Answer:
(-2,3)
Step-by-step explanation:
Doing it the way you did and working out the problem you substituted 3 into, x+3(3)=7, 3(3) is 9 and then you subtract 9 from both sides.
7-9=-2
x=-2
Then all you have to do is put it into ordered pairs.
(x,y)
(-2,3)
Angle a,b,c equals 222; because angle a and b already is 180; so there is a right angle in the top with a 48 degree next to it so add then up and its 138; now subtract 180 which is the total of the total angels with 138 and you get 42; now add that to 180 and you get your answer which is 222.
X + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12
3x+6=-5-2x+6
3x=-5-2x
3x+2x=-5
5x=-5
x=-1
-4y = 8x
y = 8x/-4
y = -2x
The constant of variation is -2
