You need to find the slope first. (-9,-4). (3,4)

-4-4= -8
-9-3 =-12. Slope is -8/-12 or 8/12 or 2/3

Perpendicular is the negative reciprocal. Or flip over the 2/3 and make it negative.

The answer is - 3/2

The change in y as we move from the first point to the second is 8, and the corresponding change in x is 12. Thus, the slope of the line thru these two points is 8/12, or 2/3 (answer C).

The measure of angle GHI is 120. Angle GHI is in half with ray HK , if angle GHK is 3x+24 , What is the value of x?

denpristay [2]

Answer:

x = 12

Step-by-step explanation:

Angle GHK is half of 120, so is 60. Then ...

3x +24 = 60

3x = 36 . . . . . subtract 24

x = 12 . . . . . . . divide by 3

Find the slope of the line that passes through the points (-19, -4) and (13, -17).

Tasya [4]

Answer:

m = $\frac{-13}{32}$

Step-by-step explanation:

Two point slope formula = $\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

$\frac{-17 + 4}{13 + 19} = \frac{-13}{32}$

Answer:

A) A = 1; B = 0; C = 20

Step-by-step explanation:

The standard form for a quadratic is

Ax^2 +Bx +C=0

We are given

1/4x^2 + 5 = 0

Rewriting

1/4x^2 +0x+ 5 = 0

A = 1/4 B=0 C=5

We can multiply each side by 4

4(1/4x^2 +0x+ 5) = 0*4

x^2 +0x+ 20 = 0

A = 1 B=0 C=20
