So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
Answer:
see below
Step-by-step explanation:
For simplifying expressions of this sort, there are four rules of exponents that come into play;

__
I find it convenient to eliminate the fractions by adding the exponents, then rewrite any negative exponents as denominator factors.

Answer:
y = 14x
Step-by-step explanation:
Use the direct variation equation, y = kx
Plug in 7 as y and 0.5 as x, and solve for k:
y = kx
7 = k(0.5)
14 = k
Plug this into the equation:
y = kx
y = 14x
So, the equation of variation is y = 14x
The point (250,0) of the graph represents that the average price per ticket is $250.
Given to us
x is the price the passenger paid
f(x) is the positive percent difference
<h3>What is the correct interpretation of the point (250, 0)?</h3>
We know that a coordinate is written in the form of (x, y), therefore, the point (250, 0) represents that the price of the ticket is 250, while the 0 in the coordinate represents that there is no percentage difference. Since the point (250,0) is the mid-value of the x-axis on the graph, we can say that $250 is the average price of the ticket.
Hence, the point (250,0) of the graph represents that the average price per ticket is $250.

450/500 how much you have to how much it costs
this equals to 90 % of the complete cost
100%-90%=10%
you need a 10 % discount
hope this helps
