Answer:   d)  f(x) = | x - 2 | + 1

<u>Step-by-step explanation:</u>

Input the first coordinate (-2, 5) into each of the equations to see which makes a true statement.

f(x) = | x | + 1

5  = | -2 | + 1   →   5 = 2 + 1   →   5 = 3   FALSE

f(x) = | x - 2 |

5  = | -2 - 2 |    →   5 = | 4 |   →   5 = 4   FALSE

f(x) = | x - 2| - 1

5  = | -2 - 2 | - 1   →   5 = | 4 | - 1   →   5 = 3   FALSE

f(x) = | x - 2| + 1

5  = | -2 - 2 | + 1   →   5 = | 4 | + 1   →   5 = 5   TRUE!

Pani-rosa [81]

Answer:

Yes, this is a valid inference because she took a random sample of the neighborhood.

Step-by-step explanation:

As we can see, Sue's survey was perfectly random and without any prejudice.

18% of the families, according to her research, would volunteer at the shelter. According to her, 18% of the local households should be required to volunteer at the animal shelter.

Talja [164]

Answer:

There will be $5624.32 in the account after 3 years if the interest is compounded annually.

There will be $5630.812 in the account after 3 years if the interest is compounded semi-annually.

There will be $5634.125 in the account after 3 years if the interest is compounded quarterly.

There will be $5636.359 in the account after 3 years if the interest is compounded monthly

Step-by-step explanation:

Tamira invests $5,000 in an account

Rate of interest = 4%

Time = 3 years

Case 1:

Principal = 5000

Rate of interest = 4%

Time = 3 years

No. of compounds per year = 1

Formula :A=P(1+r)^t

A=5000(1+0.04)^3

A=5624.32

There will be $5624.32 in the account after 3 years if the interest is compounded annually.

Case 2:

Principal = 5000

Rate of interest = 4%

Time = 3 years

No. of compounds per year = 2

Formula : A=P(1+\frac{r}{n})^{nt}

A=5000(1+\frac{0.04}{2})^{2 \times 3}

A=5630.812

There will be $5630.812 in the account after 3 years if the interest is compounded semi-annually.

Case 3:

Principal = 5000

Rate of interest = 4%

Time = 3 years

No. of compounds per year = 4

Formula : A=P(1+\frac{r}{n})^{nt}

A=5000(1+\frac{0.04}{4})^{4 \times 3}

A=5634.125

There will be $5634.125 in the account after 3 years if the interest is compounded quarterly.

Case 4:

Principal = 5000

Rate of interest = 4%

Time = 3 years

No. of compounds per year = 4

Formula :A=P(1+\frac{r}{n})^{nt}

A=5000(1+\frac{0.04}{12})^{12 \times 3}

A=5636.359

There will be $5636.359 in the account after 3 years if the interest is compounded monthly

Step-by-step explanation:

Remember:

m = \frac{y_2 - y_1 }{x_2 - x_1}

Let's plug in!

m = \frac{ 9 - 4}{4 - ( -1)} = \frac{ 5}{ 5} = 1
