find its value.

6w - 5 + 8w - 2w - 3 = 9w - 24

(-5) + 12w - 3 = 9w - 24

-8 + 12w = 9w - 24

-8 + 3w = -24

3w = -16

w = $\frac{-16}{3}$

w = -5.33

Hope that helps! Sorry I couldn't help with the other ones!

Answer 2

Look at the pictures.

CL 2-109

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have

$(-5,\ 7)\to x_1=-5,\ y_1=7\\(10,\ 1)\to x_2=10,\ y_2=1$

Substitute:

$m=\dfrac{1-7}{10-(-5)}=\dfrac{-6}{10+5}=\dfrac{-6}{15}=-\dfrac{2}{5}$
