Answer:

∴ x = 32

Step-by-step explanation:

For J to be parallel to K,

(2x)° + (4x-12)° = 180°

   2x + 4x - 12 = 180

                  6x = 192

                 ∴ x = 32

According to the given coordinates, there are 4 set of points will appear on the Kelsey’s graph and the graph is attached below.

Coordinates refers the locations of points on a grid known as the cartesian plane or coordinate plane.

Given,

Kelsey is going to graph the ordered pairs that are represented by this table on a coordinate plane.

Here we need to find the number of points should appear in Kelsey’s graph.

In order to find the number of points, first we have to plot the table vales on the graph.

Once we plotted the values on the graph then the graph is look like the following graph.

While we looking through the graph we have identified that the points are (-6,-4), (-4, -6), (3, -6) and (5, 0) are presented on the graph.

The value are x=1,y=3 and z=-1 when the equation are x+5y-3z=19, 2x-3y+4z=-11 and 4x+y-2z=9.

Given that,

The equation x+5y-3z=19

2x-3y+4z=-11

4x+y-2z=9

We have to find the x,y ad z values. Its is nothing but the zeros of the polynomial.

Take the equations as,

x+5y-3z=19----->equation(1)

2x-3y+4z=-11----->equation(2)

4x+y-2z=9----->equation(3)

Subtracting equation (2) with 2×equation(1)

What is unitary method?

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Steps to Use Unitary Method

First, let us make a note of the information we have. There are 5 ice-creams.

5 ice-creams cost is $125.

Step 1: Let's find the cost of 1 ice cream.

In order to do that, divide the total cost of ice-creams by the total number of ice-creams.

The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-

creams = 125/5 = 25.

Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams.

The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75.

Finally, we have the cost of 3 ice-creams i.e. $75.

lemonade: tea : total

1                 1    1+1=2

We need a total of 16 and divide it

= 16/2 = 8

Then the composition will be

lemonade:    tea:        total

1*8 = 8      1*8 = 8      2*8 = 16

Hence, 8 cups of lemonade are needed.

The pair of polygons in the diagram are not similar.

What are polygons?

A closed polygonal chain made up of a finite number of straight-line segments is what defines a polygon in geometry. A polygon can be defined as a region that is circumscribed by a bounding circuit, a plane, or both. The edges or sides of a polygon circuit are its segments.

Solution Explained:

Similar polygons have proportional matching sides and all corresponding angles that are congruent.

Since the polygons' side lengths ensure that they are parallelograms, the congruence of just one pair of related angles is sufficient to guarantee the congruence of all the others.

The ratio of side lengths in the left polygon is 13/8, whereas in the right polygon it is 5.2/2.4, which equals 13/6. The matching sides are NOT proportionate since their ratios are different from one another.

Hence, the pair of polygons are not similar.

A parabola that have a focus of (7,3) and a directrix of y = 5 has these attributes

The parabola is a vertical parabola and facing down

the vertex of the parabular is v(7, 4)

p value of the parabola = -1

A parabola refers to  shape that traces equation of the form

ax² + bx + c

The directrix of a parabola refers to a vertical or horizontal line that never touches the parabola and at distance p to the vertex of the parabola., and 2p to the focus of the parabola.

when the directrix is on the y coordinate, the parabola formed is a vertical parabola.

If the value of the directrix is more than the corresponding focus or vertex there will be negative p and the parabola will face downward.

conversely, If the value of the directrix is less than the corresponding focus or vertex there will be positive p and the parabola will face up.

from definition of the directrix we calculate for p

2p = y coordinate of focus - equation of directrix

2p = 3 - 5

2p = -2

p = -1

What is Logarithm?

The logarithm is exponentiation's opposite function in mathematics. This indicates that the exponent to which b must be raised in order to obtain a number x is the logarithm of x to the base b. For instance, because 1000 = 103, the logarithm of 1000 in base 10 is 3, or log10 = 3.

Given that;

log6 36

Formula we used to solve this logarithm equation is :

According on the value of another variable, a variable's value can be predicted using a linear regression analysis. The dependent variable is the one you're trying to forecast. The term "independent variable" refers to the variable you are using to forecast the value of the other variable.

Main Body:

For linear regression

Y=a + bx + error

If we neglect error

then Y=a + bx.

If x increases by 1

What are Time and Work?

According to fundamental mathematical concepts, time may be described as the amount of time that a specific activity occurs, whereas work can be described as the collection of actions carried out in order to attain a specific activity or outcome. It should go without saying that time is needed to accomplish a task. It implies that time and work have a certain relationship.

The task completed is calculated as the sum of the number of people participating in the work and the number of days it took to finish. The fundamental time and work equation is W = N X D.

W is the amount of work done.

N is the number of people.

D is the number of days or hours needed.

Let r be the regular rate and h the holiday rate.

Then you can write these two equations:

From the first statement:

188.50 = 5h + 16r

From the second statement:

254.00 = 8h + 20r.

There you have a system of two independent equations with two variables, which you can solve by several methods.

If you multiply the first by 8 and the second by 5, you get:

40h + 128r = 1508

40h + 100r = 1270

Subtract the second equation from the first one:

28r = 238

Divide by 28

r = 238/28 = 8.5

You can use now any of the two original statements to find h

254.00 = 8h + 20r

8h = 254 -20(8.5) = 84

h = 84/8 = 10.5

h - r = 10.50 - 8.50 = 2.00

The holiday hourly rate is $2.00 more than the regular hourly rate.
