Answers

Answer:

f-1(x)=x-4

f-1(4)=0

Step-by-step explanation:

to get an inverse function, replace x with y, and y with x.

y=x+4  ---> x=y+4

solve for y: x=y+4 --> y=x-4 --> f-1(x)=x-4

f-1(4)=(4)-4=0

Ken went to a county fair and spent $5 on admission, $6.50 on games, and $7.21 on food. If he had $30 before he went to the fair, how much money does he have left?

A system of equations is shown below:

2x = 5y + 4
3x − 2y = −16

What is the solution to this system of equations? (5 points)

Answers

Answer:

x = -8, y = -4

Step-by-step explanation:

First we want to write the equations so the variables line up

[tex]2x - 5y = 4\\3x - 2y = -16\\[/tex]

Next, we could either multiply one of the equations to cancel out the x's or the y's, either one works.

I will choose to cancel out the x's

[tex]-3R_1 + 2R_2\\-6x + 15y = -12\\6x - 4y = -32[/tex]

add the equations and solve

[tex]11y = -44\\y = -4[/tex]

once you have one variable, you can use it to solve the other

[tex]2x - 5(-4) = 4\\2x + 20 = 4\\2x = -16\\x = -8[/tex]

verify

[tex]3(-8) - 2(-4)\\-24+ 8\\-16\\[/tex]

it works

So the answer is
X = -8
Y = -4
Here is the working

A graph has height (inches) on the x-axis and arm span (inches) on the y-axis. Points are at (30, 27), (45, 45), (53, 50), (60, 60), (67, 70), and (73, 72).

Identify if there is a relationship between the variables.
(A) No, there is no relationship because the points are all up and down.
(B) Yes, the relationship displayed shows arm span increasing as height increases.
(C) Yes, the relationship displayed shows arm span decreasing as height increases.

Larry spends a total of 45 minutes running. He begins at a pace of 8 miles per hour and then reduces his speed to 5 miles per hour. Let t represent the number of minutes Larry spent running at the faster pace. Larry models his distance with the expression 8t+5(45−t) to model the situation. Did Larry correctly model the situation

Answers

Answer:

Yes, he did

Step-by-step explanation:

We have that:.

Total time = 45

At time t, he moves at 8mph.

This gives: 8t

The time left is: 45 - t and he moves at 5mph, this gives 5(45 - t).

Hence, the total is

8t + 5(45 - t)

By comparison, we can conclude that Larry modeled the situation correctly.

A 42​-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first​ piece, and the third piece is Two inches more than seven times the length of the first piece. Find the lengths of the pieces.

Answers

Answer:

4, 8, 30

Step-by-step explanation:

Let's call the first piece x. If the first piece is x, then the second piece is 2x and the third piece is 7x + 2.

Equation:

x + 2x + 7x + 2 = 42

10x + 2 = 42

10x = 40

x = 4

The First piece is 4 inches

Now all we do is substitute the x for 4. Therefore, the second piece is 8 inches and the third piece is 30.

what is the equation in slope intercept form 6x-4y=12 ?​

Answers

Answer:

y=6/4x-3

Step-by-step explanation:

First, you isolate the y, by subtracting 6x from each side. Then, you divide by -4 on both sides to isolate it to an individual y.

Answer:

Slope = 6/4 or 1 1/2

Step-by-step explanation:

Step 1:

6x - 4y = 12       Equation

Step 2:

y = mx + b       Slope Intercept Form

Step 3:

- 4y = - 6x + 12      Subtract 6x on both sides

Step 4:

y = 6/4x + 12        Divide 4 on both sides

Answer:

Slope = 6/4 or 1 1/2

A group of local organizers, led by a prominent local businesswoman, would like to use the pavilion for a concert to benefit a non-profit, national network of investors and environmental organizations working with companies and investors to address sustainability challenges such as global climate change. If the pavilion management agrees to host the concert, the organizers will donate all profits to Ceres (or absorb any losses).Based on the following revenue and cost information, the organizers would like answers to several questions.1. There are three sources of revenue for the concert:2. Tickets will be sold for $15.50 each.3. A large multinational corporation headquartered in Chicago will donate $2.00 per ticket sold.4. Each concert attendee is expected to spend an average of $17.00 for parking, food, and merchandise.5. On the expense side, there are also three components:A popular national group has agreed to perform at the concert. Normally, the group demands a significant fixed fee to perform, but to reduce the risk for the organizers, the group has agreed to perform for $6.00 per ticket sold. The organizers will pay several companies to operate the parking, food, and merchandise concessions. They will pay $21,000 plus 15% of all parking, food, and merchandise revenue. The organizers will pay the pavilion $85,000 plus $7.00 per person attending to cover its operating expenses (production, maintenance, advertising, etc.)Required:a.
