Answers

Answer 1
Answer:

Answer:

percent decrease

Step-by-step explanation:

I believe it is 75% sorry if I'm wrong
Answer 2
Answer:

Answer:

83%

Step-by-step explanation:

original amount:3

final amount: 0.5

percent change= amount of change/original amount

amount of change = greater value-lesser value =3-0.5=2.5

percent change=2.5/3=0.83=83%

Alex and Jackson are brothers who are selling mums for a football fundraiser. Together they have sold 37 mums. If Alex has sold 19 more mums than Jackson, how many mums has Jackson sold? Use X to represent the number of mums alex sold and y to represent the number of mums Jackson sold.

Answers

Jackson has sold 18, that’s the only possibility.

x = mums sold by Alex

y = mums sold by Jackson

\boxed{\begin{array}{llll} \stackrel{ \textit{together they've sold 37} }{x + y = 37} \n\n\n \stackrel{ \textit{Alex has sold}}{x} = \stackrel{ Jackson }{y} + 19 \end{array}}\hspace{5em} \begin{array}{llll} \stackrel{\textit{substituting on the 1st equation}}{(y+19)~~ + ~~y~~ = ~~37}\n\n 2y+19=37\n\n 2y=18\n\n y=\cfrac{18}{2}\n\n y=9 \end{array}

If f(–5) = 0, what are all the factors of the function f(x) = x^3 - 19x + 30. Use the Remainder TheoremA (x – 2)(x + 5)(x – 3)
B (x + 2)(x – 5)(x + 3)
C (x – 2)(x + 5)
D (x + 2)(x – 5

Answers

If f(-5)=0, then x+5 is first factor of given polynomial.

1. Divide polynomial x^3 - 19x + 30 by x+5:

x^3 - 19x + 30=(x+5)(x^2-5x+6).

2. Factor the trinomial x^2-5x+6:

.

3. Then

x^3 - 19x + 30=(x+5)(x-2)(x-3).

Answer: correct choice is A.

The factors of the function f(x) = x³ - 19x + 30 are (x + 5)(x - 2)(x - 3).

Option A is the correct answer.

We have,

To determine the factors of the function f(x) = x³ - 19x + 30 using the RemainderTheorem, we need to find the values of x that make the function equal to zero.

Given that f(-5) = 0, we know that (x + 5) is a factor of the function.

Using syntheticdivision, we can divide f(x) by (x + 5):

     -5 |   1    0   -19   30

         |       -5    25  -30

      -----------------------

          1   -5     6    0

The result is a remainder of zero, indicating that (x + 5) is a factor.

Now we need to factorize the remaining quadratic expression:

1x² - 5x + 6.

This quadraticexpression factors as (x - 2)(x - 3).

Therefore,

The factors of the function f(x) = x³ - 19x + 30 are (x + 5)(x - 2)(x - 3).

Christiana works at Texas Road House and makes $50 each night in tips plus $7.50 per hour. Write a function rule in function notation where M is the total money she makes and h is the number of hours she works in one night.

Answers

Answer: M = 50 + 7.50 h

Step-by-step explanation:

As per the given scenario,

Total money Christina made = (Money she made in tips) + (Per hour wage ) x (Number of hours she work in one night)   (i)

Let M is the total money she makes and h is the number of hours she works in one night.

Here, Money she made in tips = $ 50

Per hour wage = $7.50

So substitute all the values in (i), we get

M = 50 + 7.50 h

Hence, the required function is M = 50 + 7.50 h.
