20x3 = 60 (total amount of hours he worked)
900/60 = $15 per hour
Answer:
y = 10
x = 64
Step-by-step explanation:
the equations containing y are adjacent angles in a parallelogram, meaning that they are supplementary, so we can create an equation:
5y + 2 + 12y + 8 = 180
solve this to get y = 10
the equation for x would be 2x + 5y + 8 = 180 because these angles are also supplementary
solve this to get x = 64
Answer:
y=7/2x−10
Step-by-step explanation:
Let's solve for y.
7x−2y=20
Step 1: Add -7x to both sides.
7x−2y+−7x=20+−7x
−2y=−7x+20
Step 2: Divide both sides by -2.
−2y/2=−7x+20/2
y=7/2x−10
Step-by-step explanation:
x³ - 4x = 0
x (x² - 4) = 0
x (x + 2) (x - 2) = 0
Thus the answer is (b) (-2 , 0) , (0 , 0) , (2 , 0)
