Answer:
C=0.15y+7.89
Step-by-step explanation:
The linear equation represents the cost C of a movie ticket y is C=0.15y+7.89. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
What is meant by linear equation?A linear equation is an algebraic equation of the form y=mx + b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
We define a linear equation. Equations of degree 1 are linear equations. It is the straight line's equation. A linear equation with parameters a and b equal to zero has the conventional form ax+by+c = 0.
When two linear expressions are equal, there is a linear equation in one variable. Or, to put it another way, a graph would be one method of solving this equation.
Given ,
Average price of movie ticket =$7.89
Increased average tickets =$0.15
So Simplifying the equation is
C=0.15y+7.89
Therefore The linear equation represents the cost C of a movie ticket y is C=0.15y+7.89.

the area of a face of a cube is 144cm^2 . find its volume
Step-by-step explanation:
1 face area = length x width (aka length x length since cube)
therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)
volume = length x width x height = 12 x 12 x 12 = 1728cm^3

Bradly can earn extra money by mowing lawns. His neighbors will pay him 3.00 for each lawn that takes him 3/4 of an hour. What is the amount of time in extra hours, that Bradley would have to spend mowing lawns to be able to buy a second $48 ticket for his brother.
Time for which Bradly has to mow lawns to get $48:
We know that Bradly earn $3 every 3/4 hours of mowing lawns
Time taken by Bradly to get $1:
time taken by Bradly to get $1 = time taken to get $3 / $3
time taken = (3/4) / 3
time taken = 1/4 hours / dollar
Time taken by Bradly to get $48:
Time taken to get $48 = time taken to get $1 * 48
Time taken to get $48 = 1/4 * 48
Time taken = 12 hours
Therefore, after 12 hours of Mowing lawns, Bradly will have $48

A function, f(x), represents the distance a car travels over time. The line tangent to the function at x=1 is y=0.6x+0.9. The line tangent to the function at x=4 is y=2.1x-3.2. The line tangent to the function at x=6 is y=4.6x-16.3.
9514 1404 393
Answer:
0.6
Step-by-step explanation:
The instantaneous rate of change at any point on a curve is the slope of the tangent line at that point.
At x=1, the tangent line is given as ...
y = 0.6x +0.9
The slope of that line is the coefficient of x, 0.6.
The instantaneous rate of change of f(x) at x=1 is 0.6.

A charter airline finds that on its Saturday flights from Philadelphia to London all 180 seats will be sold if the ticket price is $200. However, for each $3 increase in ticket price, the number of seats sold decreases by one. (a) Find a formula for the number of seats sold S if the ticket price is P dollars.
Answer:
[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]
Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.
[tex]S\propto P[/tex]
It can be written as:
[tex]S = kP+C[/tex]
Where [tex]k[/tex] is the constant of proportionality and
[tex]C[/tex] is a constant.
Now, putting the given values:
[tex]180 = 200k +C ..... (1)[/tex]
[tex]179 = 203k+C[/tex] ...... (2)
Subtracting (1) from (2):
[tex]3k = -1\\\Rightarrow k =-\dfrac{1}{3}[/tex]
Putting the value in (1):
[tex]\Rightarrow C = 180+\dfrac{200}{3} = \dfrac{740}{3}[/tex]
Therefore the equation becomes:
[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]

Colton's Gym charges an initiation fee of
$40 plus a monthly fee of $50. Which
of the equations below shows the cost
c of joining the gym for m months?
O c = 50 + 40m
O c = 40 + 50m
C + 40 - 50m
Answer:
c = 40 + 50m
Step-by-step explanation:
40 is a constant, it is not affected by the number of months the person works out at the gym for.
There is a monthly fee of $50. So, every month Colton gets charged $50, so this is the variable.
The total cost would be represented by the equation c = 40 + 50m then.
Let's look at this using a number for m.
If Colton went to the gym for 2 months then we can set up the equation like this:
c = 40 + 50(2)
c = 40 + 100
c = 140
Therefore he spends a total of $140 for 2 months.

1/2 of 66: 1/2 x 66 = 33
Can someone show an example of Inverses of Functions
Because I do not understand that subject
Answer:
I believe you mean algebra and inverses when you change it to solve inequalities.
Step-by-step explanation:
Let's use -3 + 4 as an example. In order to change the function, you will switch the sign. (In this case, we change "+" into ")
At this same time, you must change the sign in front of the numbers. (Positive signs become negative and negative signs become positive.
So, -3 + 4 is the same thing as 3 - -4.
3 - 4 = -1
-3 + 4 = 1
Tip: When subtracting a negative number, the answer is likely to go up instead of down.

BRAINLIEST WILL BE MARKE FOR THE BEST ANSWER GIVEN
Answer: Yes
Step-by-step explanation:
The Vertical angle would show that 2 of the angles are exactly the same. Its also given 2 lines that are marked as congurent. Since we know that angle and the lines are congruent we can also say that angle IFJ is congruent to angle IHG meaning that they are congruent because of ASA (Angle Side Angle Theorem)
Congruent triangles have equal corresponding sides lengths and angle measures.
The triangles are congruent by ASA
From the attached figure, we have:
[tex]\mathbf{HI \cong IF}[/tex]
Lines HG and JF are parallel lines.
It means that:
Angles G and F are corresponding, and also angles at I in both triangles are vertical angles.

Based on 20 samples, the average resistance is 25 ohms and the sample standard deviation is 0.5 ohm. Determine the 90% confidence interval of the standard deviation of the batch. (10 points)
Answer:
90% Confidence Interval = [24.81, 25.19]
Step-by-step explanation:
From the question, our number of samples is 20, it is small because it is less than 30. Hence we use the t score confidence interval formula
= Mean ± t score × Standard deviation/√n
Mean = 25 ohms
Standard deviation = 0.5 ohms
n = 20
We find the degrees of freedom = n - 1
= 20 - 1 = 19
Using the T score table
T score for 90% confidence interval with degrees of freedom 19
= 1.729
Hence:
Confidence Interval =
= 25 ± 1.729 × 0.5/√20
= 25 ± 0.1933080767
=
Confidence Interval
25 - 0.1933080767
= 24.806691923
≈ 24.81
25 + 0.1933080767
= 25.1933080767
≈ 25.19
90% Confidence Interval = [24.81, 25.19]

Answer:
11
Step-by-step explanation:
Given that:
Two adjacent terms of an arithmetic sequence are given as 5, 8.
To find:
The next term = ?
Solution:
First of all, let us learn about an arithmetic sequence and its property.
An Arithmetic sequence (sometimes known as Arithmetic Progression or an AP), is a sequence in which there is a common difference between every two terms.
Suppose, an arithmetic sequence is:
[tex]a, b, c, d[/tex]
Then common difference = [tex]b-a=c-b=d-c[/tex]
Let the next term in the given sequence be [tex]x[/tex].
Then as per the property of an Arithmetic sequence, we can say:
[tex]8-5=x-8\\\Rightarrow x=3+8\\\Rightarrow x =\bold{11}[/tex]
Therefore, the answer is: 11
If 1/2 cup of white sugar is needed for one batch of oatmeal raisin cookies, how much white sugar is needed for 8 batches of cookies?
Answer:
4 cups
Step-by-step explanation:
For one batch of cookies you'll need 1/2 cup of sugar. 8 batches of cookies is 8 times the amount of batches of one batch of cookies. So, if the amount of batches is multiplied by 8, then we need to multiply the amount of sugar by 8 as well:
1/2 * 8 = 8/2 = 4/1 = 4
4 cups of white sugar are needed for 8 batches of cookies.
