Answer:
b=−ax+4a+3x
a= b−3x −x+4
Step-by-step explanation:
The values of a and b make the solution of the equation x = -5 are 1 and -6
How to determine the values of a and b?The equation is given as:
a(4-x) = -3x+b
When x = -5, we have:
a(4+5) = -3(-5)+b
Evaluate the products
9a = 15 + b
Set a = 1
9(1) = 15 + b
Make b the subject
b = 9 - 15
b = -6
Hence, the values of a and b make the solution of the equation x = -5 are 1 and -6

catrina earns $19.32 an hour. If she works a 40 hour each week consistently and takes only 2 weeks off for vacation in a year. How much will her annual earnings be?
Answer:
$38,640.00
Step-by-step explanation:
We know that Catrina earns $19.32 an hour. We also know she works 40 hours a week. So first, let's multiply 19.32 by 40 to see how much she makes a week.
19.32 × 40 = 772.80
Because of this, we now know that Catrina makes $772.80 a week. There are 52 weeks in a year. However, since she takes 2 weeks of vacation, we need to take off 2 weeks in the year. This leaves us with 50.
Finally, we multiply 772.80 and 50 to find her annual earnings:
772.80 × 50 = 38640
Therefore, her annual earnings will be $38,640.00.

Abbys mother is making treat bags for the 30 students in abbys class. She purchased bags at 5 for 1 candy bars at 10 for 0.50 and whistles at 3 for 0.75. If she puts 1 candy bar and 1 whistle I’m each bag how much will Abbys mother spend not including tax?
Answer:
Abby's mother spent $9.75 for the classroom not including tax.
Step-by-step explanation:
Know:
5 bags for 1 dollar
10 candy bars for 50 cents
3 whistles for 75 cents
5×6=30
10×3=30
3×10=30
5 times 6 is thirty. So find the product of 6 and 1 which is 6. 6 is the overall cost of bags.10 times 3 is 30. So find the product of 3 and .50 which is 1.50. 1.50 dollars is the overall cost of candy bars.3 times 10 is 30. You then find the product of 3 and .75. The product of this is 2.25 which is the total cost of whistles.Next you add all the values together which are 6.00 + 1.50 + 2.25 this equals $9.75You have space in your garden for 50 small flowering bulbs. Bulb A cost $0.45 each and
bulb B cost $0.65 each. Your budget allows you to spend $26.90 on bulbs. How many of bulb A and how many of bulb B can you buy?
_______number of bulb A
_______number of bulb B
Answer:
A = 28
B = 22
Step-by-step explanation:
All money will be recorded in pennies
Let A = the 45 Bulb
Let B = the 65 bulb
A + B = 50 (1)
45A + 65B = 2690 (2)
Multiply (1) by 45 and subtract that from (2)
45A + 65B = 2690
45A + 45B = 2250 Subtract
20B = 440
B = 22
A + B = 50
A + 22 = 50
A = 50 - 22
B = 28
Check
45*28 + 22* 65 =
1260 + 1430 = 2690

Find the midpoint of the segment with the following endpoints.
(8,9) and (4,3)
Answer:
The midpoint of the segment is (6,6).
Step-by-step explanation:
To solve this problem, we are going to use the midpoint formula, which is shown below:
( (x1+x2)/2, (y1+y2)/2 )
If we plug in the values that we are given in the question, we get:
( (8+4)/2, (9+3)/2)
We should add together the two numbers in the numerator of each fraction to begin the simplification process:
(12/2, 12/2)
Now, we can perform the division to find our final answer.
(6,6)
Therefore, the correct answer is (6,6).

