To find the price per shirt, simply divide the total (combined) cost of the shirts by the amount of shirts

A.) $26.96 (cost of 6 shirts) ÷ 6 (shirts) = $4.49 per shirt

B.) $21.00 (cost of 5 shirts) ÷ (5 shirts) = $4.20 per shirt

C.) $28.50 (cost of 7 shirts) ÷ (7 shirts) = $4.07 per shirt

Comparing A, B, and C, the best buy would be C ($28.50 for 7 shirts)

I need help solving this problem.
Galina-37 [17]

Answer:

y = \frac{1}{4} x - \frac{9}{2}

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 38 is in this form with slope m = - 4

The line ST is perpendicular to line RS ( angles in a square are 90° )

Given a line with slope m then the slope of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{-4} = \frac{1}{4}

y = \frac{1}{4} x + c ← is the partial equation

To find c substitute (2, - 4) into the partial equation

- 4 = \frac{1}{2} + c ⇒ c = - 4 - \frac{1}{2} = - \frac{9}{2}

y = \frac{1}{4} x - \frac{9}{2} ← equation of ST

Solve the differential equation: dy/dx = 4y2x1/3
labwork [276]
The first thing you should do is use the method of variable separation. Then, integrate both sides to find the solution.
 In this case the answer is
  <span>D. - 1/y = 3x4/3 + C</span> 
 I attach the solution
