Answer:

-14x + 5y - 3

Step-by-step explanation:

well -4x-5(2x-y)-3y (Distributed)

-4x -10 x + 5y - 3

Than you collect like terms, like subtract 4 and 10 (negative so basically addition)

than you get

-14x + 5y - 3

Evaluate the following expression:

Maurinko [17]

Answer:

Step-by-step explanation:

${6}^{2} - 7(8 + 6 - {3}^{2})$

Using BODMAS we'll have to solve what is in the bracket first

$= {6}^{2} - 7(14 - 9) \\ = {6}^{2} - 7(5) \\$

Multply -7 by 5 still using the rule of BODMAS

$= {6}^{2} - 35 \\ = 36 - 35 \\ = 1$

Write an equation that describes the line that passes through (2, 2) and (0, -3).

gtnhenbr [62]

Answer:

f(x) = $\frac{5}{2}$ x

Step-by-step explanation:

The first thing we need to find is the slope of the line able to pass through the given two points. Right now we have y = mx + b (linear function equation) and we need to find m.

Using the slope formula or $m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$ and plugging in the given points' x and y values:

$\frac{-3-2}{0-2}$ = $\frac{-5}{-2}$ = $\frac{5}{2}$

The slope of the line is that for every 5 units the line goes upwards, it goes 2 units to the right.

Our equation is now y = $\frac{5}{2}$ x + b. If you were in need of it, b gives the line's y-intercept, the place where it hits the y-axis. In this case you do not need b because the only specified conditions in the problem are the units the line hits.

Our final equation is:

f(x) = $\frac{5}{2}$ x
