22x
It’s the same as 12 plus 10
214 divided by 9 is 23.7777 etc so add two more tickets 216 divided by 9 is 24 so they would need to buy two more tickets to equally divide the tickets
$2.10/6 oz= $0.35 per oz
$0.35 per oz* 20 oz= $7
Final answer: $7
Answer:
Part 1) Slope-intercept form
Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
Step-by-step explanation:
Part 1) we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have

This is a linear equation in slope intercept form
where


Part 2) we have that
x -----> represent the number of miles
y ----> represent the total charge in dollars
The slope is
---> unit rate
The y-intercept is
----> initial value or flat fee
therefore
The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee
F(x)=5-3x³
f'(x)=-9x²
f'(3)=-81
y+76= -81(x-3)
y+76=-81x+243
y=-81x+167
