7 students borrow the notebook computers if

(a) each student can borrow at most one notebook computer?

(b) there are no restrictions?

Answer:

**Answer:**

a, 7C5 = 21 ways

b, 11C5 = 462 ways

Simplify the expression by combining like terms.15 + 12x – 5x + 4y - 7(A) 11xy + 8(B) 7x + 4y + 8(C) 7x + 4y - 7(D) 15 + 11xy - 7

i think the answer is 12. there is 2 pints in a quart and 1 pint is 2 cups.

Steps:

1. Multiply the -2 by x which equals -2x

2. Multiply -2 by 5 which equals -10

3. Your answer is -2x + -10

1. Multiply the -2 by x which equals -2x

2. Multiply -2 by 5 which equals -10

3. Your answer is -2x + -10

To solve this problem, you must apply the proccedure shown below:

1. The problem gives the following information: Harold walks 3/4 miles in each 5/6 hours. Therefore, you have to divide 3/4 miles by 5/6 hours, as below:

unit rate=(3/4)(5/6)

unit rate=(3x6)(4x5)

unit rate=18/20

3. When you simplify, you obtain:

unit rate=9/10

4. Therefore, as you can see, the answer is:**Harold's unit rate is 9/10.**

For the given **function **f(x) = | -2x + 4 |, the data is shown in the table below.

It is defined as a special type of **relationship**, and they have a predefined domain and range according to the **function **every value in the domain is related to exactly one value in the **range**.

It is given that the **function **is, f(x) = | -2x + 4

Let's begin with the table's first **line**: x = 6, When x equals 6, you are determining the value of **function **f. Evaluate the equation after substituting 6 for x.

f(6) = |-2(6) + 4|

f(6) = |-12 + 4|

f(6) = |-8|

f(6) = 8

For the Second line of the table,

x = -1

f(x) = |-2x + 4|

f(-1) = |-2(-1) + 4|

f(-1) = |2 + 4|

f(-1) = |6|

f(-1) = 6

The third **line **of the table,

f(x) = 4

f(x) = |-2x + 4|

|-2x + 4| = 4

-2x + 4 = 4 or -2x + 4 = -4

-2x = 0 or -2x = -8

x = 0 or x = 4

Line 4: f(x) = 14

f(x) = |-2x + 4|

|-2x + 4| = 14

-2x + 4 = 14 or -2x + 4 = -14

-2x = 10 or -2x = -18

x = -5 or x = 9

Thus, for the given **function **f(x) = | -2x + 4 |, the data is shown in the table below.

**Answer:**

See below.

**Step-by-step explanation:**

To complete the table, start by copying the given function.

f(x) = |-2x + 4|

Now let's start with the first line of the table: x = 6.

You are finding the value of function f when x = 6.

Replace x with 6 and evaluate the expression.

f(6) = |-2(6) + 4|

f(6) = |-12 + 4|

f(6) = |-8|

f(6) = 8

Second line of table:

x = -1

f(x) = |-2x + 4|

f(-1) = |-2(-1) + 4|

f(-1) = |2 + 4|

f(-1) = |6|

f(-1) = 6

For the third and fourth lines, you are given a y value, or the value of function f, and you are looking for x. Now you use the given value to set the function equal to, and you solve for x.

Line 3: f(x) = 4

f(x) = |-2x + 4|

|-2x + 4| = 4

-2x + 4 = 4 or -2x + 4 = -4

-2x = 0 or -2x = -8

x = 0 or x = 4

Line 4: f(x) = 14

f(x) = |-2x + 4|

|-2x + 4| = 14

-2x + 4 = 14 or -2x + 4 = -14

-2x = 10 or -2x = -18

x = -5 or x = 9

The table looks like this:

x f(x)

6 8

-1 6

0,4 4

-5, 9 14

**Answer:**

$883.40

**Step-by-step explanation:**

Calculate the amount of money needed to pay after the discount.n

$1049 × 88% = $923.12

Calculate the amount of money needed to pay after the tax.

$923.12 × 104.5% = $883.3684210526

=$883.40(rounded off to nearest cents)
