Answer: 18
Step-by-step explanation:
Answer:
x=1
x=-5
Step-by-step explanation:
we know that
The solution of the system of equations is the intersection point both graphs
In this problem there are two intersection points
so
The system has two solutions
we have
one solution is the point (-4.9, 5.4) and the other (0.92, -0.42)
see the attached figure
therefore
x=1
x=-5
Step-by-step explanation:
y=mx+b
3x+4y=8
move 3x to the other side
sign changes from +3x to -3x
3x-3x+4y=-3x+8
4y=-3x+8
divide both sides by 4 to get y by itself
4y/4=-3x/4+8/4
y=-3x/4+2
y=-3/4x+2
answer:
-3/4x+2
