Answer:

  f(x) = 19.8x +1080.2

Step-by-step explanation:

The given values form an arithmetic sequence with first term (a1) = 1100 and common difference (d) = (1119.80-1100) = 19.80.

The generic term of an arithmetic sequence is ...

  an = a1 +d(n -1)

  an = 1100 +19.8(n -1) = 1080.2 +19.8n

Expressed as a function of x, this is ...

  f(x) = 19.8x +1080.2

Answer:

[tex]1/3[/tex]

Step-by-step explanation:

There are 6 values on a die, and we want 2 values. The fraction now is [tex]2/6[/tex]. But, wait! We can simplify this fraction: [tex]1/3[/tex].

Side note:

I understand if you wanted just the [tex]2/6[/tex] fraction and not simplified.

Answer:

Step-by-step explanation:

It seems like there is only one question. I'll answer that first and then we'll discuss what might be inferred from the introduction.

1)

The way the problem is set up you get a factoring to take place

(x^3 - 8) = (x - 2)(x^2 + 2x + 4)

                 ================      

                   (x - 2)

This question is unique. They expect you to cancel, which leaves you with y = x^2 + 2x + 4) which is a quadratic.

The reason you don't put in x = 2 is because technically, you get 0/0 which can be shown to be either 1 or 0. To get out of that, we say that 0/0 is undefined. The graphing program has taken the stance that 0/0 is 1. However I wouldn't really accept that. The whole problem comes down to 0/0 which is undefined.

Answer:

13x – 7

Step-by-step explanation:

If "a number represents x", then:

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x →

(4x + 9x) + -7 →

(13x) + -7 →

(13x) – 7 →

13x – 7.

The unknown number will be equal to 4.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the sum of 4 times a number and - 7, added to 9 times the number is 45. The value of the unknown number will be calculated as below:-

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x = 45

(4x + 9x) + -7 = 45

(13x) + -7 = 45

(13x) – 7 = 45

13x – 7 = 45

13x = 45 + 7

13x = 52

x = 4

Therefore, the unknown number will be equal to 4.

The complete question is given below:-

The sum of 4 times a number and - 7, added to 9 times the number is 45. Calculate the value of an unknown number.

Let the first even number be 'x' & the second even number be (x + 2)

According to the Question,

⇒x + (x + 2) = 34

⇒x + x + 2 = 34

⇒2x + 2 = 34

⇒2x = 34 - 2

⇒2x = 32

⇒x = 32/2

⇒x = 16

⇒First even number = x = 16

⇒Second even number = (x + 2) = 16 + 2 = 18

∴ The two consecutive even numbers are 16 & 18 ...!

As, In our Question it was given that "The sum of two consecutive even numbers is thirty-four". So, as we got our two consecutive even numbers as 16 & 18 ... By this, we can say that these both even numbers should be equals to 34, i.e., 16 + 18 = 34. Hence, The equation which we formed is correct ...!

The equation:

[tex]x + ( x+ 2) = 34[/tex]

The solution:

[tex]x + x + 2 = 34[/tex]

[tex]2x + 2 = 34[/tex]

[tex]2x = 34 - 2[/tex]

[tex]2x = 32[/tex]

[tex]x = \frac{32}{2} [/tex]

[tex]x = 16[/tex]

The numbers would be 16 and 18.

Hello!

We know that mike can bind 109 flowers per hour.

Lets create an equation to remember this.

Mikes equation:

109x = y

<x is representing per hour in this math problem>

We know that John can bind 116 flowers per hour, here is his equation.

Johns equation:

116x = y

Question: If they work together for 5 hours, how many flowers  can they bind?

First, plug in the number five in both equations.

Second, solve the equation by multiplying.

Mikes:

109(5) = y

109 times 5 is 545

y = 545

Johns:

116(5) = y

116 times 5 is 580

y = 580

We want to know how many flowers can they bind if they work together.

This means we need to add the answers of the equations from both mike's and john's together.

545 + 580 = 1,125

The answer is 1,125

Answer:

  20 pounds

Step-by-step explanation:

Often, mixture problems are worked by writing two equations: one for the total quantity of constituents in the mix, and one for the total price of the mix. When these equations are solved by substitution, the first step is to write one quantity in terms of the other.

You can save an equation and a step by using one variable for quantity. It usually works best to let the variable represent the highest-cost (or most concentrated) contributor. Here, that is the quantity the problem asks for, so ...

Let c represent the number of pounds of cashews needed to be mixed with the peanuts. Then the revenue from selling the mix is ...

  80($1.50) +c($4.00) = (80+c)($2.00)

  120 +4c = 160 +2c . . . . . divide by $, simplify

  2c = 40 . . . . . . . . . . . . . subtract 120+2c from both sides

  c = 20 . . . . . . . . . . . . . divide by 2

The manager should mix 20 pounds of cashews with the 80 pounds of peanuts.

Answer: The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.

Step-by-step explanation:

Let the Hayes family sprinkler used = 50 - x hr.

Butler family sprinkler used = x hr.

20 (50 - x) + 15x = 825

1000 - 20x + 15x = 825

175 = 5x

5x = 175

x = 35

The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.

Hello there!

We are given the function:

[tex] \displaystyle \large{ f(x) = | - 2x| - 3} \\ [/tex]

To find the range, we know that domain is the set of all x-values and also called 'input' while range is the set of all y-values and also called 'output'.

Basic Function - you add the input, you get the output. You add x-value in a function, you get y-value. You add domain, you get range.

So, we substitute x = 1,2 and 3 in the function.

x = 1

[tex] \displaystyle \large{ f(1) = | - 2(1)| - 3} \\ \displaystyle \large{ f(1) = | - 2| - 3} \\ [/tex]

Recall that any numbers in absolute value are always positive.

[tex] \displaystyle \large{ f(1) = 2 - 3} \\ \displaystyle \large{ f(1) = - 1} \\ [/tex]

x = 2

[tex] \displaystyle \large{ f(2) = | - 2(2)| - 3} \\ \displaystyle \large{ f(2) = | - 4 | - 3} \\ \displaystyle \large{ f(2) = 4 - 3} \\ \displaystyle \large{ f(2) = 1}[/tex]

x = 3

[tex] \displaystyle \large{ f(3) = | - 2(3)| - 3} \\ \displaystyle \large{ f(3) = | - 6| - 3} \\ \displaystyle \large{ f(3) = 6 - 3} \\ \displaystyle \large{ f(3) = 3}[/tex]

Therefore, Range: {-1,1,3}

Let me know if you have any questions!

It appears Jake said 5-2 = 3 for the denominator portions. This is not correct. In order to subtract fractions, the denominators must be the same and they stay the same the entire time. Only the numerators (aka stuff up top) are being subtracted.

Currently 3/5 - 1/2 cannot be subtracted since the 5 and 2 are different denominators. But we can say this:

3/5 = 6/10

1/2 = 5/10

and then from there, we can say:

3/5 - 1/2 = 6/10 - 5/10 = (6-5)/10 = 1/10

So in short,

3/5 - 1/2 = 1/10
