He chose the right type of equation equation, but the equation should be y=15/x
Answer:
x=3
Step-by-step explanation:
When you substitute x = 3 to both equations, you get y = -4 for both so that is a solution
(1,2)
The solution is where the lines intersect so you can see they intersect at (1,2)
Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27
