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)

Evaluate the following expression:
Maurinko [17]

Answer:

1

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<br> 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 <em>y = mx + b</em> (linear function equation) and we need to find <em>m</em>.

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

Our final equation is:

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