Trough: (2,2) parallel to y=x+4
Vlada [557]

Answer:

  y = x

Step-by-step explanation:

The slopes of parallel lines are the same, so we know the equation will be ...

  y = x + constant

We can find the constant by using the given point's values for x and y:

  2 = 2 + constant

Obviously, the constant is zero.

The equation of the parallel line through (2, 2) is y = x.

Ryleigh receives her pay monthly. Her deductions include $112 in Federal Income Tax, State Tax of 3.5% of gross, City Tax of 2.5
vodka [1.7K]

9514 1404 393

Answer:

  $6,106.87

Step-by-step explanation:

The total of percentage deductions is ...

  state tax + city tax + social security + medicare

  = 3.5% +2.5% +6.2% +1.45% = 13.65%

Then Ryleigh's take-home pay is ...

  gross(1 -13.65%) -112 = 5161.28

  gross = (5161.28 +112)/0.8635 = 6106.87

Ryleigh's monthly gross is $6,106.87.
