Inside the square root shouldn't be negative, so x must be negative in order to form positive number inside the root.

if x = 0, y = 0
if y = -1, y = -1
if y = -4, y = -2
if y = -9, y = -3

the points lie on the graph (0,0), (-1,-1), (-4,-2), (-9,-3)

What does m equal 2+2m=6

Lorico [155]

2 + 2m = 6 equals m = 2.

First, subtract 2 from both sides. Your problem should look like: 2m = 6 - 2.
Second, simplify 6 - 2 to get 4. Your problem should look like: 2m = 4.
Third, divide both sides by 2. Your problem should look like: m = $\frac{4}{2}$
Fourth, simplify $\frac{4}{2}$ to 2. Your problem should look like: m = 2, which is the answer.

Andy used a scale of Inch - 2 feet for a drawing of his house. On the drawing, a rectangular room measures 3 inches by 2 inches.

nexus9112 [7]

Answer:

$ 117.36

Step-by-step explanation:

On the drawing, the rectangular room measures 3 inches by 2 inches, we can convert to feet (using a scale of Inch - 2 feet )

(3 inches ×2) by (2 inches ×2)

= 6 feet by 4 feet

The Area of the room can now be calculated as

Area=( 6 feet × 4 feet)

= 24 ft^2

how much will the new carpet cost?

we know that the carpet costs $4.89 per square foot, then the cost by the area of the room= (Area× $4.89 per square foot)

=24 ft^2 x $4.89

=$ 117.36

Hence, the new carpet cost is $ 117.36

Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $8 per hour. Le

Contact [7]

Answer:

A C

Step-by-step explanation:

Answer:

Step-by-step explanation:

Leah wants to earn at least 120 dollars a month and she has two job options. This is written as

5x + 8y > 120

She also can't work more than 20 hours, leading us to the second equation

x + y = 20

First we solve for one variable

y = 20 - x

then substitute it into the first equation

5x + 8(20 - x) = 120

Solve for x

5x + 160 - 8x = 120

3x = 40

x = 40/3

Then we solve for y

y = 20 - x

y = 20/3

x < 40/3

y > 20/3

B and D will not work because their x+y is greater than 20.

E will also not work because the value is less than 120
