Answer:

11

Step-by-step explanation:

Plug in 1 to the function:

f(x) = 6x + 5

f(1) = 6(1) + 5

f(1) = 6 + 5

f(1) = 11

⇒Option A is an expression of a difference 7 and 5x which is the product of 5 and x.

⇒Option A is the  answer.

The lower limit of the 95% confidence interval for the average miles per gallon is 23.32 mpg.

How to calculate the lower limit of the confidence interval?

Given,

n = 30

mean = μ = 24.1

standard deviation = σ = 2.1

confidence interval = 95%

Since the sample is 30, use t-table. If sample is greater than 30 use z-table.

Level of significance, α = 1 - 0.95 = 0.05

degree of freedom, df = n - 1 = 30 - 1 = 29

t value = 2.045

Lower limit = [tex]\mu-t\frac{s}{\sqrt{n}}[/tex]

= [tex]24.1 - 2.045\frac{2.1}{\sqrt{30}}[/tex]

= 24.1 - 0.784

= 23.316

= 23.32 mpg

Thus, the lower limit of the 95% confidence interval for the average miles per gallon is 23.32 mpg.

Answer: 50x+200=y

Step-by-step explanation:

This is the answer because the number of hours is not provided leaving us to multiply 50 by x, 200 is the flat fee so we will know to automatically add that to our first step and since y is the total this will form the equation, 50x+200=y.

Answer:

Line CE

Step-by-step explanation:

We know that lines are perpendicular when their intersections form 90° angles (see below diagram). ∠E is a 90° angle, so line CE is perpendicular to line DF. Assuming that line DF is parallel to line AB, we now know that line CE is also perpendicular to line AB.

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values.These letters are called variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

If the number is represented by x then,

1x/5+3x= 2x+42

making the left hand side a single fraction, then,

(x+15x)/5= 2x+42

16x/5= 2x+42

multiply both sides by 5

16x= 10x+210

Using simplification, if the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.

From the given question,

We know that the capacity of movie theater is 183.

The theater charges $5.00 for children, $7.00 for students and $12.00 of adults.

There are half as many adults as there are children.

If the total ticket sales was $1316, then we have to find how many children, students, and adults attended.

Let the number of children that attended = x

Since, there are half as many adults as children.

Therefore number of adults = 1/2x =0.5x

We know there are total of 183 tickets

Therefore number of students = 183 - x - 0.5x

number of students = 183 - 1.5x

Each children ticket costs = $5

Then the price of children tickets = 5x

Similarly for adults each ticket costs = $12

So total cost of adult ticket = 12×0.5x = $6x

Now the cost of student tickets = 7(183 - 1.5x)

As given that

Total cost of all tickets = $1316

So the expression should be

5x + 6x + 7(183 -1.5x) = 1316

Simplifying

11x + 1281 - 10.5x = 1316

Subtract 1281 on both side

11x + 1281 - 10.5x-1281 = 1316-1281

Simplifying

0.5x = 35

Divide by 0.5 on both side we get

x = 70 children

Now finding the number of adults

= 0.5x

= 0.5×70

= 35 adults

Now finding the number of students

= 183 - 1.5x

= 183 - 1.5×70

= 183 - 105

= 78 students

Hence, If the total ticket sales was $1316, then 70 children, 78 students and 35 students attended.

Answer:

63 inches

Step-by-step explanation:

The perimeter of a rectangle is found by adding all of the side lengths. Since both pairs of opposite sides have the same length, an equation for the perimeter can be written like this:

[tex]P=2w+2l[/tex]

Where w and l represent the width and length.

Since we are asked to find the length, rewrite the equation in terms of l:

[tex]l=\frac{P-2w}{2}[/tex]

We know the values for P and w, so plug those in:

[tex]l=\frac{150-2(12)}{2}[/tex]

Now simplify!

[tex]l=\frac{126}{2}=63[/tex]

Answer:

l = 63 in  

Step-by-step explanation: If the P=150 in  W=12 in so .... using the formula P=2 (l + w) you get  L= P/2 - W = 150/2 - 12 = 63 in. I hope this helps!

Subways Franchise operate 16 submarine sandwich shop and they expanded quickly with its long time slogan "East Fresh".

Franchisor gives a franchisee the authority to do business in the franchisor's trade name using its business system it is called franchising.

Subways franchises pay 12.5% every week (gross sales minus the sales tax), 8% goes toward the franchise royalties and 45% gores towards advertising.

The company has the lowest start-up costs compared to many other fast food franchises but does take more royalty and advertising money.

The franchise fee:

Now, according to the question:

Total number of subway franchisees = 42,000

Average annual store revenue = $417,000

Total paying percentage of franchisees = 12.5%

∴ At 12.5% of average revenue = (417000 × 12.5) ÷ 100

                                                    = $52,125

The equation of the line that passes through (-1, -1) and is parallel to x + y = 8 is x + y = -2

The equation of the line that passes through (-5, -2) and is parallel to y + 3x = 10 is 3x + y = -17

From the question, we are to determine the equation of the line passing through the given points and parallel to the given line.

NOTE: If two lines are parallel, then their slopes are equal

First, we will determine the slopes of the given line

x + y = 8

Write the equation in the slope-intercept form, y = mx + b

Where m is the slope

and b is the y-intercept

x + y = 8 becomes

y = -x + 8

Therefore, m = -1

Now, we will determine the equation of a line that has a slope of -1 and that passes through (-1, -1)

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

y - (-1) = -1(x - (-1))

y + 1 = -1(x + 1)

y + 1 = -x -1

x + y = -1 -1

x + y = -2

Hence, the equation is x + y = -2

Now, we will determine the slope of y + 3x = 10

Express the equation in slope-intercept form

y + 3x = 10

y = -3x + 10

Therefore, m = -3

Now, we will determine the equation of a line that has a slope of -3 and that passes through (-5, -2)

Using the point-slope form of the equation of a straight line,

y - y₁ = m(x - x₁)

y - (-2) = -3(x - (-5))

y + 2 = -3(x + 5)

y + 2 = -3x - 15

3x + y = -15 -2

3x + y = -17

Hence, the equation is 3x + y = -17

3. 5 hours

Step-by-step explanation:

We can solve all of these problems using algebraic equations.

1. In this question, we will use variable x to represent the age of Mrs. Olsen's daughter.

In 10 years, x - 20 = 2x. That means that in 10 years, Mrs. Olsen will be 40 years old. That means she is 30 right now.

2. In this question, we will use variable x to represent the age of Alyssa.

If, in 30 years, their total age is 88, their current total is 28. Tyler is 3 times as old as Alyssa, so Tyler is 21 and Alyssa is 7.

3. Ryan leaves home at 50 mph. That means, in an hour Ryan will be 50 miles away from home. At that point, Jacob leaves home at a speed of 60 mph, so the gap between them closes by 10 miles each hour. That means that Jacob will take 5 hours to catch up, counting from when he left (how far is this workplace jeez?!?!?!?).

We could also represent this with a graph.

Hour 1: R = 50, J = 0 (Jacob leaves after this hour so it doesn't count for the answer)

Hour 2: R = 100, J = 60

Hour 3: R = 150, J = 120
