A. Graph D
B. Graph B
O C. Graph A
D. Graph C
Answer:B
Step-by-step explanation:
Option B is correct, the inequality y≥-2x-2 is represented in the second graph or graph B.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given inequality is y≥-2x-2
y greater than or equal to minus two times of x minus two.
y≥-2x-2
The line passes through the points (-2, 2) and (0, -2).
As there is given greater than or equal to the line should be solid not dotted.
Greater than or equal to means we have to shade away from the origin.
The second graph satisfy all these properties.
y≥-2x-2 is represented in the second graph.
Hence, the inequality y≥-2x-2 is represented in the second graph.

Find the product (у- 2)(5у2 + 3y - 1)
Answer:
5y^3 - 7y^2 - 97y + 2 <<<< Answer
Step-by-step explanation:
(у- 2)(5у2 + 3y - 1)
Multiply the three terms by y
5y^2 * y + 3y * y - 1*y = 5y^3 + 3y^2 - y
Multiply the three terms by - 2
-2*5y^2 -2*3y - 2*-1
-10y^2 - 6y + 2
Now combine the like terms

Shayla is going to paint a wall. The wall is 23 feet long by 8 feet high. A gallon of paint costs $11 and covers 320 square feet of area.
If the wall requires two coats of paint, what is the minimum cost of painting Shayla's wall?
Answer:
$12.65
Step-by-step explanation:
Given that the wall is 23 feet long and 8 feet high.
As the wall is rectangular, so the area of the wall,
A=23x8=184 square feet.
As a gallon of paint costs $11 and covers 320 square feet of area, so
Cost of paint for 1 square foot area = $ 11/320 per square foot.
Cost for 1 coat of paint = $ (11/320)x184
Cost for 2 coat of paint = $ (11/320)x184x2= $ 12.65
Hence, cost requires for 2 coats of paint is $ 12.65.

Answer:
listen to the other guy
or girl
Step-by-step explanation:
It will take at least 14 weeks to have at least $500.
What is inequality?The relation between two unequal expressions is defined as inequality.
Given that, the person has $150 in his account and he deposits $25 each week into this account.
The amount in the account after w weeks is:
150 + 25w
Let the amount in the account after w weeks is at least $500, then it follows:
150 + 25w ≥ 500
25w ≥ 500 - 150
25w ≥ 350
w ≥ 14
Hence, it will take at least 14 weeks to have at least $500.

Diana is going camping with her family. Their campsite is 7/8 miles away. They walk at a steady speed of 2 1/2 mi/h. How many minutes will it take them to get to the campsite
Answer:
21 minutes
Step-by-step explanation:
Using the formula to calculate the time expressed as;
Speed = Distance/Time
Given:
Distance = 7/8 miles
Speed = 2 1/2 mi/hr
Required
Time in minutes
Substitute the given values into the formula;
Recall that:
S = D/T
T = D/S
Time = 7/8 ÷ 2 1/2
Time = 7/8 ÷ 5/2
Time = 7/8 * 2/5
Time = 7/4 * 1/5
Time = 7/20 hour
Since 1 hour = 60 minutes
7/20 hour = (7/20 * 60)minutes
7/20 hour = 7 * 3
7/20 hour = 21 minutes
Therefore it will take them 21 minutes to get to the campsite

Sara says, "If you subtract 14 from my number and multiply the difference by - 3, the result is – 42."
What is Sara's number?
Sara's number is |
Answer:
Sara's number is 28
Step-by-step explanation:
Let's assign Sara's number the variable x and solve this equation using the information provided.
"If you subtract 14 from my number"
x - 14
"and multiply the difference by - 3"
-3(x - 14)
"the result is – 42."
-3(x - 14) = -42
Now we can solve from here for x.
-3(x - 14) = -42
x - 14 = 14
x = 28

Put the following numbers in order from least to greatest.
0.52
0.6
14/25
57%
Answer:
57% 0.52 14/25 0.6
Step-by-step explanation:
all you have to do is change all of the numbers into decimals
hope this helps :)
First, convert each to the same (#/#, 0.#, or #%). I'll use decimals (usually the easiest). 0.52 and 0.6 remain the same. 14/25 may seem hard at first, but you can change it to 56/100 (14*4/25*4=56/100), then you can use that to convert to 56%. Multiply by 0.01, or divide by 100, remove the %, and you will get 0.56. For 57%, you just need to do repeat the last step again, which will give you 0.57. From least to greatest, the list would be 0.52, 0.56, 0.57, and 0.6, or 0.52, 14/25, 57%, and 0.6.
