y = -2x + 5a. What is the slope? b. What is the vertical intercept? c. What is the horizontal intercept? d. Graph the equation

We are given a problem that can be solved using a system of linear equations. Let A, be the number of adults, and S the number of students. Since there are in total 142 people and there were two days, this means that the sum of the number of adults and the number of students must be 284, which can be written mathematically as follows:

This is our first equation. The second equation is found using the total sales of $1948. Since the ticket per adult is $8 and per student is $5, we have the following equations:

To solve this equation we will solve for A in equation (1), by subtracting S to both sides;

Now we will replace this value in equation (2):

Now we will apply the distributive property:

Addins like terms:

Subtracting 2272 to both sides;

Dividing both sides by -3:

Now we replace this value in equation (1), where we have already solved for A:

Therefore, there were sold 108 student tickets and 140 adult tickets.

Answer:

[tex]\frac{1}{12}[/tex]

Solution

The range is as given below

Hence, the range is

{-8, -5, -2, 1}

Let us form a table showing the domain(x) and the range (g(x))

Let us use the table to plot graph of the domain(x) against the range(g(x)) as below

1) Since the sum of these angles is written in terms of x, we can write it out:

Notice that to sum these fractions we had to take the LCM(2, 1) = 2 and rewrite it as a sum.

2) Another way of writing the sum of these angles is writing it as a sum of decimal numbers since we can rewrite fractions as decimal numbers.

Answer:

10

Step-by-step explanation:

I divided 570 by 15 to see how many miles she can travel per gallon of gas which came out to be 38.

After that i divided the 380 by the 38. 380÷38 is 10.

Answer:

Need:

10 gallons

Step-by-step explanation:

Proportions:

15 gallons ⇒ 570 miles

A gallons ⇒ 380 miles

A = 15gallons * 380miles / 570miles

A = 10 gallons

Explanation

We are asked to find the total annual budget given that the combined amount for sales and editorial is $12,500,000

To do so, let the total combined amount be x

If we check for the combined percentages for the amount for sales and editorial, we will have

Thus, we can set up the equation

Solving for x

Therefore, the total annual budget will be $50,000,000

w= -7

Explanation

Step 1

The addition property of equality and subtraction property of equality are similar. Adding or subtracting the same number to or from both sides of an equation keeps both sides equal, so we can use this fact to isolate w

a) subtract 6 in both sides of the equation

Step 2

The division property of equality states that when we divide both sides of an equation by the same number, the two sides remain equal.so

b) divide both sides by 4

therefore, the answer is

w= -7

In order to find the equation that passes through both points, we can use the slope-intercept form of the linear equation:

Where m is the slope and b is the y-intercept.

Using the given points on this equation, we have:

Therefore the equation is y = -x + 4 (correct option: C)

The z-score is given by the following formula:

Where x is the data point, μ is the mean, and σ is the standard deviation.

First

The general form of a quadratic equation is expressed as

ax^2 + bx + c = 0

In order to write the equation, we would substitute values for a, b and c. If a = 3, b = 8, c = 25, the equation would be

If we graph this parabola we can see the vertex at point (4, 16)

The axis of simmetry is a vertical line that passes through the vertex of the parabola.

Any vertical line's equation is:

'a' is any value of x.

Answer:

The equation of the axis of simmetry is x = 4

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

2x - 8 < 7

Step 02:

inequality:

2x - 8 < 7

2x - 8 + 8 < 7 + 8

2x / 2 < 15 / 2

x < 15 / 2

The answer is:

x < 15 / 2

(-oo , 15/2)

The fraction that represent the point A is -1/4.

Since there are 4 divition in between -1 and 0.

Thus the length of one division is,

Answer: Third option:

For the given functions, the two compositions are:

(f o g)(x) =  9x² + 5

(g o f)(x) = 3*x² + 15

Here we have two functions which are:

f(x) = x² + 5

g(x) = 3x

Now we want to find the compositions:

(f o g)(x) = f( g(x) )

So we just need to evaluate f(x) in g(x), we will get:

f( g(x) ) = g(x)² + 5

f( g(x) ) = (3x)² + 5 = 9x² + 5

The other composition is:

(g o f)(x) = g(f(x))

And we can get this in a similar way:

g(f(x)) = 3*f(x)  = 3*(x² + 5) = 3*x² + 15

The domain of a function is always represented by the values of X. In the ordered pair, they are always the first value of the pair.

The domain is the first number of each pair.

Domain: {-1, -10, 8, 6}.

- 5x + 4 > 19

1st step let us move 4 to the other side by subtracting both sides by 4

- 5x + 4 - 4 > 19 - 4

- 5x > 15

2nd step is move - 5 to the other side by dividing both sides by -5, BUT when we divide the sides of an inequality by a negative number we must reverse the sign of inequality
