The answer should be 7 mm :)
Answer:
no
Step-by-step explanation:
it's CASSANDRA business so she solve it herself
First distribute the 2 through the parenthses on the right side.
So we have y - 4 = 2x + 8.
In slope-intercept form, the y is by itself on the left side.
So we add 4 to isolate the y on the left to get y = 2x + 12.
So in slope-intercept form, our equation is y = 2x + 12.
Answer:
Step-by-step explanation:
Given
Let x represent the number of tickets, and p the charges
A reduction of 50c gives an increment of 50 tickets.
This gives:
----
Required
Determine the demand function
First, calculate the slope:
So, the equation is:
Hence, the function is:
You can solve this using an easy mathematical proportion:
you know that the car uses 20 gallons of fuel to travel 440 miles, so:
20 gallons : 440 miles = x : 1054 miles
The x is our unknown and stands for the fuel used to travel 1054 miles.
To solve it you should multiply the extreme knowns and then divide the result by the central known.
(20 gallons · 1054 miles) ÷ 440 miles
The unit miles cancel out so you're left with:
(21,080 gallons) ÷ 440 = 47.9 gallons ≈ 48 gallons
