There are fewer than 40 students enrolled in a certain class. If, at a certain time, 2/9 of the students are absent from school

sladkih [1.3K]

Well, we kinda hope that noone is splitting the students into parts;) so that means that the number of students must be divisible by 4 and 9, and since they don't have any divisors in common, it must be divisible by 4*9=36, and this is also the correct answer - 36.

-4(x-5 ) - 25 = -5 x =?*

patriot [66]

Answer:

x=0

Step-by-step explanation:

First distribute -4 to x and -5 and get -4x+20-25=-5

Then you combine like terms and get -4x-5=-5

Then add 5 to both sides and get -4x=0

Then divide both sides by -4 and get x=0

The graph of a linear function is shown on the grid.

Elza [17]

Answer:

Option (A)

Step-by-step explanation:

Let the equation of the line passing through a point (x', y') and slope 'm' is,

y - y' = m(x - x')

Slope of the line passing through two points (0, 5) and (4, -7),

m = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{5+7}{0-4}$

= -3

As slope of the line is negative, Options (A) and (B) will be the possible options.

Therefore, equation of the line passing through (4, -7) will be,

y - (-7) = -3(x - 4)

y + 7 = -3(x - 4)

Therefore, Option (A) will be the correct option.
