Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2

1

slope intercept form that represents the new line.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

y=x-2

We know that Reflecting over the x-axis inverts the sign of the y-coordinate.

Thus, after reflecting over the x-axis, the equation would be:

-y = x - 2

Now, writing the equation in the slope-intercept form

y=mx+b

where

m is the slope and b is the y-intercept

so the equation in the slope-intercept form

-y = x - 2

y = -x + 2

Here,

The slope = m = -1The y-intercept = b = 2

Ezra has two weeks to sell popcorn to earn money for camp. For each unit of popcorn that he sells, Ezra will earn $5. He wants to earn at least $250
. During the first week he earned $105.
How many units of popcorn must Ezra sell in the second week to earn at least $250 in the two weeks combined?

Answers

okay so-
in the first week he sold 21 units of popcorn
he needs to sell 50 units in all
so 50-21= 29
he needs to sell 29 more units of popcorn

The number of units that needs to be sold to earn at least $250 is 20.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The minimum amount that needs to be earned = $250

One unit cost = $5

The amount earned in the first week = $105

Number of units = x

The number of units to sell in the second week.

150 + 5x ≥ 250

5x ≥ 250 -150

5x ≥ 100

x ≥ 20

Thus,

20 units need to be sold to earn at least $250.

the length of one side of a rectangle is p cm and width is 3(p-2) cm the perimeter is 44 cm find the length and width of rectangle​

Answers

Answer:

Length = 7cm, Width = 15cm

Step-by-step explanation:

Length = p

Width = 3(p-2)

          = 3p-6

Perimeter = length + width + length + width

                = p + 3p-6 + p + 3p-6

                = 8p-12

8p - 12 = 44

Isolate 8p.

8p = 44+12

    = 56

Find p.

p = 56 ÷ 8

p = 7

Length = 7cm

Width = 3(7)-6

          = 21-6

          = 15cm

there are 20% more goblins than wizards in magic club there are 120 goblins in magic club

Answers

Answer:

Final Answer: There are 100 wizards in the magic club

Step-by-step explanation:

Since this question is asking for how many wizards are in magic club, we can represent wizards with the variable "w"

w = wizards

Next, we know that there are 120 goblins and that there are 20% more goblins than wizards in magic club.

120 = w + 20%w

120 = w + 0.2w

(percentages are just the percent/100)

120 = 1.2w

1200 = 12w

100 = w

Cheryl paid $37.20 for 12 gallons of ice cream for a school picnic. how much would 1 quart of ice cream cost? group of answer choices $4.10 $0.68 $0.78 $3.10

Answers

Cheryl, that paid $37.20 for 12 gallons of ice cream for a school picnic would pay $0.78 for 1 quart of ice cream

To solve this problem, we have to state the equation using the information of the problem

Information about the problem:

Payment= $37.20Amount= 12 gallons1 quart cost=?

Converting the amount unit from gallon to quart, we get:

12 gallons * (4 quart / 1 gallon) = 48 quarts

12 gallons are equivalent to 48 quarts

Calculating how much would cost 1 quart of ice cream:

1 quart cost = payment / amount(quart)

1 quart cost = $37.20 / 48 quarts

1 quart cost = $0.78
