patriot [66]
The answer is a. <span>It represents a linear function because there is a constant rate of change. This can be done the opposite way, but lets use minutes as x and hours as y. Every time y increases by 1, x increases by 60. This means there is a constant rate of change of 1 (rise) over 60 (run). A linear equation must have a constant rate of change.</span>

Which equation shows y=−12x+4 is in standard form? 2x + y = 8 2x−y=8 x + 2y = 8 x+2y=−8
drek231 [11]

Answer:

<h2>x + 2y = 8</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

We have:

y=-\dfrac{1}{2}x+4

Convert:

y=-\dfrac{1}{2}x+4            <em>multiply both sides by 2</em>

2y=-x+8               <em>add x to both sides</em>

x+2y=8

AS a salesperson at trading cards unlimited Justin receives a monthly base pay plus commission on all that he sales. If he sales
Lelechka [254]
In this item, we will be able to form a system of linear equation which are shown below,
                                  292 = 400x + y
                                  407 = 900x + y
where x is the percent of the commission that he gets and y is the wage. The values of x and y from the equations are 0.23 and 200. This means that Justin earns a fixed wage of 200 per day and a commission which is equal to 23%. 

Substituting the known values to the equation,
                                   S = (0.23)(3200) + 200 = 936.

Therefore, Justin could have earned $936 had he sold $3,200 worth of merchandise.
