Answer:
16
x=16
Step-by-step explanation:
divide both sides of the equation by 5
on the left side of the equation, any expression divided by itself equals one and on the right side of the equation 80÷5=16 so x=16
Answer:
∅
Step-by-step explanation:
The solution to the system of equations is the points of intersection of the 2 graphs.
Since the 2 graphs have no points of intersection there is no solution.
This is represented by the empty set ∅
The answer is choice D) Perpendicular from a point not on the line.
Answer:
{0}
Step-by-step explanation:
{0} is not because 0 is not an element of set {1, 2, 3}
The null set is a subset of every set, so Ø is.
A set is a subset of itself.
Answer:
Divide by 80 on both sides
