The distance Rhea travelled is the perimeter around the triangle.

The first step in finding the perimeter is finding the side lengths and for that, the following distance formula is used.

where (x_1, y_1) and (x_2, y_2) are the coordinates of the two points.

The distance between L(-1,6) and M(-4,2) is

Similarly, the distance between L(-1,6) and K(2,2) is

And the distance between M(-4, 2) and L(2,2) is

Therefore, the perimeter of the triangle is

Hence, Rhea travelled 16 km.

We have a table of values which contains different x-values and their related f(x).

This figure is a cylinder. The formula for its volume is:

Height (h) = 2 m,

Diameter (d) = 5 × h = 5 × 2 = 10 m; radius (r) = d/2 = 10/2 = 5 m

pi = 3.14

The volume of the cylinder is calculated as shown below:

The sum of three consecutive numbers is 111.

Consecutive Numbers: Numbers that follow each other continuously in the order from smallest to largest are called consecutive numbers. For example: 1, 2, 3, 4, 5, 6, and so on are consecutive numbers.

Let the three consecutive numbers are : x , x + 1, x +2

Since the sum of three consecutive number is 111

x + (x +1 ) + (x +2) = 111

Simplify :

x + x + 1 + x + 2 = 111

x + x + x + 1 + 2 = 111

3x + 3 = 111

3x = 111 - 3

3x = 108

x = 108/3

x = 36

So, the first number is x : x = 36

Second number is : x + 1= 36 + 1 = 37

Third Number is : x + 2 = 36 + 2 = 38

Numbers are : 36, 37, 38

Smallest number in 36, 37 & 38 is 36

Smallest number = 36

Answer : 36

Given the equation:

to write it in slope intercepept form, we have to solve for y the expression.

In this case, we have the following:

thus, the equation in slope intercept form i s y = 1/3x+6

The equation which represents the proportionality relationship is:

y=16x.

Given, we have the pairs as:

(1,16),(2,32) and (3,48)

calculate the value of y/x for the ordered pairs:

For (1,16), the value of y/x is = 16/1 = 16

For (2,32), the value of y/x is = 32/2 = 16

For (3,48), the value of y/x is = 48/3 = 16

now, compare ratios:

for each ordered pair, y/x = 16

Since, k=y/x, you know that the constant of proportionality , k is 16.

Substitute 16 for k in the equation for a proportional relationship.

y = kx

y = 16x

Hence we get the equation as y=16x.

Answer:

5 three hour classes and 27 four hour classes

Step-by-step explanation:

Convert these words into equations

Since one hour is 36, we can write two expressions for the 2 different classes: 108x and 144y (the amount of money from those classes)

x is the number of 3 hour classes, y is the number of 4 hour classes

Since the amount of money the studio makes is 4428, 108x+144y=4428

Since there are a total of 32 classes, x+y=32

So we now have the equations x+y=32 and 108x+144y=4428

Solve for x in the first equation (in order to substitute it into the second one)

we get x=32-y

plugging this into the second equation gives

108(32-y)+144y=4428

3456-108y+144y=4428

Combining like terms gives 36y=972

y=27

So there are 27 four hour classes, and 5 three hour classes( because 32-27=5)

Answer:

Step-by-step explanation:

Since all the points proportional to (2,5) follow the equation 2y = 5x, (x,y) is a solution to y=5/2x

Accordingly 2y= 5x is the same as y/x = 5/2 . Since the equation y = 5/2x is a line with y-intercept equal to 0 , there is a line which passes through points (x,y) and (2,5). The true statements are: first, third and fifth statements.

Line segment IK includes Point J. The length of the segment IK=15 and IJ=13. The length of the segment JK is 2.

Given that,

Line segment IK includes Point J.

We have to determine the length of segment JK.

We have length of the segment IK=15 and IJ=13.

Two unique points on a line define the boundaries of a line segment. A line segment is also known as a part of a line that connects two locations. A line and a line segment vary in that a line has no ends and can continue indefinitely in any direction.

We can write as,

IK=IJ+JK

15=13+JK

JK=15-13

JK=2

The meaning of the y-intercept in this situation is that: D. when the cab travels 0 miles, the total fee will be $10.00.

Mathematically, the slope of a straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

From the table, we have the following parameters:

Points (x, y) = (2, 5) and (13.00, 17.50)

Next, we would calculate the slope as follows:

Slope = (17.50 - 5)/(13.00 - 2)

Slope = 12.50/11.

Slope = 1.14.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

Where:

Substituting the given parameters into the standard equation, we have;

y - 13.00 = 1.14(x - 2)

y - 13.00 = 1.14x - 2.28

y = 1.14x - 2.28 + 13.00

y = 1.14x + 10.72

Ok, so

We have the next system of equations:

The first equation is a line, and the second one is a parable.

If we graph, we would get the following:

Then, we notice that there's two intersection points between both graphs.

These points are located at ( -1 , -3 ), and ( 2 , -6)

Therefore, there are two solutions for this problem.

x = -1 and y = -3,

x = 2, and y = -6

Now, how to graph each equation?

First one, take the line y = -x-4

Notice that this equation tells us that the line given has its intersection with y-axis at ( 0 , -4 )

We also know that a line is formed with two points, so we could replace by any "x" number and see which value "y" takes.

For example:

If x = 1,

y = -1-4, which is y = -5

So we got other point: ( 1, -5).

Now, we just join both points and we get the line, like this:

And that's how you can graph the line.

Now, how could we graph the parable?

We know that we have to take three points to join to graph a parable. So, first, we would find its intersections with x - axis, if we equal the equation to zero.

x² – 2x - 6 = 0

If we solve this equation, we obtain that x could take two different values.

To solve it, we use the next equation:

x = 1 - √7 or

x = 1 + √7.

Then, we actually have two points.

Now, finally, we could find its vertex.

If we find the vertex of the parable, we notice that it is located in (1,-7)

Now, we just join these three points as this:

And if we put these graphs together, we obtain the first graph I drew, and notice that the solution for the system is the intersection between both functions.

The scale factor here is 3 : 2.

The scale factor is defined as the difference between the new image's and the old image's sizes. A fixed point in the plane is the center of dilation. The definition of the dilation transformation depends on the scale factor and the center of dilation.

A stretched image results from a scale factor of higher than 1.

The image shrinks when the scale factor falls between 0 and 1.

The resulting image is consistent with the source image if the scale factor is 1.

As a result of the dilation modifications, the following characteristics of forms don't change:

The figure's angles are all identical.

The figure's midpoints on its sides and the midpoint of the dilated shape are both preserved.
