Answer:

y=mx+b, where x and y are variables, m is the slope, and b is the y-int

Since there is no m value, it is 1/1 or simply 1. Therefore you rise 1 point for every 1 you move right.

Your graph needs to intercept the y-axis at point (0,6).

The easiest way to graph this equation is to plot a point at (0,6) and then start your slope of 1/1.

23000 $20 tickets

Ax +By = C is the typical form for two-variable linear equations. For instance, the equation 2x+3y=5 is a standard form linear equation .Finding both intercepts is rather easy when an equation is supplied in this style (x and y).

$8 tickets for x.

$15 tickets are y.

$20 tickets = z

8x + 15y + 20z = 783000 when y = 2x z = y + 6000.

The formula for finding the slope is;

m = Δy/Δx

Where, m is the slope

The given equation of line is;

x = 3 comparing it with standard form of equation;

y = mx + c

As, the equation is a straight line passing parallel to x axis, the slop of line x = 3 is ∞.

Thus, m₁ =  ∞.

Now, let the slops of the line passing from (-2, 5) is m₂,

The current price index is mathematically given as,$538.194

By increasing the ratio of the current value to the reference value by 100, one can determine the index value.

Given that the current cost of gasoline is $3.10 per gallon. we need to find the current price index number, using the 1975 price of 56.7 cents as the reference value.

In regard to this issue, we have that:

Current value = $3.10

Reference value: $0.576

Typically, the mathematical formula for the Index price is,

See explanation below

Explanation:

From the question, we are told line TV is perpendicular to line US.

This means the point which they intersect has an angle of 90°.

We are also told line TV bisects STU.

For a line to bisect an angle, it means it divided the angle into two equal parts.

When line TV bisects STU, it divided it into angle STR and angle UTR

Hence, ∠STR = ∠UTR

Also line SU and line and line VT intersect to give vertical angles.

Angle R and the angle opposite it are vertical angles.

Vertical angles are equal.

The angle with 90° and the angle opposite it is also a vertical angle.

you can see from the illustration. The two angles opposite each other are equal to 90°.

Since angle on a straight line = 180°

angle R + 90° = 180°

angle R = 180-90

angle R = 90°

All the 4 angles that result from the intersection line VT and line SU are equal to 90°

Based on the interval, the average rate of change of the function is 4.0

The graph that completes the question is added as an attachment

From the graph, we can see  that the equation of the graph is a quadratic equation

Also, from the question:

We have the interval to be:

The interval is given as

x = -4 to x = 2

This can be represented as

(a, b) = (-4, 2)

From the attached graph, we have

f(-4) = 22

f(2) = -2

The estimate of the average rate of change f is calculated as(to one decimal place)

Rate = [f(b) - f(a)]/[b - a]

Substitute the known values in the above equation

This gives

Rate = [f(2) - f(-4)]/[2 + 4]

Substitute the known values in the above equation

So, we have

Rate = [-2 - 22]/[2 + 4]

Evaluate

Rate = -4.0

Hence, the estimate (to one decimal place) of the average rate of change of the graph is 4.0

The measure of the angle is 1.0 when rounded to one decimal places.

If one of the triangle's angles is 90 degrees, the triangle is said to have right angles. The triangle with a right angle is known as a right triangle because a right angle is 90 degrees. Using the Pythagorean rule, it is simple to understand how the different sides of this triangle relate to one another. The greatest side of a right angle is known as the hypotenuse, and it is opposite the right angle. In addition, the right triangles are categorized as isosceles right triangles and scalene right triangles based on the other angle values. Pythagorean triples are another name for the right triangle's side lengths, which include 3, 4, and 5.

Given that : right triangle, we're provided the hypotenuse and the leg next to. We can use the cosine ratio to determine :

Cosθ =[tex]\frac{adjacent}{hypotenuse}[/tex]

Plug in the given information

Cosθ =[tex]\frac{4}{7}[/tex]

Use the inverse cosine ratio

θ = [tex]cos^{-1} \frac{4}{7}[/tex]

The probability that a ball is not red is 3/5 and the probability that the ball is red or white is 2/3 .

Mathematical descriptions of the likelihood that an event will happen or that a proposition is true are dealt with in the discipline of mathematics known as probability.

In the given question there are  6 red balls, 4 white balls, and 5 blue

balls.

Total number of balls = 6+4+5 = 15 balls (sample space)

Red balls = 6

Not red balls = 15 - 6 = 9

Probability that the ball is red = 9/15 = 3 /5

Red and white balls = 6 + 4 =10

Probability that the ball is red or white = 10 / 15 = 2 / 3
