Which point is a solution to the system of linear equations?

y = −x + 3
2x − y = 6

A: (3, 0)
B: (3, −1)
C: (0, 3)
D: (−1, 3)

Answers

Using y=-x+3 and 2x-y=6 your solution would be (3,0)

Which ordered pair is the reflection of (3, 10) across the x-axis?
Responses

A. (3, −10)

B. (−3, −10)

C. (−3, 10)

D. (10, 3)

Answers

Answer:

C. (-3,10)

Step-by-step explanation:

When reflecting across the x-axis you will always be entering into a negative x quadrant if you are reflecting from the positive quadrants. Reflecting over the x-axis makes no change to the y values, only the x. So you answer would be (-3,10) because you are making the x value 3, negative by reflecting over the x-axis.

-Hope this Helped

CORRECT ANSWER: A

ITS JUST REFLECTION meaning it’s direct opposite of 3,10 so it’s 3,-10

Al has a cylindrical storage container 30 cm tall with a diameter of 22 centimeters. how much bird food in cubic centimeters will fit in the container? use the formula V=BH and approximate pi using 3.14\

ROUND UR ANSWER OT THE NEAREST TENTH

Answers

Answer:

11398.2 cm²

Step-by-step explanation:

So the formula of the volume of cylinder is already given. We need to put numbers in side of the formula V = Bh to find the volume(V)

so the base(B) can be find by πr² which is π × radius × radius

We know that radius is equal to half of diameter, so the base area is equal to:

22 ÷ 2 = 11 cm

3.14 × 11 × 11 =  379.94 cm

And then we calculate for the volume, the volume formula is above, it is base × height, which is:

379.94 × 30 = 11398.2 cm²

Answers

I did that last year, basically both sides of the hangar have to be equal.
And the number at the top is what all the shapes on the hanger equal, so each side of the hangar equals 18 because it is half of 36.
You are trying to figure out what each shape equals.

Explanation of Answer:
There is only one shape on the left so since the left side has to equal 18 the yellow triangle equals 18.
And the right side equals 18 as well so you know how much the green one is worth so subtract 3 ( the green one) from 18 which is 15. Then to find out how much ONE blue moon is worth you divide 15 by how many moons there are which would be three so 15 divided by 3 is 5 making the moons worth 5.

Answer:
Yellow triangle: 18
Green: 3
Blue moon: 5

Hope this helped sorry if it was messy!
Both sides will have the same equal number.
So, basically have to half the main number, which is 36. So, it'll be both sides will have to equal to 18.

So, yellow is 18.

It is given that the green is worth 3. 18 - 3 = 15. 15 divided by 3 is 5. Therefore, blue is 5.

•
Yellow = 18
Blue = 5
Green = 3

Suppose that the volume of a right circular cylinder is 288 cubic meters and the area of its base is 16 square meters. What is the height of the cylinder?


A. 12 m
B. 16 m
C. 18 m
D. 14 m

Answers

Hello:

--> find the height of the cylinder

Let's find the equation for finding the volume of the cylinder:

 [tex]\text{Volume}=\pi r^2*h[/tex]

    - -> now [tex]\pi r^2[/tex] is the area of the base, which is a circle that is 16

      - -> the volume is 288

        - -> let's plug in all the known values

               [tex]288=16*h\\\\h=\dfrac{288}{16} \\\\h=18[/tex]

Thus the height is 18 meters

Answer: 18 m

The answer is 18 I don’t have a fancy explanation but I wrote everything out on paper and I got 18 I hope this helped! (I’m sorry if this is the wrong answer)

Soda: A cup of soda costs a restaurant an average of $0.12 per cup (This includes the price of the cup, lid, straw and soda). However, they charge an average of $3.00 at the restaurant. Calculate the percent of this markup.

Answers

Answer:

2400%

Step-by-step explanation:

To calculate the percent markup, we need to first find the difference between the cost and the selling price: $3.00 - $0.12 = $2.88

Then, we can divide that difference by the cost and multiply by 100% to express the result as a percentage:

($2.88 / $0.12) * 100% = 2400%

So the percent markup on the cup of soda is 2400%.

2400% if I'm not mistaken

A linear relationship is given in the table.


x y
6 −2
2 2
0 4
−2 6


What is the slope of the relationship?
−2
−1
1
2

Answers

Answer:

-1

Step-by-step explanation:

Pick any two points such as (0, 4) and (2, 2).

slope = (difference in y)/(difference in x)

slope = (4 - 2)/(0 - 2)

slope = 2/(-2)

slope = -1

If you take two points (0,4) & (2,2) and subtract the change in y over the change in x, and then simplify, you will get (4 - 2)/(0-2), which is equivalent to (2)/(-2). 2 divided by -2 is -1, and that’s how you get your slope. :)
