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>
Answer:
<h2>x + 2y = 8</h2>
Step-by-step explanation:
The standard form of an equation of a line:

We have:

Convert:
<em>multiply both sides by 2</em>
<em>add x to both sides</em>

Answer:
3x +45°=180° (due to straight angle)
or, 3x= 180°-45°
or,3x= 135°
or,X=135°/3
X =45°.ans
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.
To simplify by distribution we proceed as follows;
7a(3b-2c+4)
=7a*3b-2c*7a+4*7a
=21ab-14cb+28a
the answer is:
21ab-14cb+28a
