A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Anoth
sveticcg [70]

Answer:


Step-by-step explanation:

Let each turkey sandwich cost x, and the fixed delivery fee be y.

From the first situation, 4x + y = 33

From the second case with 8 sandwiches, 8x + y = 61

Subtracting the first equation from the second gives 4x = 28

x = 7

Substituting this back into the first equation gives y = 5.

Therefore, each turkey sandwich costs $7 and the delivery fee is $5.

If you were to have 12 turkey sandwiches delivered, the cost would be 12x + y = 12*7 + 5 = $89, so this would be more than $85.


If you want to do it graphically, convert both equations into slope-intercept form.

y = -4x + 33 and y = -8x + 61

For the first equation, the y-intercept is (0,33) and the x-intercept is (33/4, 0).

For the second equation, the y-intercept is (0,61) and the x-intercept is (61/8, 0).

Connect the intercepts for each equation, then find the point of intersection. The x- and y-coordinates of the point of intersection are x = 7 and y = 5, which are the values that will solve the equations.

Which shows the image of rectangle ABCD after the rotation () (W)?<br> 13<br> VA<br> 1<br> V
IgorLugansk [536]

Answer:

Graph (1)

Step-by-step explanation:

Given rule for the rotation of a figure is,

A(x, y) → A'(-y, x)

This rule defines the rotation of point A by 90° counterclockwise about the origin.

Coordinates of point A → (-2, 0)

Coordinates of point C → (-1, 0)

Following the rule of rotation,

A(x, y) → A'(-y, x)

A(-2, 0) → A'(0, -2)

C(-1, 4) → C'(-4, -1)

Now search the image points from the graphs attached,

Graph (1) will be the answer.

How would you find the missing x and y values if you don’t have a model or equation to go by?
mamaluj [8]
You can find the slope and y-intercept, and make an equation in slope- intercept form and them just plug in the other x values in the equation.
