Answer: 36h, 60+16.2h, and $92.40.

Step-by-step explanation:

n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.

Answer:

f(x) = (-3/4)x^2 + 3

Step-by-step explanation:

First, look at the vertex to see if it intersects the y-axis. It does, which is good, because it makes your job a lot easier by making your equation to fill out y = ax + b. Your b is the y value of your vertex, which in this case is 3. Then, your a is the amount you're multiplying plain old x^2 by to get your values (before adding 3). Because the graph is pointing down, you know right away that it's going to be negative. Also, going to the left or right by 2 (the points you are given) from the vertex gives you a result of going down 3. Normally this would mean you move up by 4 (again, from the vertex), so what do you need to multiply 4 by to get -3? -3/4, so that's your a. This makes your equation (y OR) f(x) = (-3/4)x^2 + 3

I hope I didn't make any mistakes reading your graph! I had a bit of difficulty with it unfortunately.

Answer:

3n + 11 ≥ 50

Step-by-step explanation:

The word "sum" refers to addition as it is the term for the answer to an addition problem, so you know that there should be an addition sign in this inequality.

The word "times" means to multiply!

So you are multiplying 3 by some number which we will call it n. Now it says the SUM of 3n and eleven...meaning you are adding 3n and 11.

Greater than or equal to is a way of saying this symbol "≥" And "fifty" in numbers is 50

Your answer should be 3n + 11 ≥ 50

Hope this helps :)

Answer:

63 cents

Step-by-step explanation:

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?​

0.39/13 = 0.03in

o.03 X 21 = 0.63

so 63 cents  check

63/21 should equal 39/13

63/21 = 39/13

63 X 13  = 39 X21

21 X 3 X 13 = 3 X 13 X 21

yes

21 X 3 X 13 = 21 X 3 X 13

Answer:

-251x + 75

Step-by-step explanation:

-150x + 15 - 31x + 60 - 50x - 20x

-251x + 75

(I simplified it by combining all the like terms such as -150x, -31x, -50x, and -20x. Adding all of the negative numbers together gets you negative 251x. Then there are positive 60 and positive 15. Adding both positive numbers together gets you a positive 75. When I put both of the solutions together, I got -251x + 75)

Answer:

2y=x

Step-by-step explanation:

Normally, if there were the same amount of cats and dogs, the cats' feet would be quadruple the dogs' noses. But, the question states that it is double the dogs' noses. 2 x 2=4, so there are twice as many dogs as cats.

The equation of the line is y = -2

Answer:

Destroy the end crystals (using a bow for far range). If it spreads a poisonous gas, dig a hole and retreat there for a few seconds. Once you destroy all the crystals (since it’s it healing source), start attacking it with your sword once the dragon swoops down on the portal (it depends on the enchantments & the sword itself). Keep repeating that until the dragon is killed.

Answer:

kill it

Step-by-step explanation:

6x - 10 = 7x - 30

6x - 7x = -30 + 10

-x = -20

x = 20°

Value of x is 20°

Answer:

x = 20

Step-by-step explanation:

Given m||n meaning the lines are parallel: Two angles are alternate exterior angles and so their measure is same

7x - 30 = 6x - 10 export like terms to the same side of equation

7x - 6x = 30 - 10

x = 20

Answer:

140° and 50°

Step-by-step explanation:

The supplement of the angle (180 - x)

The complement of the angle = (90 - x)

(180 -x) = 4(90-x) - 60

180 - x = 360 -4x - 60

180 -x  = 300 - 4x

180 - x + 4x = 300

 180 + 3x = 300

     3x = 120

      x = 40

The supplement (180 - x) =  180 - 40 = 140°

The complement (90 - x) =  90 - 40 = 50°

Answer:  X=-4   Hope you get it right! :)

Answer:

<1 = 12.71 degrees

<2 = 77.29 degrees

Step-by-step explanation:

<1 = x

<2 = 6x - 1

x + 6x - 1 = 90 degrees

7x = 90 - 1

x = 89/7

x = 12.71

Answer:

A

Step-by-step explanation:

Using the sine ratio in the right triangle

sin ? = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{26}{29}[/tex] , then

? = [tex]sin^{-1}[/tex] ([tex]\frac{26}{29}[/tex] ) ≈ 64° ( to the nearest degree ) → A

Answer:

A

Step-by-step explanation:

[tex]Sin X = \dfrac{Opposite}{hypotenuse}\\\\Sin \ X =\dfrac{26}{29}\\\\X = Sin^{-1} \ (0.8965)\\\\x = 63.7[/tex]

x = 64

Yes, 13x and 7x+6x are equivalent. When you simplify 7x+6x you get 13x.

Answer:

Step-by-step explanation:

Answer:

y = 5(x² - 2) - 3

Step-by-step explanation:

    In y = a(x² - b) + c, a is the stretch factor, -b is the horizontal, and c is the vertical

    You did not give us the parent function, so I am going to assume it is y = x²

         y = x²

    3 units down means the function will be moved 3 units down, so it will look like:

         y = (x²) - 3

    Shifted 2 units to the right will result in a -2, so we add that in:

         y = (x² - 2) - 3

    The stretch factor is 5, which goes in front of everything else, multiplying the quadratic,

         y = 5(x² - 2) - 3

Have a nice day!
