Answer:
Number of jobs is 30
<em></em>
Step-by-step explanation:
<u>Variable representation</u>
Let Mark's total earnings for moving be m
Let Ryan's total earnings for moving be r
Represent the number of jobs with j
<u>Setup equation</u>
Mark:
So, the total savings is:
Ryan
So, the total savings is:
<u>To get the number of jobs they save the same amount.</u>
We have:
Substitute values for m and r
Collect Like Terms
Divide both sides by 5
<em>Hence, the number of jobs is 30</em>
The function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.
let the base of the triangle be x
Height of the triangle = x - 4
Area of triangle = 1/2 × base × height
Area = 1/2 × x × (x-4)
Area = 1/2 (x² - 4x)
Area = 1/2 x² - 2 x
We can also write it as a function:
y = 1/2 x² - 2 x
Domain = (3 , ∞)
Range = [0, ∞)
Since 3 is not included in the domain, base of the triangle cannot be 3 cm.
Therefore, the function is y = 1/2 x² - 2 x and the base of the triangle cannot be 3 cm.

Answer:
6y + 5x = -54
Step-by-step explanation:
y = m x + b -> slope-intercept form
ax + by = c -> standard form
6y = -5x - 54
6y + 5x = -54
