Answer:
Proportionality equation: 
Linear equation: 
Step-by-step explanation:
So the amount that Cameron earns = 7/hr
Hours = x
And total earned amount = y
So we can form an equation from this for the total amount:

But the question asks us for a proportionality equation so:
Proportionality constant = k
So we get the equation:

All angles=40
therefore, internal angle= 140 degree
therefore, it has 5 sides
Answer: -20v^3 - 30x^2 +20
Step-by-step explanation:
simply multiply each term inside of the parentheses by -5.
65,000=6.5*10^4
In scientific notation
