For the function f defined below, what is the value of f(-1)? fx=x+3<br> -----<br> 2
Pepsi [2]

Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

- 1 =  \frac{x - 3}{ 2}

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

- 2 = x - 3

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

1 = x

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

<h3>(IN THE PICTURE ATTACHED)</h3>

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

<h3>Since the final coordinates are 3/3 and it simplifies, the final answer is 1.</h3>

A house painter has an annual income of $35,000 and paid $2,500 in income tax. What percent of her income is the income tax?
almond37 [142]

Answer:

The 7.14% of her income is the income tax .

Step-by-step explanation:

Formula

Percentage = \frac{Part\ value\times 100}{Total\ value}

As given

A house painter has an annual income of $35,000 and paid $2,500 in income tax.

Here

Part value = $2500

Total value = $35000

Put in the formula

Percentage = \frac{2500\times 100}{35000}

Percentage = \frac{250000}{35000}

Percentage = 7.14\ (Approx)

Therefore the 7.14% of her income is the income tax .
