Answer:

Step-by-step explanation:

We can solve this in either of two ways.  I'll do both.

Mathematically

3x + 2y = 8

5x + 2y = 12

Rewrite either equation to isolate y.  I'll use

3x + 2y = 8

2y = 8 - 3x

y = (8-3x)/2

Now use this value of y in the other equation:

5x + 2y = 12

5x + 2((8-3x)/2) = 12

5x + (8 - 3x) = 12

2x = 4

x = 2

Use x=2 to find y:

y = (8-3x)/2

y = (8-3*(2))/2

y = (8-6)/2

y = 1

The point is (2,1)

Graphically

Graph the two equations and find the point they intersect.  See attachment.

The quotient of the equation is [tex]\rm x^2+4x+3[/tex].

Divided the equation [tex]\rm (x^3-x^2-17x-15)[/tex] by [tex]\rm (x-5).[/tex]

The synthetic method involves finding zeroes of the polynomials.

The quotient of the equation is;

[tex]\rm= \dfrac{x^3-x^2-17x-15}{x-5}\\\\= \dfrac{(x-5) (x^2+4x+3)}{x-5}\\\\= x^2+4x+3[/tex]

Option (C) a sequence of statements that demonstrates the truth of an assertion is the best definition of mathematical proof.

A mathematical proof is an inferential justification for a mathematical claim that demonstrates how the premises logically support the conclusion.

As we know, mathematical proofs are a set of sequential statements that assist in demonstrating the truth of a proposition.

For example:

2n + 1 = 3n

If n = 1 the above expression is true.

To proof the above expression plug n = 1:

2(1) + 1 = 3(1)

2 + 1 = 3

3 = 3  (true)

Thus, option (C) a sequence of statements that demonstrates the truth of an assertion is the best definition of mathematical proof.

The y-intercept represents the initial temperature of the liquid before cooling  and the slope represent the changes in temperature for every m minutes.

y = 100 - 5m

where

y = temperature in degree Celsius

m = cooling for number of minutes

Using the slope intercept equation,

where

m = slope

b = y-intercept

Therefore,

y - intercept = 100

slope(m) = 5

Therefore, the y-intercept represents the initial temperature of the liquid before cooling  and the slope represent the changes in temperature for every m minutes.

We should confirm that f(x) has an inverse in the first place. If it does, then

[tex]f\left(f^{-1}(x)\right) = x[/tex]

Given that f(x) = x/(2 - x), we have

[tex]f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)}{2 - f^{-1}(x)} = x[/tex]

Solve for the inverse:

[tex]\dfrac{f^{-1}(x)}{2 - f^{-1}(x)} = x[/tex]

[tex]f^{-1}(x) = 2x - x f^{-1}(x)[/tex]

[tex]f^{-1}(x) + x f^{-1}(x) = 2x[/tex]

[tex]f^{-1}(x) (1 + x) = 2x[/tex]

[tex]f^{-1}(x) = \dfrac{2x}{1+x}[/tex]

Then

[tex]f^{-1}(-2) = \dfrac{2(-2)}{1-2} = \boxed{4}[/tex]

Note that this is the same as solve for x when f(x) = -2 :

x/(2 - x) = -2   ⇒   x = 4

Answer:

Child's ticket is $14.   [14, without the symbol]

Senior ticket is $8.     [8, without the symbol]

(WHAT???)

Step-by-step explanation:

Let S and C stand for the numbers of Senior and Child tickets sold.

We can write equations for both days:

Day 1:   3S + 1C = 38  [sold 3 senior citizen tickets and 1 child ticket for a total of $38]

Day 2:  3S + 2C = 52  [$52 on the second day by selling 3 senior citizen tickets and 2 child tickets]

Since both equations has a "3S" term, we can easily subtract one from the other:

3S + 1C = 38

-3S - 2C = -52

        - C = -14

C = 14  The price of a children's ticket is $14.

Use C = 14 in either equation to find S:

3S + 1C = 38

3S + 14 = 38

3S          = 24

S = 8  The price of a senior ticket is $8.
