Vitek1552 [10]

Answer: 205

Step-by-step explanation:

Initially, Jill received ballots from the student council election = 45

After, dropping ballot by Mr. Alvarez, new ballots he has = 250

Hence, The Ballots drooping by Mr. Alvarez = new ballots Jill has - Initial ballots Jill has

= 250 - 45

= 205

Therefore, Mr. Alvarez drop off 205 ballots.

Mila [183]

C-53.62 times however many she bought.

so c-(53.62x)

because you are taking how much money she spent and subracting it from how much she had

What is the slope?<br>if possible can you explain?

Mandarinka [93]

Answer:

$m = \frac{4}{5}$

Step-by-step explanation:

The slope of a graph is also known as its gradient, which is the steepness of the graph.

If we are given two points on the line, we can find the slope by taking rise/ run, which is the ratio of the change in y-coordinate against the change in the x-coordinate. This can also be written as a formula:

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate

In this question, we are given the equation of the line. This equation is already in the slope-intercept form (y= mx +c) since the coefficient of y is 1 and all the other terms are on the other side of the equal sign. In the slope-intercept form, m is the slope while c is the y-intercept.

m= ⅘ since the coefficient of x is ⅘ in the given equation (when the equation is in the slope-intercept form).
