Fred and Matt are playing basketball. If x represents the points Matt ended with, and 3x represents the points Fred ended with, what does that tell you about the relationship between Matt and Fred’s points?

Answers

It tells you that Fred has three times the score more than Matt.

This is because Matt has x points, Fred tops Matt by 3x points.

Answers

Answer:

y=2/5x-2

Step-by-step explanation:

The main equation you will need for this is y=mx+b

First, you have to find the slope. the equation for that is

-2-0 = -2 (y)

0-5= -5 (x)

A good way to remember this is rise over run or y is always over x

Slope = 2/5 (The negatives cancel out)

The great thing about this is that they have already given you your "y" intercept or "b" which is -2

David has two jobs. He earns $8 per hour babysitting his neighbor's children and he earns $11 per hour working at the coffee shop. If David worked 15 hours at the coffee shop, write an inequality to represent the number of hours, x, babysitting that David will need to work to earn a minimum of $200. Use the inequality to find the number of full hours he must babysit to reach his goal of $200.

Answers

Answer:

The number of full hours he must babysit to reach his goal of $200 is 5 hours

Step-by-step explanation:

Let x be the no. of hours he must babysit to reach his goal of $200.

Cost for working 1 hour at coffee shop = $11

Cost for working 15 hour at coffee shop = [tex]11 \times 15=165[/tex]

Cost for working 1 hour babysitting = $8

Cost for working x hour babysitting = 8x

We are supposed to find the number of full hours he must babysit to reach his goal of $200.

165+8x=200

8x=200-165

[tex]x=\frac{200-165}{8}[/tex]

x=4.375

Hence The number of full hours he must babysit to reach his goal of $200 is 5 hours

Answers

Answer:

1. [tex]x[/tex] = 9

2. [tex]h[/tex] = 2

3. Infinitely Many Solutions

4. No solution

Step-by-step explanation:

Hey there! I will give the following steps, if you have any questions feel free to ask me in the comments below.

1.) 5(2[tex]x[/tex] + 6) = 8[tex]x[/tex] + 48

Step 1: Expand.

10[tex]x[/tex] + 30 = 8

Step 2: Subtract 30 from both sides.

10[tex]x[/tex] = 8

Step 3: Simplify 8[tex]x[/tex] + 48 − 30 to 8[tex]x[/tex] + 18.

10[tex]x[/tex] = 8

Step 4: Subtract 8[tex]x[/tex] from both sides.

10[tex]x[/tex] − 8

Step 5: Simplify 10[tex]x[/tex] − 8[tex]x[/tex] to 2[tex]x[/tex].

2[tex]x[/tex] = 18

Step 6: Simplify [tex]\frac{18}{2}[/tex] to 9.

[tex]x[/tex] = 9

2.) −3(8 + 3[tex]h[/tex]) = 5[tex]h[/tex] + 4

Step 1: Expand.

−24 − 9[tex]h[/tex] = 5

Step 2: Add 24 to both sides.

−9[tex]h[/tex] = 5

Step 3: Simplify 5[tex]h[/tex] + 4 + 24 to 5[tex]h[/tex] + 28.

−9[tex]h[/tex] = 5

Step 4: Subtract 5[tex]h[/tex] from both sides.

−9[tex]h[/tex] − 5

Step 5: Simplify −9[tex]h[/tex] − 5[tex]h[/tex] to −14[tex]h[/tex].

−14[tex]h[/tex] = 28

Step 6: Divide both sides by −14.

[tex]h[/tex] = [tex]-\frac{28}{14}[/tex]

Step 7: Simplify [tex]\frac{28}{14}[/tex] to 2.

[tex]h[/tex] = 2

3.) 2([tex]y[/tex] − 6) = 3([tex]y[/tex] − 4) − [tex]y[/tex]

Step 1: Expand.

2[tex]y[/tex] − 12 = 3

Step 2: Simplify 3[tex]y[/tex] − 12 − [tex]y[/tex] to 2[tex]y[/tex] − 12.

2[tex]y[/tex] − 12 = 2 − 12

Step 3: Since both sides equal, there are infinitely many solutions.

Infinitely Many Solutions

4.) 8[tex]x[/tex] − 4 = 2(4[tex]x[/tex] − 4)

Step 1: Expand.

8[tex]x[/tex] − 4 = 8

Step 2: Cancel 8[tex]x[/tex] on both sides.

