Answer <u>(assuming the question allows it to be written in slope-intercept form)</u>:

y = -\frac{3}{5} x-\frac{9}{5}

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula m = \frac{y_2-y_1}{x_2-x_1}, substitute the given points' x and y values, and simplify:

m = \frac{(-3)-(0)}{(2)-(-3)} \\m  =\frac{-3-0}{2+3}\\m = -\frac{3}{5}

Thus, the slope is -\frac{3}{5}.

2) Now, use the point-slope formula y-y_1 = m (x-x_1) and substitute real values for m, x_1, and y_1.

Since m represents the slope, substitute -\frac{3}{5} in its place. Since x_1 and y_1 represent the x and y values of a point the line crosses, use the x and y values of any one of the given points to substitute into the formula. (Either one is fine. I chose (2,-3).) Then, isolate y to put it into slope-intercept form and find the answer:

y-(-3) = -\frac{3}{5} (x-(2))\\y + 3 = -\frac{3}{5} x + \frac{6}{5} \\y = -\frac{3}{5} x - \frac{9}{5}

Find the area of the shaded region.
sveticcg [70]

Answer:

12.86 sq ft

Step-by-step explanation:

Find area of square and subtract out area of semi-circle; the diameter of the semi-circle equals the side of the square, which is 4 so radius is 2

A(square) = 4 x 4 = 16

A(semi-circle) = πr²/2

= 4π/2 or 2π

Area of Shaded Region = 16-3.14 which is 12.86

Answer:

600 Cheese and 900 Pepperoni

Step-by-step explanation:

Setup the equation with 2c(Cheese) + 2.5p(Pepperoni) = $3450(Total Made).

In addition to the equation c + p = 1500(Number of pizzas sold)

Using the second equation (c + p = 1500) solve for one of the variables.

Lets use :

  1. p = 1500 - c
  2. Plus this equation into the original equation, 2c + 2.5(1500 - c) = 3450
  3. Distribute 2.5, 2c + 3750 - 2.5c = 3450
  4. Combine like terms -0.5c + 3750 = 3450
  5. Solve for c: c = 600
  6. Plus 600 in for c into any equation ( lets use c + p = 1500)
  7. 600 + p = 1500
  8. P = 900

What is the change in y- values for every two units of x-values?
schepotkina [342]

Answer:

The graph of y\:=\:\frac{1}{2}x  is also attached below, which indicates that there is a change of only one unit on the y-axis for every two units of x-values.

Step-by-step explanation:

When there is a change in x values, it is basically a horizontal change. horizontal change between two values is also called the run.

And the vertically change between two values is also called the rise.

The slope is basically the ratio of the vertical (rise) and horizontal (run) changes between two points on a line.

For example, consider the equation

y\:=\:\frac{1}{2}x

\mathrm{Slope\:of\:}\frac{1}{2}x:\quad m=\frac{1}{2}

Here fore every two units of x-values, one units are moved on the y-axis.

In other words, there is a change of only one unit on the y-axis for every two units of x-values.

The graph of y\:=\:\frac{1}{2}x  is also attached below which is showing this.
