−2x+15y=−24
2x+9y=24
−2x+15y=−24
2x+9y=24
Add the two equations together.
-2x +2x = 0
15y + 9y = 24y
-24+24 = 0
The two equations when added become:
24y = 0
Solve for y:
divide both sides by 24:
y = 0/24 = 0
The value of Y is 0
Now replace Y in one of the equations and solve for x:
2x+9(0) = 24
2x + 0 = 24
2x = 24
Divide both sides by 2:
x = 24/2
x = 12.
The value of x is 12
The solution is (12,0)
Answer:
The solution is ( x , y ) = ( 12 , 0 )

Answer:
Step-by-step explanation:
in total there is 6x
180/6=30
x=30
2x=60
3x=90
Answer:30°
Step-by-step explanation:
Thera are 3 angles in a triangel. The sum of all angles is 180°
x+2x+3x=180
6x=180
x=180/6=30
1) 2(1.5n + 4) -6n= -7
2) 5s - 2 + 3 (s - 11) = 5
Answer:
OM = 411.56 ft
Step-by-step explanation:
tan 11 = 80/x
0.1944 = 80/x
x = 411.56 ft
Answer:
There is not a way that I can show you how to graph it, so I will try and explain it.
Step-by-step explanation:
(1,1)
^ ^ y-axis
x-axis
You are just going right however many, and then up however many it says.
So if it's (1,1) you will go right one space, and then up one space.
Once you have all of your points on the graph, you put a line through them.
Hope this helps! :)
