Answer:

When x is -6, y will be 18

When x is -5 y will be 15

Step-by-step explanation:

Create a proportion

y/x

-9/3 = x/-6  What do we need to multiply 3 by to get 6?  -2, so we will multiply -9 by -2 to get 18

Some people like to solve by cross multiplying.

That would give us

(-9)(-6) = 3x  

54 = 3x  divide both sides by 3

18 = x

Set up the second problem as a proportion

-9/3 = x/-5  This is a little trickier.  I am trying to think what I have to multiply 3 by to get -5.  3(-5/3)  will give me -5, so I will multiply the top number that I know (-9) by (-5/3) to find my x.

(-9)(-5/3) = 45/3  or 15

HELPP PLEASE ASAP Use the Pythagorean theorem to find the missing length in the right triangle

The pythagoras theorem :

a² + b² = c²

a = 6 and b = 8

6² + 8² = c²

36+64 = c²

100 = c²

c = √100

c= 10

Question 19 makes no sense
gavmur [86]
Think:  To write the equation of a line in slope-intercept form y=mx+b, you must have the slope (m) and the y-intercept (b). 

g(0)= -6 tells us that the y-intercept is (0, -6).  Thus, b= -6.

(0,-6) and (15,-9) are points on the line.  Find the slope of the line.  It is:
          -9-(-6)
m = ------------- = -3/15 = -1/5
          15-0

Thus, the equation of the line in question is y=(-1/5)x - 6.

Important that you understand that g(0)=-6 is also represented by (0,-6), and that -6 is the y-intercept.
