Complete the following statements using m(x) = x² and n(x) = x – 3.

m(n(x)) = m(x – 3)
= (
x – 3
)²


n(m(x)) = n(x²)
= x² –



Because m(n(x)) is
n(m(x)), the composition of m and n is not commutative.

Therefore, function composition is not commutative.

Aaliyah needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 3 hours and charged her $66 for parts. The total was $441. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.

Equation:
Answer: x =

Answers

Answer:

x=125

Step-by-step explanation:

First identify what the varible means,

x = the cost of the labor per hour.

Next, write out an equation

3x + 66 = 441

Solve,

3x+66=441

Step 1: Subtract 66 from both sides.

3x+66−66=441−66

3x=375

Step 2: Divide both sides by 3.

3x/3 = 375/3

x=125

I don’t understand this

Answers

Answer:

so, for each of the questions you have to change the expression into slope intercept form, then use that equation to graph a line on the graph.

i'll help you out:

11. y= 3/2x+5 (0,5) (-4,2 )

12.y= -2x-5 (0,-5) (-1,-3)

13. y= -2x-3 (0,-3) (-1,-1)

14. y= x-4 (0,-4) (4,0)

Step-by-step explanation:

the first expression is the slope intercept form and the parenthesis are the points.

Answers

Answer:

10 apples

Step-by-step explanation:

We can write a ratio to solve

3 oranges     15 oranges

--------------- = -----------------

2 apples           x apples

Using cross products

3x = 2 * 15

3x = 30

Divide by 3 on each side

3x/3 = 30/3

x = 10

area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh

Answers

Answer:

8m

Step-by-step explanation:

We can convert the trapezium into a rectangle to make finding the area easier.

Say that the top side is 9m, and that the bottom side is 12m.

12 - 9 = 3

3/2* = 1.5

*Note that we are dividing by two to get the "overhang" of the bottom side.

Now that we have our overhang, we can find the length of the "t-rect"**.

**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.

12 - 1.5 = 10.5

9 + 1.5 = 10.5

The length of the t-rect is 10.5.

84/10.5 = 8

The height of the t-rect is 8m.

Since the height of the original trapezium is equal to the height of the t-rect***,

***Since we have only adjusted the length

this also means that 8m would also be the height of the original trapezium.

Now, there is a second way of doing this.

Find the median of 12 and 9.

9, 10, 11, 12

10, 11

The median is 10.5.

84/10.5 = 8

You get the same answer. These methods could be used as a solve-then-check method to another problem like these.

Hope this helps. Have a nice day.