3. In the same opera theater personal balcony sections with three rows of seating are being mapped as well. In
these sections there must be an odd number of seats in each row and each row must have two more seats
than the one before it. The last stipulation is that the front row must have one quarter the total seats in the
back 2 rows combined. How many seats will be in each row?
Answer:
Number of seats in first row = 2
Number of seats in 2nd row = 4
Number of seats in 3rd row = 6
Step-by-step explanation:
Let's say number of seats in first row is x.
Now we are told that each row must have two more seats
than the one before it.
Thus, the remaining 2 rows have;
(x + 2) and (x + 4) seats respectively.
We are told that that the front row must have one quarter the total seats in the
back 2 rows combined.
Thus;
x = ¼((x + 2) + (x + 4))
Multiply both sides by 4 to give;
4x = x + 2 + x + 4
4x = 2x + 4
4x - 2x = 4
2x = 4
x = 4/2
x = 2
Thus;
Number of seats in first row = x = 2
Number of seats in 2nd row = (x + 2) = 2 + 2 = 4
Number of seats in 3rd row = (x + 4) = 2 + 4 = 6

Yuppietown has two food stores, La Boulangerie, which sells bread, and La Fromagerie, which sells cheese. It costs $1 to make a loaf of bread and $2 to make a pound of cheese. If La Boulangerie’s price is P1 dollars per loaf of bread and La Fromagerie’s price is P2 dollars per pound of cheese, their respective weekly sales, Q1 thousand loaves of bread and Q2 thousand pounds of cheese, are given by the following equations: Q1 = 14 − P1 − 0.5P2 and Q2 = 19 − 0.5P1 − P2. (a) For each store, write its profit as a function of P1 and P2. Then find their best-response
Answer:
Step-by-step explanation:
Given that:
Q1 = 14 − P1 − 0.5P2
Q2 = 19 − 0.5P1 − P2
Recall that:
Profit = Total revenue - Total cost
π₁ = P₁Q₁ MCQ₁
π₁ = P₁(14 - P₁ - 0.5P₂) - Q₁
π₁ = 14P₁- P₁² - 0.5 P₁P₂ - 14 + P₁ + 0.5P₂
π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14
π₂ = P₂ (19 - 0.5P₁ - P₂) - 2(19 - 0.5P₁ - P₂)
π₂ = 19P₁ - 0.5P₁P₂ - P₂² - 38 + P₁ + 2P₂
π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38
The profit functions are π₁ & π₂
The best-response function from firm 1 is;
π₁ = 15P₁ - P₁² - 0.5P₁P₂ + 0.5P₂ - 14
[tex]\mathbf{\dfrac{\partial \pi_1}{\partial P_1}= 15 - 2P_1 -0.5P_2 =0}[/tex]
[tex]\mathbf{P_1= \dfrac{15-0.5P_2}{2}}[/tex]
The best-response function from firm 2 is;
π₂ = 21P₂ - P₂² - 0.5 P₁ P₂ + P₁ - 38
[tex]\mathbf{\dfrac{\partial \pi_2}{\partial P_2}= 21 - 2P_2 -0.5P_1 =0}[/tex]
[tex]\mathbf{P_2= \dfrac{21-0.5P_1}{2}}[/tex]
Here we must find the profit for each one of the two stores.
For La Boulangerie the profit is: (14 − P1 − 0.5*P2)*(P1 - $1)For La Fromagerie the profit is: (19 − 0.5P1 − P2)*(P2 - $2).Remember that profit is defined as the difference between the revenue and the cost.
For La Boulangerie we know that they sell Q1 thousand loaves. Each loaf costs $1. Each loaf is sold by P1
Then the profit is just:
P = Q1*(P1 - $1) = (14 − P1 − 0.5*P2)*(P1 - $1)
Which is already written only in terms of P1 and P2.
Similarly, for the other store we will get the profit:
P' = Q2*(P2 - $2) = (19 − 0.5P1 − P2)*(P2 - $2)
Now we must get their best response, which is given by deriving it with respect to the price and making it equal to zero:
For the first store we have:
dP/dP1 = $1 + 14 - 0.52*P2 - 2*P1 = 0
Now we solve it for P1:
P1 = ($1 + 14 - 0.52*P2)/2
Similarly, for the other store we have:
dP'/dP2 = 19 - 0.5*P1 - 2*P2 + $2 = 0
Solving it for P2 it gives:
P2 = (19 - 0.5*P1 + $2)/2
