Answer: 60 4 X 5= 20 x 3 = 60
Step-by-step explanation:
x+13⁰+10x+13⁰+2x-2⁰= 180⁰
13x= 180-24
13x=156
x = 12⁰
now angle Q = 10x+13⁰
= 10(12)+13= 120+13
= 133⁰
You have to distribute the minus sign to the second parenthesis, changing the sign of every term:
(-17,8)
(3,-2)
y-y1=m(x-x1)
where a point is (x1,y1)
and slope=m
slope of 2 points
(x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
(-17,8) and (3,-2)
(x,y)
slope=(-2-8)/(3-(-17))=-10/(3+17)=-10/20=-1/2
y-y1=-1/2(x-y2)
can be
y-8=-1/2(x+17) or
y+2=-1/2(x-3)
2nd option is the answer
(4,10).
1. There are three ways to solve this: elimination, substitution, graphing.
2. I chose elimination, so I had to get one negative variable and one positive variable of the same value (for example, 18 and -18)
-7x+2y=-8
-16x+9y=26
I chose to get 2y and 9y to equal -18y and 18y.
So, multiply the first equation by -9. Multiply the second by 2.
63x-18y=72
-32x+18y=52
the 18s cross each other out. So you're left with
63x=72
-32x=52. Add them.
31x=124, divide both sides by 31, and you'll get 4.
x=4
Plug your answer for x into one of the equations. Let's use the first one.
-7(4)+2y=-8
-28+2y=-8. add 28 to both sides.
2y=20, divide both sides by 2.
y=10.
This makes your answer (4,10)
