Answer:
x=-2, y=1
Step-by-step explanation:
y=3x+7
y=-2x+3
Set the two equations equal to each other:
3x+7=-2x-3
Add 2x to both sides:
5x+7=-3
Subtract 7 from both sides:
5x=-10
Divide both sides by 5:
x=-2
Plug back into one of the original equations to find y:
y=3(-2)+7=-15+7=1
Hope this helps!
C. 75. The answer is C because both sides are congruent, showing each angles would equal the same amount

Answer:
I would try saying that it is a real number
Step-by-step explanation:
This is the concept of algebra, given that the room is 150 sq. feet, the dimensions of the room can be found as follows;
Suppose the room is a perfect square, the length=width= x ft
therefore the are will be:
area=length*width
=x*x=x^2 sq. ft
hence;
x^2=150
getting the square root of both sides we get:
sqrt x^2=sqrt150
x=sqrt150
x=12.248 ft
x=12 ft (to the nearest feet)
