A new auditorium is begging built for a college the balcony has 200 seats the floor has 25 rows with x seats in each row the number of people in the auditorium must be under 750 to meet safety regulations what is the solution of this inequality and what is it's meaning
Question:
A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?
Answer:
[tex]200 + 25x < 750[/tex]
Number of seats in a row must be less than 22
Step-by-step explanation:
Given
Total = Less than 750
Current Seats = 200
Rows = 25
Seat per row = x
Required
Represent as an inequality
The scenario will be represented as:
[tex]Current\ Seats + Rows * x = Total[/tex]
Substitute 200 for Current Seats
[tex]200 + Rows * x = Total[/tex]
Substitute 25 for Rows
[tex]200 + 25* x = Total[/tex]
[tex]200 + 25x = Total[/tex]
Substitute <750 for Total.
The equation then becomes
[tex]200 + 25x < 750[/tex]
Solving further:
[tex]25x < 750 - 200[/tex]
[tex]25x < 550[/tex]
[tex]x < \frac{550}{25}[/tex]
[tex]x < 22[/tex]
This means that:
Number of seats in a row must be less than 22
Find the inverse of the function.
Answer:
The option 'b' is true.
Step-by-step explanation:
Given the expression
[tex]f\left(x\right)=\frac{2}{x+7}[/tex]
A function g is the inverse of the function f if for y=f(x), x=g(y)
[tex]y=\frac{2}{x+7}[/tex]
Replace x with y
[tex]\:x=\frac{2}{y+7}[/tex]
solve for y
[tex]y=\:\:\frac{2}{x}-7[/tex]
Thus,
[tex]f^{-} (x)=\frac{-7x+2}{x}[/tex]
Therefore, option b is true.
An equation of a line can be written in point slope form given any point (_,_) on the line and the slope of the line ___.
Answer:
.... given any point (x,y) on the line and the slope of the line m.
Step-by-step explanation:
Its because a coordinate's variables are (x,y) due it's position on the graph on the x-axis and y-axis; and the slope of the line is called m in general (it's just a mathematical term/variable due to how it is defined in formulas)

Answer:
x = 60
Step-by-step explanation:
These angles are alternate exterior angles because they are on the opposite side of the transversal line and on the outside of a set of two non-transversal lines.
The alternate exterior angles theorem explains that if a pair of non-transversal lines are parallel, then the alternate exterior angles are congruent.
We can use the following equation to solve:
46 = 3x-14
Simplify.
60 = 3x
x= 60

Step-by-step explanation:
Step 1: Subtract 4n from both sides.
3n−2−4n=4n−6−4n
−n−2=−6
Step 2: Add 2 to both sides.

Answer:
It cost $2.50 to rent bowling.each game costs $3.25.you have $22. How many games can you bowl
Answer:
6 games
Step-by-step explanation:
Use the equation 2.5+3.25x=22 to solve in which $2.50 is the initial amount to rent for Bowling, $3.25 the amount of game that is played, $22 for what you have, and x in which is the amount of games you can play at the max. Subtract 2.5 on both sides to get to 3.25x = 19.5. Divide 3.25 on both sides to get your final answer as 6 for your x value in which you can play up to 6 games.
Answer:
6 games
Step-by-step explanation:
you do 2.50 - 22 this you divide 3.25 by what you have left

Answer:
The y-intercept of the function represented in the graph will be: (0, 2)
The graph is also attached.
Step-by-step explanation:
Given the function
[tex]y=3x+2[/tex]
the y-intercept of the function can be determined by setting x=0 and solving for y.
so
[tex]y=3x+2[/tex]
[tex]y=3(0)+2[/tex]
[tex]y=0+2[/tex]
[tex]y=2[/tex]
Thus, the y-intercept of the function represented in the graph will be: (0, 2)

EASY QUESTION- MERRY XMAS
Answer:
The answer will be B.
Step-by-step explanation:
When the number is with the x, it moves the graph in the horizontal direction, and when the number is NOT with the x, it moves the graph in the vertical direction.
So, since -6 is with the x, it is moving the graph Right 6 units. Changing it to 4 units results in the the graph moving 2 units left from 6 units.
The -1 is NOT with the x, so it moves the graph down 1 unit. Taking out the -1 (so putting a 0) results in the graph moving 1 unit up from -1.
So, the graph translated up 1 unit and left 2 units.

In 2005, 120 students at Lincoln High School
had smart phones. By 2010, 345 students in the
same school had smart phones. Which of the
following best describes the annual rate of change
in the number of smart phones students had from
2005 to 2010 at Lincoln High School?
A) The average increase in the number of smart
phones per year is 40.
B) The average increase in the number of smart
phones per year is 45.
C) The average increase in the number of smart
phones per year is 50.
D) The average increase in the number of smart
phones per year is 55.
Answer:
The average increase in the number of smart
phones per year is 45
Step-by-step explanation:
Given that :
Number of students who had phones in 2005 = 120
Number of students who had phones in 2010 = 345
(345 - 120) / 5
225 / 5
= 45
Hence, average increase in number of smartphones per year = 45

9 is subtracted by the sqaure of a number
Answer:
I believe it is x^2-9
Step-by-step explanation:
Since we don't have a specific "number" you use x. It says it's squared to put an exponent of 2. It also says that 9 is subtracted by it so put -9.

Estimate the solution of the equation a(x) = b(x)
IMAGE BELOW
Answer:
The solution of the equation a(x) = b(x) is (9, 5.5)
Step-by-step explanation:
The solution of the system of the linear equations is the common ordered pair in their solutions, this solution is the point of intersection of the lines which represent the two equations graphically
In the given figure
∵ There are two lines, the blue line, and the red line
→ Let the blue line represents a(x) and the red line represents b(x)
∵ The solution of the equation a(x) = b(x) is the point of intersection of
the two lines
∵ The x-coordinate of this point is 9
∵ The y-coordinate of this point is between 5 and 6 (5.5)
∴ The coordinates of the point of intersection are (9, 5.5)
∴ The solution of the equation a(x) = b(x) is (9, 5.5)

Jay has lost his mother’s favorite necklace, so he will rent a metal detector to try to find it. A rental company charges a one time rental fee of $15 plus $2 per hour to rent a metal detector. Jay has only $35 to spend. What is the maximum amount of time he can rent the metal detector?
Answer:
he can rent it for 10 hours
Step-by-step explanation:
35 - 15 = 20
20 divided by 2 equals 10
Answer:
10 hours
Step-by-step explanation:
Say x is the number of hours he can rent the detector at most. Using it, we can set up this equation:
15 + 2x = 35
Subtract 15 from both sides
2x = 20
Divide by 2 on both sides
x = 10
