On a piece of paper, graph y> -2x -2 . Then determine which answer choice matches the graph you drew.
Answer:
C) Graph B
Step-by-step explanation:
All of these equations have the line y = -2x - 2 graphed.
In the inequality, we have the symbol greater than or equal to. This tells us the line drawn must be solid, not dashed. This means the correct graph is either B or D.
Since it is greater than or equal to, the shaded area must be above the line. This is graph B.
We need to therefore plot the graph passing through the coordinate point (0, -2) and (-1, 0). Option B is correct
Graph of inequality functionsInequality are expression not separated y an equal sign. For an inequality, the upper graph is shaded for greater than and the lower part shaded for less than sign.
Since the sign is greater than and equal to, hence the line will be a solid line as shown in the graph.
Given the inequality y≥ -2x -2. Find the intercepts
If x = 0
y = -2(0) - 2
y = -2
The y-intercept is at (0,-2
If y = 0
0 = -2x - 2
2x = -2
x = -1
The x-intercept is at (-1,0)
We need to therefore plot the graph passing through the coordinate point (0, -2) and (-1, 0) as shown

Step-by-step explanation:
jeffrey purchased a card for $180 that gives him 20 visits to a new gym and includes a one-time fee for unlimited use of the sauna. After 5 visits, Jeff has $123.75 left on the card, and after 11 visits, he has $74.25 left on the card. Write an equation that Jeffrey can use to determine the cost of each visit and the fee for the sauna use.
There is many ways to do this but i did it this way.
180-123.75= 56.25
56.25/5=11.25
=11.25
The value of the sauna fee is $ 15, while each visit to the gym is worth $ 8.25.
Since Jeffrey purchased a card for $ 180 that gives him 20 visits to a new gym and includes a one-time fee for unlimited use of the sauna, and after 5 visits, Jeff has $ 123.75 left on the card, and after 11 visits, he has $ 74.25 left on the card, to determine an equation that Jeffrey can use to determine the cost of each visit and the fee for the sauna use the following calculation must be performed:
The difference between the remaining sum after 5 visits and 11 visits should be obtained, and then divided by 6 to obtain the value of a visit to the gym. Then, you must multiply this result by 20, and subtract the result from the initial value of 180 to know the value of the sauna fee.
(123.75 - 74.25) / 6 = X 49.5 / 6 = X 8.25 = X 180 - (8.25 x 20) = X 180 - 165 = X 15 = X
Therefore, the value of the sauna fee is $ 15, while each visit to the gym is worth $ 8.25.

The length of a rectanglewith area 54 square centimeters is 9 centimeters. What is the perimeter of the rectangle, in centimeters?
So, first we have to find the width.
Area of a rectangle = length * width
54 = 9 * width
width = 6cm
Now we can plug this into the perimeter formula.
2w + 2l = P
P = 2(6) + 2(9)
P = 12 + 18
P = 40

How do I factor trig functions?
I am stuck on how to factor out equations like 1+sinX-cos2x=0
I am confused on where to go from here to solve the equation. Pls help.
Use cos2x =1-2sin^2x
1+sinx- (1-2sin^2x) = 1+ sinx -1+2sin^2x
=sinx+2sin^2x=sinx(1+2sinx)
Therefore
Either sinx=0 or 1+ sin2x =0

Lucy has 4 inches of ribbon that she wants to cut into 6 equal sized pieces. What is true about the length of each piece of ribbon. A) each piece has 6/4 inches of ribbon B) each piece has 1/4 of 6 inches of ribbon C) each piece has 1/6 of 4 inches of ribbon
Answer:
Option C
Step-by-step explanation:
Given
Total length of ribbon lucy has=4 inches
She wants to divide it into 6 equal sized pieces so
Length of each piece=4/6
This can also be written as:
Length of each piece=4*(1/6 )
Now we will look at the options one by one:
For A, Each piece has 6/4 inches of ribbon.. This statement is not true as we have to divide 4 inches into 6 pieces so 4 is supposed to be in the numerator.
For B, breaking down 4/6 gives us 4*(1/6), so the statement is not true.
For C , as we can see that the expression is 4*(1/6), each piece will have 1/6 of inches of ribbon.
So option C is the correct answer..

rosie is going on a 312-mile road trip. if she wants to make the drive in 6 hours, at what constant rate will she need to drive in terms of miles per hour?
312miles/6hours=52mph
52mph
To make the 312-mile road trip in 6 hours, Rosie would need to drive at a constant rate of 52 miles per hour.
Explanation:To find the constant rate at which Rosie needs to drive, we can divide the total distance by the total time. In this case, Rosie needs to drive 312 miles in 6 hours. So the rate would be 312 miles ÷ 6 hours = 52 miles per hour.

A wall is 26 inches wide. Twelve inches is concrete, 9 inches is brick, and 5 inches is limestone. What fraction of the wall is concrete?
The fraction of the wall that is concrete is obtained by dividing the width of concrete (12 inches) by the total wall width (26 inches). This gives a fraction of 12/26, which simplifies to 6/13. Therefore, 6/13 of the wall is made of concrete.
Explanation:To solve this problem, we can express the width of the concrete part of the wall as a fraction of the total wall width. First, we will identify the total width of the wall, which includes the different sections of concrete, brick, and limestone. In this case, that is 26 inches (12 inches of concrete + 9 inches of brick + 5 inches of limestone = 26 inches).
Next, we need to determine the width of the concrete section, which is 12 inches.
To express the width of the concrete wall as a fraction of the total wall width, we divide the width of the concrete part by the total wall width. So, we have: 12 inches / 26 inches. Therefore, the fraction of the wall that is concrete is 12/26, which simplifies to 6/13. Out of every 13 parts of the wall, 6 parts are made up of concrete.

the masses of four cars loaded on a car transporter are 2.1 tonnes 3.7 tonnes 2.8 tonnes and 1700kg what is the total mass in tonnes
To find the total mass of the four cars, first convert the mass given in kilograms to tonnes, and then sum all the masses. The total mass of the cars on the car transporter is 10.3 tonnes.
Explanation:The total mass of the four cars loaded on a car transporter can be calculated by first ensuring all the masses are in the same unit. The masses are given as 2.1 tonnes, 3.7 tonnes, 2.8 tonnes, and 1700 kg. We must convert the mass given in kilograms to tonnes before we add them together, as there are 1000 kg in a tonne.
To convert 1700 kg to tonnes:
1700 kg ÷ 1000 = 1.7 tonnesNow that all masses are in tonnes, we sum them up:
2.1 tonnes3.7 tonnes2.8 tonnes1.7 tonnesTotal mass in tonnes = 2.1 + 3.7 + 2.8 + 1.7 = 10.3 tonnes.
Therefore, the total mass of the four cars on the car transporter is 10.3 tonnes.

We have been given that Elyse needs 3 gallons of water to mix a fruit drink, but she has a 1-cup measuring cup. She knows that there are 4 cups in 1 quart, and 4 quarts in 1 gallon.
Elyse can use the unit rate. First she can multiply 4 cups in a quart by 4 quarts per gallon to find that there are 16 cups in 1 gallon. She can then multiply 3 gallons by 16 cups per gallon to determine that she will need 48 cups of water to mix the fruit drink.
