Charlie runs a book rental business. He currently charges $3 per book and rents out an average of 38 books a day.
According to a study, for every 50C increase in rental price, the average business can expect to lose 4 rentals a day.
Complete the equation that models this scenario, where b(x) is the revenue generated and x is the number of 50 price increases.
b(x)= x + x+ [
Answer:
b(x) = -2X² + 19X + 114
Step-by-step explanation:
b(x) = total revenue generated per day
total revenue formula ⇒ b(x) = price x quantity
price = $3 current price + 0.5X price increase = 3 + 0.5X
quantity = 38 current quantity sold - 4 books per X = 38 - 4X
b(x) = (3 + 0.5X) · (38 - 4X)
b(x) = 114 -12X + 19X - 2X²
b(x) = -2X² + 19X + 114

Determine from the given points of two lines if the lines are parallel, perpendicular, or neither. Enter your answers below. Use a forward slash (i.e. "/') for all fractions (e.g. 1/2 for 1/2 ). o Line a: (3,1) and (8,6) o Line b: (-6,1) and (2,9)
Answer:
lines are parallel
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines is - 1
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = 3, 1) and (x₂, y₂ ) = (8, 6)
m = [tex]\frac{6-1}{8-3}[/tex] = [tex]\frac{5}{5}[/tex] = 1 ← slope of line a
Repeat with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2,9)
m = [tex]\frac{9-1}{2+6}[/tex] = [tex]\frac{8}{8}[/tex] = 1 ← slope of line b
Since both slopes are equal, line a and line b are parallel

Answer:
It's not a function
Step-by-step explanation:
Due to the fact that at one x point there are multiple y values so this cannot be a function. The graph also does not pass the vertical line test, therefore it is not a function.
1. The graph is not represent a function.
2. The table shown in figure is represent a function.
What is Function?
A relation between a set of inputs having one output each is called a function.
Given that;
The graph is shown in shown in figure.
And, In the table;
Value's of x are - 2, 1 , 0 , 2
And values of y are 5, 4 3 , 4
Now,
To check the graph is the function or not, we use vertical line test.
If the vertical line draw parallel to y - axis and it cuts more than one points in the graph, then the graph is not a function.
Here, When we draw a vertical line which is parallel to y - axis then it cuts more than one point, so it is not a function.
Thus, The graph is not represent a function.
2. In the table;
Value's of x (input) are - 2, 1, 0, 2.
And values of y (output) are 5, 4, 3, 4.
Clearly, Every input have exactly one output.
So, By definition of function;
The table shown in figure is represent a function.
Therefore,
1. The graph is not represent a function.
2. The table shown in figure is represent a function.

Answer:
Step-by-step explanation:
-16x+13+-20x+23=180
-36x+36=180
-36x=144
X=-4
Then put -4 in -16(-4) + 13 = 77
Answer is 77
The angle LMP will be 75.22° and the angle NMP will be 104.77°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
∠LMN = ∠ LMP + ∠NMP
Since ∠LMN = 180°
So,
∠ LMP + ∠NMP = 180
-16x + 13 - 20x + 23 = 180
-36x + 40 = 180
36x = -140
x = -3.88
So,
∠ LMP = -16(-3.88) + 13 = 75.22°
So,
∠NMP = 180 - 75.22 = 104.77°
Hence "The angle LMP will be 75.22° and the angle NMP will be 104.77°".

Answer:
$163
Step-by-step explanation:
Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:
26 x 7 = 182
Bob made a total of $182 last month.
Bob then spent $19. Subtract 19 from the total earned:
182 - 19 = 163
Bob has $163 left.
~
Answer:
He has $163 dollars left
Step-by-step explanation:
Because first we needed to find out how much did he make in 26 hours, 29 (hours) x $7 (per hour) = $182
Then he spent $19, $182 (how much he made in 26 hours) - $19 (how much he spent) = $163