−4 = −8

Step 3: Since −4 = −8 − 4 = −8 is false, there is no solution.

No solution

f(x) =2x-4 and g(x) =-3x+2 find: f(g(x))

Answers

Answer:

[tex]f(g(x))=-6x[/tex]

Step-by-step explanation:

Composite Function

Given f(x) and g(x) as real functions, the composite function named [tex](f\circ g)(x)[/tex] is defined as:

[tex](f\circ g)(x)=f(g(x))[/tex]

It can simply be found by substituting g into f.

Our functions are:

[tex]f(x)=2x-4[/tex]

[tex]g(x)=-3x+2[/tex]

Substituting g into f:

[tex]f(g(x))=2(-3x+2)-4[/tex]

Operating:

[tex]f(g(x))=-6x+4-4[/tex]

Simplifying:

[tex]\boxed{f(g(x))=-6x}[/tex]

The final price includes the original price paid plus an expected capital gain. The actions of the marginal investor determine the equilibrium stock price. Market equilibrium occurs when the stock's price is -Select-less thanequal togreater thanCorrect 1 of Item 1 its intrinsic value. If the stock market is reasonably efficient, differences between the stock price and intrinsic value should not be very large and they should not persist for very long. When investing in common stocks, an investor's goal is to purchase stocks that are undervalued (the price is -Select-abovebelowequivalent toCorrect 2 of Item 1 the stock's intrinsic value) and avoid stocks that are overvalued.The value of a stock today can be calculated as the present value of -Select-a finitean infiniteCorrect 3 of Item 1 stream of dividends:This is the generalized stock valuation model. We will now look at 3 different situations where we can adapt this generalized model to each of these situations to determine a stock's intrinsic value:1. Constant Growth Stocks;2. Zero Growth Stocks;3. Nonconstant Growth Stocks.Constant Growth Stocks:For many companies it is reasonable to predict that dividends will grow at a constant rate, so we can rewrite the generalized model as follows:This is known as the constant growth model or Gordon model, named after Myron J. Gordon who developed and popularized it. There are several conditions that must exist before this equation can be used. First, the required rate of return, rs, must be greater than the long-run growth rate, g. Second, the constant growth model is not appropriate unless a company's growth rate is expected to remain constant in the future. This condition almost never holds for -Select-maturestart-upCorrect 4 of Item 1 firms, but it does exist for many -Select-maturestart-upCorrect 5 of Item 1 companies.Which of the following assumptions would cause the constant growth stock valuation model to be invalid?The growth rate is zero.The growth rate is negative.The required rate of return is greater than the growth rate.The required rate of return is more than 50%.None of the above assumptions would invalidate the model.-Select-Statement aStatement bStatement cStatement dStatement eCorrect 6 of Item 1Quantitative Problem 1: Hubbard Industries just paid a common dividend, D0, of $1.60.

Do not round intermediate calculations.$ per shareZero Growth Stocks:The constant growth model is sufficiently general to handle the case of a zero growth stock, where the dividend is expected to remain constant over time. In this situation, the equation is:Note that this is the same equation developed in Chapter 5 to value a perpetuity, and it is the same equation used to value a perpetual preferred stock that entitles its owners to regular, fixed dividend payments in perpetuity. The valuation equation is simply the current dividend divided by the required rate of return.Quantitative Problem 2: Carlysle Corporation has perpetual preferred stock outstanding that pays a constant annual dividend of $2.00 at the end of each year. If investors require an 10% return on the preferred stock, what is the price of the firm's perpetual preferred stock? Round your answer to the nearest cent. Do not round intermediate calculations.$ per shareNonconstant Growth Stocks:For many companies, it is not appropriate to assume that dividends will grow at a constant rate. Most firms go through life cycles where they experience different growth rates during different parts of the cycle. For valuing these firms, the generalized valuation and the constant growth equations are combined to arrive at the nonconstant growth valuation equation:Basically, this equation calculates the present value of dividends received during the nonconstant growth period and the present value of the stock's horizon value, which is the value at the horizon date of all dividends expected thereafter.Quantitative Problem 3: Assume today is December 31, 2013. Imagine Works Inc. just paid a dividend of $1.15 per share at the end of 2013. The dividend is expected to grow at 15% per year for 3 years, after which time it is expected to grow at a constant rate of 6% annually. The company's cost of equity (rs) is 9.5%.
