Answer:

<GHI = 135 degrees

Step-by-step explanation:

(3x + 12) + (x + 4) = 180

4x + 16 = 180

4x + 16 - 16 = 4x

180 - 16 = 164

4x = 164

4x / 4 = x

164 / 4 = 41

x = 41

3 * 41 + 12

3 * 41 = 123

123 + 12 = 135

What is an equation of the line that passes through the point (8,-8)(8,−8) and is perpendicular to the line 4x-3y=184x−3y=18?

Kitty [74]

Answer:

The equation of the line is $y = -\frac{3x}{4} - 2$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Perpendicular lines:

When two lines are perpendicular, the multiplication of their slopes is -1.

Perpendicular to the line 4x-3y=18

First, we place this line into the format, to find the slope:

$4x - 3y = 18$

$3y = 4x - 18$

$y = \frac{4x}{3} - 6$

This line has slope 4/3. So, for the perpendicular line, the slope will be of m as such:

$\frac{4m}{3} = -1$

$4m = -3$

$m = -\frac{3}{4}$

So the desired line will have an equation in the following format:

$y = -\frac{3x}{4} + b$

Passes through the point (8,-8)

We use this to find b. This point means that when $x = 8, y = -8$ . So

$y = -\frac{3x}{4} + b$

$-8 = -\frac{3*8}{4} + b$

$-8 = -6 + b$

$b = -2$

$y = -\frac{3x}{4} - 2$

What is -8(2-3w)-5<br><br> Please explain!

MArishka [77]

Answer:

24w - 21

Step-by-step explanation:

-8(2 - 3w) - 5

We first expand the -8

-16 + 24w - 5

We then add -16 to -5

-16 + -5

= -21

We get the 24w, put in in the equation and get 24w - 21
