Given that:

x = number of adult tickets.

y = number of children's tickets.

And the ordered par (4, 3).

Since an ordered pair is represented by (x, y):

x = 4 = number of adult tickets.

y = 3 = number of children's tickets.

Answer: A. Ms. Monti bought 4 adults tickets and 3 children's tickets.

First, let's put the numbers that are not in the decimal form in this form:

Graph this line using slope ​

Slope = (y2-y1)/ (x2-x1)

y = m x +b

the slope is m

The y-intercept is (0, b)

_____________________

y = 2x +4 (yellow line)

The slope = 2 = 2/1 = (y2-y1)/ (x2-x1)

The y-intercept is (0, 4)

x= 0

y = 4

First draw the point (0, 4)

x= 0

y = 4

- Since the slope is 2 = variation in y / variation in x

From (0,4) the next point could be 1 more in x and 2 more in y (1, 6)

To continue

From (1,6) the next point could be 1 more in x and 2 more in y (2, 8)

From (2,8) the next point could be 1 more in x and 2 more in y (3, 10)

From (3,10) the next point could be 1 more in x and 2 more in y (4, 12)

___________________________________________

You only have the positive part so you won't need this

From (0,4) the next point could be 1 less in x and 2 less in y (-1, 2)

To continue

From (-1, 2) the next point could be 1 less in x and 2 less in y (-2, 0)

Answer:

6 apps

Step-by-step explanation:

The trick to this question is that you must stay under $25 dollars. Make a rough estimate to the answer. Suppose each a[[ costs 4 dollars.

Then the total number you can but is 25/4 = 6.25 spps. But you can't buy 1/4 of an app, so the answer must be 6.

To be just a bit formal

1 app costs 3.99 dollars

6 apps cost 3.99 * 6 = 23.94 dollars.

What happens if you try and buy the 7th app?

7 apps cost 3.99 * 7 = 27.93 which is over 25.

You cannot by 7 apps.

You can only buy 6 apps.

Therefore, the correct answer is the 2nd option: 3 w - 4 = 5

The empirical probability of flipping heads on the coin AND rolling a four on the die is 0.623.

What is probability?

When we do not really know how something will turn forth, we can talk about the probability of one outcome or the likelihood of several.

Given that,

the coin is flipped = 2,500 times.

heads =1,223 times and tails= 1,277 times.

and

A die was rolled = 60 times

one—11 times, two—9 times, four—12 times, five—12 times, and six—8 times.

The empirical probability of flipping heads on the coin AND rolling a four on the die = (1223/2500) + (8/60)

=0.623

The empirical probability of flipping heads on the coin AND rolling a four on the die is 0.623.

Note that:

The first quadrant of a graph belongs to the negative x - axis, and the positive y-axis

Since it is stated that the points of the preimage belong to the first quadrant, we can reasonably selects the values of Points A, B, C, and D that obey this instruction.

1) Coordinates of the preimage in the first quadrant

Let us selects arbitrary coordinates that belong to the first guadrant for the points:

A(-1, 2), that is, x = -1, y = 2

B(-1, 6), that is, x = -1, y = 6

C(-3, 2), that is, x = -3, y = 2

D(-3, 6), that is, x = -3, y = 6

2) Coordinates of the image after translating the object by 7 units left (i.e x -7) and 3 units up (i.e y + 3)

The preimage is translated 7 units left and 3 units up. The coordinates of the points become:

A' (-1-7, 2+3)

A' (-8, 5)

B' (-1-7, 6 + 3)

B'(-8, 9)

C'(-3-7, 2+3)

(13) The angles are alternate interior angles .

(15)  The angles are vertically opposite angles.

In a plane, parallel lines are any lines that do not meet or intersect at any point. They are always parallel and equally spaced apart from one another. Lines that are parallel do not intersect. Infinity is where parallel lines meet, as well.

Additionally, pairs of angles, such as the ones below, are created when a transversal intersects two parallel lines.

Two lines are said to be intersecting if they cross at a single point in a plane. Perpendicular lines are those that cross one other at a 90-degree angle. In a plane, two lines are said to be parallel if they never cross at any point.

g(x) = x - 3

h(x) = 3x + 1

To find g(h(x)), you have to replace x = h(x) into g(x), as follows:

g(h(x)) = (3x + 1) - 3

g(h(x)) = 3x + (1 - 3)

g(h(x)) = 3x - 2

To find h(h(x)), you have to replace x = h(x) into h(x), as follows:

h(h(x)) = 3(3x + 1) + 1

h(h(x)) = 3(3x) + 3(1) + 1

h(h(x)) = 9x + 3 + 1

h(h(x)) = 9x + 4

Given data:

The given nnumber is 8/3.

The given number is lie between 2 and 3 , more close to 3.

Here, each division is one unit and the dot represent the number which is lies bewteen 2 and 3.

When we have two numerical sets of data, it's either we have a positive association, negative asscociation or no association.

When we have a negative association, one variable increases as the other variable decreases.

Take a scatter plot as an example. In a scatter plot, if the x variable is increasing as the y variable decreases, we can say that both variables have a negative association.

While if the x variable is increasing as the y variable is increasing, both variables have a positive association.

Therefore, when two numerical sets of data have negative association, the correct statement is:

As one variable increases, the other variable decreases.

D. As one variable increases, the other variable decreases

The interest that would be paid on the loan is $1,505.35.

Interest is the amount that a debtor has to pay the creditor for use of her funds. The interest that is paid on a loan depends on the interest rate, duration of the loan and the amount borrowed.

Th amount of interest can be determined using the simple interest formula.

Interest = loan amount x interest rate x duration of the loan

Interest = $35,500 x 10.25% x (151 / 365)

Interest = $35,500 x 0.1025 x 0.41370
