Answer:

B) x < 22.5; Sam has fewer than 22.5 minutes left to finish running.

Step-by-step explanation:

For this case we have the following inequality:

From here, we define the variable x.

x: number of minutes remaining to finish the race.

From here, we clear the value of x.

We have then:

Therefore, Samuel has less than 22.5 minutes to finish the race in the estimated time.

Answer:

x < 22.5; Sam has fewer than 22.5 minutes left to finish running.

Does the point (-4, 3) fall on the graph of this line? How do you know? Show your work. ( 2 points) PLEASE HELP ILL MARK BRAINLI

Elanso [62]

Answer:

Step-by-step explanation:

Since we know the line goes through points $(8,9)$ and $(2,4)$ , we can construct a line in slope-intercept form

$y = mx + b$

where $m$ is the slope and $b$ is the Y-intercept.

The slope can be found using the two points provided:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

$\frac{9 - 4}{8 - 2}$

$\frac{5}{6}$

The line is now represented as

$y = \frac{5}{6}x + b$

To solve for $b$ , we can plug in one of the two points:

$y = \frac{5}{6}x + b$

$(9) = \frac{5}{6}(8) + b$

$4 = \frac{20}{3} + b$

$b = \frac{-8}{3}$

We know have our line:

$y = \frac{5}{6}x - \frac{8}{3}$

To determine if the point $(-4, 3)$ falls on this line, we just plug the numbers into the equation and see if it holds true:

$y = \frac{5}{6}x - \frac{8}{3}$

$(3) = \frac{5}{6}(-4) - \frac{8}{3}$

$3 = \frac{-10}{3} - \frac{8}{3}$

$3 = \frac{-18}{3}$

$3 = -6$

This does not hold true, so the point is not on the line.

Can someone explain it to me. I don’t really understand.

Gala2k [10]

whichever number you pick (5-50) is represented by 'X'

'X' will be the amount of money you saved a week

The weeks are going to be represented by 'Y'

so the formula would be-

'X' x 'Y'= The amount of money saved over 4 years of high school

So you have to get the number of weeks in four years and multiply it by the number that you selected and that should give you the answer.

Hope this Helps :)
