Answer: Explanation:

By composing functions, we apply one function to the result of another function. So the definition is as follows:

Therefore, what happens during the process of composing functions is that:

In other words, we send the result of through the result of

Subtract 7x+2 from 5x^2-2x

Answer:

5x^2 - 9x - 2.

Step-by-step explanation:

5x^2 - 2x - (7x + 2) The 7x + 2 must be placed in parentheses).

= 5x^2 - 2x - 7x - 2 (Distributing the negative over the parentheses).

= 5x^2 - 9x - 2.

Answer:

5x² - 9x - 2

Step-by-step explanation:

(5x² - 2x) - (7x + 2)

Distribute the (-) sign.

5x² - 2x - 7x - 2

Evaluate

5x² - 9x - 2

There are 3 red and 9 blue counters in a box. A counter is chosen and then replaced. If you did this 144 times, how many times would you expect to get a blue?

If you do it 144 times that is (3+9)*12

This means that 12 times 3 red and 9 blue counters will be chosen that means that 9 blue counters will be chosen 12 times. 9*12 is 108.

This means blue counters will be chosen 108 times.

This can be checked as 108/3 would give you the number of red counters which is 36 and 108+36 is 144

This means that 12 times 3 red and 9 blue counters will be chosen that means that 9 blue counters will be chosen 12 times. 9*12 is 108.

This means blue counters will be chosen 108 times.

This can be checked as 108/3 would give you the number of red counters which is 36 and 108+36 is 144

Alison has 1/2 cup of yogurt for making grit parfaits. Each parfait requires 1/8 cup of yogurt. How many parfaits can she make?

Alison can make 4. Because 1/2 of 8/1 = 4 if you cross out 2 and 8 so it would be 1/1 of 4/1

Trapezoid TUVW on the coordinate plane with ordered pairs at T negative 5, 5, at U negative 2, 5, at V negative 2, 2, at W negative 7, 2. If trapezoid T'U'V'W' represents trapezoid TUVW reflected over the y-axis, the ordered pair of W' is ___________. (Note: You must include parentheses, a comma, and a space after the comma when typing the ordered pair.)

Answer:

The ordered pair of W' is ( 7 , 2 ).

Step-by-step explanation:

Given: Coordinates of the vertices of Trapezoid TUVW

T( -5 , 5 ) , U( -2 , 5 ) , V( -2 , 2 ) and W( -7 , 2 )

Trapezoid TUVW reflected over the y-axis.

Reflected trapezoid name is T'U'V'W'

We need to find coordinate of W'

We know that rule for a reflection of a coordinate over the y -axis is

Using this rule we get,

Coordinate of T' = ( -(-5) , 5 ) = ( 5 , 5 )

Coordinate of U' = ( -(-2) , 5 ) = ( 2 , 5 )

Coordinate of V' = ( -(-2) , 2 ) = ( 2 , 2 )

Coordinate of W' = ( -(-7) , 2 ) = ( 7 , 2 )

Therefore, The ordered pair of W' is ( 7 , 2 )

(x,y)->(-x,y)

(-7,2)->(7,2)

(-7,2)->(7,2)

Find two consecutive whole numbers that the square root of 17 lies between.

The square root of 17 is between the integers 4 and 5

In order to know which two whole numbers the square root of 31 fall ib between, we need to get a perfect square that is less than 31 and also greater than 31

The two perfect numbers are 16 and 325

Taking the square root of these numbers;

√16 = √4 *4 = 4

√25 = √5 * 5 = 5

This shows that the square root of 17 is between the integers 5 and 6

Between which two consecutive integers does 53 lie?

52 and 54. Integers are whole numbers meaning 1..4..7..17...25 and so on. Consecutive meaning one right after the other. So 52 and 54 are the answer.
