If a kayak rental shop rents 28 kayaks per week when it charges $25 per day. For each $5 increase in price, the shop loses four kayak rentals per week. 720 is the maximum weekly revenue
What is Equation?Two or more expressions with an Equal sign is called as Equation.
It is given that a kayak rental shop rents 28 kayaks per week when it charges $25 per day
For each $5 increase in price, the shop loses four kayak rentals per week. we need to find How much should the kayak rental shop charge to maximize weekly revenue
R(x)=(25+5x)(28-4x)
=5(5+x)4(7-x)
=20(5+x)(7-x)
=-20(5+x)(x-7)
when x=1 it is maximum
Price when x =1 is 25+5(1)=30
To calculate maximize revenue
R(1)=(25+5)(28-4)
=30(24)
=720
Hence the maximum weekly revenue is $720.

The cost of 4 books is $18.00 and the cost of 4 pens is $20.00. Find the cost of six similar
books and six similar pens.
Answers
18/4 is 4.5
$4.50 per book
4 pens is 20.00
20/4 is 5
$5.00 per pen
6 books $4.50 each
6(4.50) = $27
6 pens $5.00 each
6(5) = $30
6 books is $27
6 pens is $30
4 books = $18 so divide 18 by 2 get 9 so 2 books are $9 just add $18 to $9 to get $27
4 pens = $20 so divide 20 by 2 get 10 so 2 pens = $10 just add $20 to $10 to get $30

Given table:
x | -2, 2, 6, 10 y | 3, -9, -21, -33Use two pairs of points to work out the equation of the line y = mx + b:
(-2, 3) and (2, - 9)Find the slope:
m = (-9 - 3)/(2 - (-2)) = - 12/4 = - 3Use one pair to find the y-intercept:
3 = - 3*(-2) + b3 = 6 + bb = 3 - 6b = - 3The line is:
y = - 3x - 3m = (-9 - 3)/(2 + 2) = -12/4 = -3 ==> (x)
3 = (-3)•(-2) + b
3 = 3•2 + b
3 = 6 + b

Step-by-step explanation:
h + 5f = 8.74 → (1)
2h + 3f = 7.75 → (2)
Multiplying (1) by 3 and (2) by - 5 and adding will eliminate f
3h + 15f = 26.22 → (3)
- 10h - 15f = - 38.75 → (4)
Add (3) and (4) term by term to eliminate f

Answer:
Step-by-step explanation: We can solve this in two ways: Solve the equations directly, or graph the lines and find the point they intersect (which will be the only point at which they are equal.
Solve The Equations:
y = 2x+9
y = -x-3
Set them equal to each other (to find x such that both equations will return the same value for y).
-x-3 = 2x + 9
-3x = 12
x = -4
Use x=-4 in either equation to find y:
y = -x-3
y = -(-4)-3
y = 1
===
The point is (-4,1). That is the point that satisfies both equations:
1) y = 2x+9
y = 2(-4)+9
y = 1, and
2) y = -x-3
y = -(-4)-3
y = 1
=====
We can also solve by graphing and finding the point at which the two lines intersect. A graph is attached.

Someone could help me with problem 3-75 (b) please
Answers
Answer:
a. is correct
b. not correct
c. not correct
d. is correct
Step-by-step explanation:
3-75:
a) 3x + 7 = x - 1
Subtract 7 on both sides to get 3x = x - 8, then subtract x from 3x to get 2x = -8, finally divide 2 on both sides to get x = -4. (Answer is yes)
b) -2x - 4 = -4x + 3
Add 4 on both sides to get -2x = -4x + 7, then add 4x to -2x to get 2x = 7, finally divide 2 on both sides to get x = 7/2. (Answer is no)
c) -3x + 5 + 5x - 1 = 0
Add 1 on both sides to get -3x + 5 + 5x = 1, then subtract 5 on both sides to get -3x + 5x = -4, next combine -3x and 5x together to get 2x = -4, finally divide 2 on both sides to get x = -2. (Answer is no)
d) -(x - 1) = 4x - 5 - 3x
Combine 4x and -3x together to get
-(x - 1) = x - 5, then add (x - 1) and (x - 5) together to get 2x - 6, next do 2x - 6 = 0 and solve for x, by adding 6 on both sides to get 2x = 6, and finally dividing 2 on both sides to get x = 3. (Answer is yes)
