Answer:

The total cost of the games (play package)

= 15x - 5

Step-by-step explanation:

Number of tokens in the games = 15

The cost per token = x

Discount off the total cost = $5

Therefore, the cost of the play package = 15x - 5

where x is in dollars

However, ‘x’ can also assume any value.

Check:

If x = $15

The total cost of the game can be said to be 15(10) - 5 = $220

Answer:

T= 160 + 4x

Step-by-step explanation:

Giving the following information:

The $160 fine is a fixed cost. It will remain constant.

The $4 additional fine acts as a variable cost. It varies with the number of miles per hour.

To calculate the total cost (T), we need to use the following formula:

T= 160 + 4x

x= miles per hour exceeding the speed limit.

Answer:

X=13

Step-by-step explanation:

So if ΔABC ≅ ΔDEC, then that means that ∠B is ≅ ∠E. Therefore you would write the equation 3x=6x-39 and solve for X to get 13.

Explanation:

To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.

First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.

Let's identify some like terms below.

f(x)=−4x+3x2−7+9x−12x2−5x4

Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:

f(x)=5x+3x2−7−12x2−5x4

Let's do the same thing with the x-squared terms:

f(x)=5x+3x2−7−12x2−5x4

f(x)=5x−9x2−7−5x4

Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:

f(x)=−5x4−9x2+5x−7

Step-by-step explanation:

Another word for finding the opposite of an integer is negative number of an integer.

Decrease, spend, and decline are examples of words that mean negative. An integer is any positive whole number or its opposite. Here, opposite means sign. So a positive integer has a negative opposite and vice versa.

Answer:

9 9/25

Step-by-step explanation:

Answer:

the answer is 9 9/25

Step-by-step explanation:

The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

The cosine ratio is given as:

[tex]\cos(x) = -\frac 14[/tex]

Calculate sine(x) using the following identity equation

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So we have:

[tex]\sin^2(x) + (1/4)^2 = 1[/tex]

[tex]\sin^2(x) + 1/16= 1[/tex]

Subtract 1/16 from both sides

[tex]\sin^2(x) = 15/16[/tex]

Take the square root of both sides

[tex]\sin(x) = \pm \sqrt{15/16[/tex]

Given that

tan(x) < 0

It means that:

sin(x) < 0

So, we have:

[tex]\sin(x) = -\sqrt{15/16[/tex]

Simplify

[tex]\sin(x) = \sqrt{15}/4[/tex]

sin(2x) is then calculated as:

[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]

So, we have:

[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]

This gives

[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

The question implies the two angles are equal because of the positioning of the named vertices. m∠A = m∠E so to say.

You can substitute the values and solve the inequality to find x, then solve for m∠A.

m∠A = m∠E; Given (Inferred)

6x - 8 = 4x + 1; Substitution

6x = 4x + 9; Addition Property of Equality

2x = 9; Subtraction Property of Equality

The graph of equation y = - 2x - 1 and the y-intercept (0, - 1) is shown in image.

We have to given that,

To plot the equation y = - 2x - 1 and the y-intercept on the graph.

Since, The equation of line in slope intercept form is,

y = mx + c

Where, m is slope and c in y - intercept.

Here, Equation is,

y = - 2x - 1

After comparing,

y - intercept = - 1

So, y - intercept of equation (0, - 1)
