Lisa specializes in baking lemon cupcakes. She bakes 3 dozen cupcakes every hour. The cost (in dollars) of making n cupcakes is given by the function C(n) = 60 + 0.45n.
The function that models the number of cupcakes Lisa makes in h hours is n(h) =
. The cost function in terms of hours, h, is given by
. Lisa's cost for making cupcakes for 2 hours is
.
Answers
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.

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

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.

Write the equation of a quadratic function that has been shifted 3 units down, to the right 2 units, and
stretched vertically by a factor of 5.
Answers
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

-150x +15-31x +60-50x -20x
Answers
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)
In the park, there are some cats and dogs. The number of cats’ feet is double the number of the dogs’ noses. The number of cats is how many times the number of dogs? Let x be the number of cats, and y be the number of dogs. Write the expression that will help you to solve the problem (expression here). The number of cats is what times the number of dogs.
Answers
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 sum of three times a number and eleven is greater than or equal to fifty
Answers
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

What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box.
Answers
How:
- As you can see the line goes through the y axis at 2- so we can substitute the c in y=mx + c for 2
- To find the gradient use two points on the line and count across and up, I used (-4,-6) and (0,2) which was 2 across and 4 up: 4 divided by 2 is 2 giving us the gradient to substitute the 2 as m into y=mx+c
That gives us y=2x+ 2

The measure of the supplement of an angle is 60° less than four times the measure of the complement of the angle. Find the measure of the angle.
Answers
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°
Find the quadratic function represented by the following graph.
Answers
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.
