We have the following:

They tell us that the capacity is 350, therefore that is the maximum value, it means that we must subtract the exchange rate from this value, that is, the number od tickets per hour that are sold, 23

thus

The answer is the option B.

A function relates input to output. Functions can be one to one or many to one. The x values represent the input while the y values represent the output. In the case of one to one, it means that the output has only one corresponding input. Many to one means that there are many input values for one output value. An input value cannot have more than 1 output value. If this happens, then it is not a function. Looking at the options given,

Option A is a function since no input value has more than one output value

Option B is not a function since the output values of 7 and 1 has the same input value of - 1

For option C, the values are (- 3, - 2)' (- 1, 1), (- 1, - 5), (1, 4). It is not a function since the output values of 1 and - 5 has the same input value of - 1

Option D is not a function since the output values of 7 and 1 has the same input value of - 1

The correct option is A

Given the two equations

7(x - 1) = 3y + 21

3.5x + 1.5y = 4.5

To determine if the lines are visible or perpendicular

Step 1: Expand the equations and make y the subject of the formula

7(x - 1) = 3y + 21

=> 7x - 7 = 3y + 21

=> 3y = 7x - 7 - 21

=> 3y = 7x -28

Divide both sides by 3

y = 7/3x - 28/3 ------equation 1

3.5x + 1.5y = 4.5

1.5y = -3.5x + 4.5

Divide both sides by 1.5

y = -3.5/1.5 x + 4.5/1.5

y = -7/3x + 3--------equation 2

Step 2: compare the two equations to the equation of a line, y = mx + c

For equation 1

m = 7/3

For equation 2

m= -7/3

The slopes are not the same

Also, the product of the gradients did not give -1

It can be seen that the lines are neither perpendicular nor parallel

The measure of length of GF is 16 cm.

Given that point S is the midpoint of side HG and point T is the midpoint of HF of triangle FGH, the line segment ST is parallel to the side GF, and the triangles FGH and TSH are similar with proportional sides, then:

[tex]\frac{GF}{ST}=\frac{FH}{TH}=\frac{GH}{SH}[/tex]

We are given the following;

FH = HT + FT = 6 + 6 = 12 cm [HT = FT = 6 cm]

GH = HS + GS = 4 + 4 = 8 cm [HS = GS = 4 cm]

ST = 8 cm

Substitute the given values, we will get the following;

[tex]\frac{GF}{8} =\frac {12}{6} = \frac{8}{4}\\\frac{GF}{8} =\frac {12}{6}\\\frac{GF}{8} = 2[/tex]

GF = 2 * 8 = 16 cm

Thus, the measure of the length of GF is 16 cm.

Notice that the difference between the two equations is the +5 on the right side of the second equation.

The graph of the following equations are as folllows:

For y=x:

For y=x+5:

Thus, the graph of y = x was shifted 5 units upward to obtain the graph of y=x+5.

Therefore, each value or output of y=x+5 is 5 more than the corresponding output of y=x. Consequently, the graph of y=x+5 is the graph of y=x translated up by 5 units.

Thus, the correct answer is option C.

The formula for calculating the distance between two points is given as:

Given the following coordinate points

A(2,4) and B(8,2)

Substitute the given parameters into the formula to have:

Hence the distance between the points (2,4) and (8,2) round to the nearest tenth is 6.3 units

Answer:

False

Explanation:

In the coordinate notation (x, y), the left entry represents the x-coordinate and the right entry the y-coordinate. Therefore, if we want to represent the point x = 5, y = 3, we would write

Hence, the representation (3, 5) does not represent the point x =5, y = 3, rather, it represents x = 3, y = 5, and therefore, the statement given is false.
