Find the equation of the line passing through the points A (2,1) B (7,9)
Bezzdna [24]
m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{9 - 1}{7 - 2} = \frac{8}{5} = 1\frac{3}{5}
              y - y₁ = m(x - x₁)
               y - 1 = 1³/₅(x - 2) Point - Slope Form
               y - 1 = 1³/₅(x) - 1³/₅(2)
               y - 1 = 1³/₅x - 3¹/₅
                 + 1           + 1
                    y = 1³/₅x - 2¹/₅ Slope - Intercept Form
         -1³/₅x - y = 1³/₅x - 1³/₅x - 2¹/₅
          -1³/₅x - y = -2¹/₅
     -1(-1³/₅x - y) = -1(-2¹/₅)
-1(-1³/₅x) + 1(y) = 2¹/₅
           1³/₅x - y = 2¹/₅ Standard Form
         1³/₅(0) - y = 2¹/₅
                0 - y = 2¹/₅
                    -y = 2¹/₅
                    -1    -1
                     y = -2¹/₅ Y - Intercept
               (x, y) = (0, -2¹/₅)

pishuonlain [190]

Answer:

He sold 180 chicken sandwiches and 150 burguers.

Step-by-step explanation:

Since 330 items were sold, then the amount of burguers and chicken sandwiches sold must be equal to this value. From this information we have:

burguers + sandwiches = 330

We know that each burguer cost $9 and each chicken sandwich cost $11.25 and that we made a total of $3,375. So we have:

9*burguers + 11.25*sandwiches = 3,375

From the first equation we have:

burguers = 330 - sandwiches

Applying it on the second equation:

9*(330 - sandwiches) + 11.25*sandwiches = 3,375

2,970 - 9*sandwiches + 11.25*sandwiches = 3,375

2.25*sandwiches = 3,375 - 2,970

2.25*sandwiches = 405

sandwiches = 405/2.25 = 180

So,

burguers = 330 - 180  = 150

He sold 180 chicken sandwiches and 150 burguers.
