(4x-7y)(4x+7y)
4x times 4x= 16x^2
-7y times 7y= -49y^2
His hourly rate is $13.75.
Let x be the hourly rate. Since he works 20 hours that week, the hourly wages are given by 20x. We add to that his commission, which is 16% of the $1500 in sales, or 0.16(1500). This totals to 515:
20x + 0.16(1500) = 515
20x + 240 = 515
Subtract 240 from both sides:
20x + 240 - 240 = 515 - 240
20x = 275
Divide both sides by 20:
20x/20 = 275/20
x = 13.75.
Answer:
<h2>B. The slope is 5 and (2, 4) is on the line.</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point</em>
<em />
We have the equation:

Therefore
<em>m = 5</em>
<em>(x₁, y₁) = (2, 4)</em>
<em />
Answer:
