15 minutes per mile or 15x because of the unspecified amount of miles
7 minutes total so +7
and at least 52 minutes total so...
15x + 7 > 52

Question
A delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year. Which function best models the linear relationship? y = 22,000x − 40,000 y = –22,000x + 40,000 y = 22,000x + 40,000 y = 40,000x − 22,000
Solution 1

The function that best models the linear relationship will be y = 22,000x + 40,000.

Let the number of years be represented by x.

From the information given, the delivery truck has 40,000 miles on its odometer and travels an average of 22,000 miles per year, this will then be;

y = 40000 + (22000 × x)

y = 40000 + 22000x

Therefore, the function that best models the linear relationship will be y = 22,000x + 40,000.

Well, y-intercept is what we start with(40000) and the slope is the rate of increase/decrease(22000).
Question
Estimate the unit rate to the nearest hundredth. $1.19 per 12fl oz price of 1 fl oz Solution 1 Unit rate is used in mathematics to compare one quantity with another quantity. The unit rate to the nearest hundredth is$0.010

From the question, we know that 12 fl oz is $1.19. To find the unit rate, 12 fl oz =$1.19

1 fl oz = ?

Cross Multiply

1 fl oz x $1.19 / 12 fl oz =$0.099166

To the nearest hundredth, the unit rate is $0.010 Therefore, the unit rate to the nearest hundredth is$0.010

I believe the price of 1 fl oz. would be 0.09916667.

Question
In a box of pens, there are three times as many red pens as green pens and two times as many green pens as blue pens. For the pens in the box, write down the ratio of the number of red pens to the number of green pens to the number of blue pens.
Solution 1

The ratio of the numbers of red, green and blue pens is 3:1:2

### What is ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that, In a box of pens, there are three times as many red pens as green pens and two times as many green pens as blue pens.

Let the number of green pens be x,

Then the number of red pens = 3x

Number of blue pens = 2x

Ratio = 3x:x:2x

= 3:1:2

Hence, the ratio of the numbers of red, green and blue pens is 3:1:2

Question
Given the slope and y-intercept can you write an equation for the line?
Solution 1
Y=mx+b
m=slope
b=yintercept

example
if slope=3
yintercept is 2 then
y=3x+2
simple as that
Solution 2
Yes, because the equation to find the proportional relationship is y=kx. Y- origin
K- constant rate of proportionality
