Najat is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.

Using x for the number of tickets and y for the cost, do the following.

Write an equation relating x and y

Answer:

x = -3

Step-by-step explanation:

First solve it:

Subtract the x's from both sides

2y = -3x +8

2y = -5x +2

Divide by two

y= -1.5x + 4

y = -2.5x +1

set them equal to each other:

-1.5x +4 = -2.5x +1

Add 2.5 x to both sides

1x +4 = 1

x +4 = 1

subtract 4 from both sides

x = -3

Answer:

true

Step-by-step explanation:

Answer:

[tex]S(x) = x + \frac{1}{x}[/tex] --- Objective function

Interval = [tex]\{x:x=1\}[/tex]

Step-by-step explanation:

Given

Represent the number with x

The required sum can be represented as:

[tex]x + \frac{1}{x}[/tex]

Hence, the objective function is:

[tex]S(x) = x + \frac{1}{x}[/tex]

To get the the interval, we start by differentiating w.r.t x

Using first principle, this gives:

[tex]S'(x) = 1 - \frac{1}{x^2}[/tex]

Equate S'(x) to 0 in order to solve for x

[tex]0 = 1 - \frac{1}{x^2}[/tex]

Subtract 1 from both sides

[tex]0 -1 = 1 -1 - \frac{1}{x^2}[/tex]

[tex]-1 = - \frac{1}{x^2}[/tex]

Multiply both sides by -1

[tex]1 = \frac{1}{x^2}[/tex]

Cross Multiply

[tex]x^2 * 1 = 1[/tex]

[tex]x^2 = 1[/tex]

Take positive square root of both sides because x is positive

[tex]\sqrt{x^2} = \sqrt{1[/tex]

[tex]x = 1[/tex]

Representing x using interval notation, we have

Interval = [tex]\{x:x=1\}[/tex]

To get the smallest sum, we substitute 1 for x in [tex]S(x) = x + \frac{1}{x}[/tex]

[tex]S(1) = 1 + \frac{1}{1}[/tex]

[tex]S(1) = 1 + 1[/tex]

[tex]S(1) = 2[/tex]

Hence, the smallest sum is 2

Answer:

Percent Change is 16%

The change is increased.

Step-by-step explanation:

The original amount = 25

Amount increase = 4

We need to find percent increase

The formula used is: [tex]\frac{Amount \ increased}{Original \ Amount}*100[/tex]

Putting values in formula

[tex]Percent \ Change = \frac{Amount \ increased}{Original \ Amount}*100\\Percent \ Change =\frac{4}{25}*100\\Percent \ Change =16 \%[/tex]

So, Percent Change is 16%

The change is increased.

Answer: x = 15

we have: (6x - 5)° + (6x + 5)° = 180°

⇔ 12x = 180

⇔ x = 180/12=15

Answer:

32

Step-by-step explanation:

5:4 is the ratio. So 40/5 is 8. Therefore, you must multiply 4 by 8 to get the amount of females at the camp. Ergo, the answer is 32

Answer:

32

Step-by-step explanation:

You can solve this by setting up a proportion.

A 5 to 4 ratio is the same as [tex]\frac{5}{4}[/tex]

The proportion is [tex]\frac{5}{4}[/tex] = [tex]\frac{40}{x}[/tex]

By cross multiplying... you find that x (females) is equal to 32

Answer:

To factor a polynomial, identify the greatest common factor of the monomial terms, and then use the Distributive Property to rewrite the expression. Once a polynomial in a • b + a • c form has been rewritten as a(b + c), where a is the GCF, we say that the polynomial is in factored form.

Answer:

The slope of line is 0 given points (2,8)(7,8)

Step-by-step explanation:

We need to find slope of line given points (2,8),(7,8)

The formula used to find slope of line is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given:

[tex]x_1=2, y_1=8, x_2=7 \ and \ y_2=8[/tex]

Finding slope using formula:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0[/tex]

So, the slope of line is 0
