Answer:
y=−4 and x=5
Step-by-step explanation:
y=−4;y=(
(−2)
5
)(x)−2
Step: Solvey=−4for y:
Step: Substitute−4foryiny=
−2
x−2:
y=
x−2
−4=
−4+
2
x=
x−2+
x(Add 2/5x to both sides)
x−4=−2
x−4+4=−2+4(Add 4 to both sides)
x=2
x
=
(Divide both sides by 2/5)
x=5
Answer:Exact Form: one over 9
1
9
Step-by-step explanation: ,..
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to
By geometric mean theorem:
