The local bakery sells cookies for $7.99 per dozen. which equation represents y, the total cost of x dozen of cookies?

Mathematics
1 answer:
Elenna [48]3 years ago
8 0

Answer:

y = 7.99x

Step-by-step explanation:

If y = total cost and x = dozen of cookies

Then y = 7.99x

This is because the price of the number of dozens of the cookies, multiply by the price of i dozen will be equal to the total cost price

A line is represented by the equation y/x-2=3/11. What are the coordinates of some points that line on the line?
Galina-37 [17]

y/x-2=3/11 would be easier to work with if we were to put it into a more standard form, e. g., y = mx + b.

First, add 2 to both sides, to isolate y/x:

y/x = 3/11 + 22/11 = 25/11.

Next, mult. both sides by x, to get y by itself:  y = (25/11)x.  

This is your function.

Now make a table.  You can choose any x values you want, and then calculate y for each one.

x   y

0  0

1   25/11

3  (25/11)*3 = 75/11

Then we have three points on this line: (0,0), (1, 25/11), 3, 75/11).  You could obtain more by choosing additional x values.

Luke and Joshua work at a dry cleaners ironing shirts. Luke can iron 35 shirts per
aniked [119]

Answer:

Step-by-step explanation:

Let x be the number of hours worked by Joshua.

Shirts ironed by Joshua in an hour = 25

Number of shirts ironed by Joshua in x hours = 25x

The number of hours worked by Luke = (x + 3)hours

Shirts ironed by Luke in an hour = 35

No. of shirts ironed by Luke in x hours = 35*(x + 3) = 35x+35*3 = 35x + 105

No. of shirts ironed by Luke and Joshua = 345

25x + 35x +105 = 345

60x = 345 - 105

60x = 240

x = 240/60

x = 4 hours

The number of hours worked by Joshua = 4 hours

The number of hours worked by Luke = 4 +3 = 7 hours

Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solu
Dmitry [639]
The place where two equations intersect, has a certain value of y. This means that in the intersection point, the y-values of both expressions are the same, so y = y. Since y is also represented by the following equations, y = 4x and y = 2x - 2, the x-value of the intersection point is 4x = 2x - 2.
