Find the slope between the following points, show all work.<br> (-1, -8) and (-3, -2)
Hatshy [7]
How you get this answer is do delta y over delta x so that means take your y values (-8 and -2) and subtract and do the same thing with your x values so subtract (-1 and -3) so then youll end up with: -6 over 2, next steo is to see if you can simplify, and in this case you can so divide 2 and 6 so youll end up with -3 as your final answer. (this should be written in fraction form)

Factor 8x+16y+44 i offered up 15 points
belka [17]

Find the Greatest Common Factor (GCF)

GCF = 4

Factor out the GCF. (Write the GCF first, then in parenthesis, divide each term by the GCF.)

4(8x/4 + 16y/4 + 44/4)

Simplify each term in parenthesis

<u>= 4(2x + 4y + 11) </u>

Solve the systems of equations 6x+3y=9 2x+3y=1
patriot [66]
Solve by elimination.
The goal is to cancel out one of the variables in order to easily solve for the other variable.

Do this by changing the equations so that the coefficients of either x or y add up to 0.

Notice the coefficients of y are 3 and 3, if we make one of them negative then they add up to 0. 3+ (-3) = 0

Multiply 2nd equation by -1.

6x +3y = 9
-2x -3y = -1
__________
4x +0y = 8

Solve for x
4x = 8
x = 8/4 = 2

Plug x=2 back into one of original equations to find y.
---> 2(2) + 3y = 1
---> 4 + 3y = 1
---> 3y = -3
---> y = -1

Therefore solution is (2,-1)

Answer:

Step-by-step explanation:

both angles must add up to 180 so

6x+12+3x+63 must =180

= 9x+75

9x+75=180

     -75  -75

9x=105

x=11.66

meaning A is approximately 81.96
