Given: X = r + 2, Y = 2r - 9, and Z = r 2 + 17r + 30. Simplify [X · Y - Z] ÷ X.
musickatia [10]

Answer: r - 24

Step-by-step explanation:

X=r+2;Y=2r-9;Z=r^2+17x+30

\frac{x*y-z}{x}

\frac{[(r+2)(2r-9)]-(r^2+17r+30)}{r+2}

\frac{(2r^2-9r+4r-18)-(r^2+17r+30)}{r+2}

\frac{(2r^2-5r-18)-(r^2+17r+30)}{r+2}

\frac{2r^2-5r-18-r^2-17r-30)}{r+2}

Combine like terms;

\frac{r^2-22r-48}{r+2}

Solve the quadratic equation;

\frac{(r-24)(r+2)}{r+2}

Simplify;

r-24

Point S is located on RT so that RS/ST = 1/4. What are the coordinates of Point S? (4 , 4 ) (2.4, 2.4) (8 , 8 ) (4.4, 4.4)
valina [46]

Answer:

  (4.4, 4.4)

Step-by-step explanation:

The point S can be found as the weighted average of the end points. The relative weights are the reverse of the distances to the end points:

  RS : ST = 1 : 4

  S = (4R +1T)/5

  S = (4(2, 2) +(14, 14))/5 = (22, 22)/5

  S = (4.4, 4.4)

Suppose the linear regression line y = 2.009x - 37.131 predicts a pizza
VARVARA [1.3K]

Answer:

Pizza parlor's profit = $515.344

Step-by-step explanation:

Given that:

Linear regression line for pizza parlor's profit

y = 2.009x - 37.131

x represents the number of pizzas sold

y represent the profit in dollars

Profit for 275 pizzas

Putting x = 275 in given equation

y = 2.009(275) - 37.131

y = 552.475 - 37.131

y = 515.344

Hence,

Pizza parlor's profit = $515.344
