Answer:

Subtract 5x

Step-by-step explanation:

Cause then you would only get one x in the equation instead of 6x and 5x. Hope this helps!

Analyze the key features of the graph of f(x) shown below. Use rules of transformations and the parent function to formulate an

sweet [91]

Answer:

The required equation is $f(x)=\frac{1}{x+3}-2$ .

Step-by-step explanation:

The parent function of a rational function is

$g(x)=\frac{1}{x}$

The transformation is defined by the function

$f(x)=\frac{1}{x+a}+b$

Where, a represents the horizontal shift and b represents the vertical shift.

If a>0, then graph of parent function will shift left side and if a<0, then graph of parent function will shift right side.

If b>0, then graph of parent function will shift upward and if b<0, then graph of parent function will shift downward side.

Since the graph of parent function shifts 3 units left and 2 units down. Therefore the value of a is 3 and the value of b is -2.

The new function is

$f(x)=\frac{1}{x+3}-2$

Therefore the required equation is $f(x)=\frac{1}{x+3}-2$ .

A store sells flower arrangements at a cost of $28 each. Which statements are true regarding the price of the arrangements? Sele

SashulF [63]

Answer:

10%=$25.20

25%=$21.00

35%=$18.20

Step-by-step explanation:

A mark-down in price of 10% is the same as 90% of the original price. 90% can be expressed as 0.9. $28.00(0.9)=$25.20. This same explanation holds true for the 25%/35% mark-down: $28.00(1-0.25)=$21.00; $28.00(1-0.35)=$18.20. Additionally, if you try this with the 40%/50% mark-downs it doesn‘t work.

Based on past experience, a bank believes that 13% of the people who receive loans will not make payments on time. The bank has

g100num [7]

Answer:

The sample proportion mean and standard deviation are

$\mu=p=0.13\\\\\sigma=\sqrt{\frac{p(1-p)}{N} }= \sqrt{\frac{0.13*0.87}{500} }=0.015$

With reasonable assumptions about the sample, all the conditions are met.

The probability that over 16% of these clients will not make timely payments is P=0.023.

Step-by-step explanation:

We have a sample of 500 loans, of which a proportion of p=0.13 is expected to not be paid on time.

The sample proportion mean and standard deviation are

$\mu=p=0.13\\\\\sigma=\sqrt{\frac{p(1-p)}{N} }= \sqrt{\frac{0.13*0.87}{500} }=0.015$

The assumptions underlying this model are:

- The sample is randomly selected from the population.

- The sampling distribution of p-hat is approximately normal. There are at least 10 successes and 10 failures in the sample.

- Individual observations are independent of each other.

With reasonable assumptions about the sample, all the conditions are met.

What is the probability that over 16% of these clients will not make timely payments?

$z=\frac{x-\mu}{\sigma} =\frac{0.16-0.13}{0.015}=\frac{0.03}{0.015}=2\\\\P(p>0.16)=P(z>2)=0.023$

The probability that over 16% of these clients will not make timely payments is P=0.023.

X : y = 5 : 3 and x + y = 56 Work out the value of x - y

Otrada [13]

Answer:

Step-by-step explanation:

x / y = 5 / 3, then 3x = 5y , x = 5/3y

we can type 5/3y instead of x ;

5/3y + y = 8/3y = 56, then y = 21

now let's find x ;

x - 21 = 56, then x = 35

x - y = 35 - 21 = 14
