The distance between the points (0, 0) and (0, 6) on the coordinate plane will be 6 units. Then the correct option is D.
What is the distance between two points?The shortest distance (length of the straight line segment's length connecting both given points) between points (p, q) and (x, y) is:
D² = (x – p)² + (y – q)²
Point M is 6 units away from the origin.
Take option D assuming correct, then the point will be (0, 6)
Then the distance between the points will be
D² = (0 - 0)² + (6 - 0)²
D² = 0² + 6²
D² = 0 + 36
D² = 36
D = 6 units
Then the correct option is D.

Part B:
Choose the correct degree measure for JKL
A. 98
B. 65.5
C. 262
D. 24.5
Answer:
x = 7 y = 4 JKL = 262 degrees
Step-by-step explanation:
According to a circle theorem, sum of the opposite angles in a circle which touch its circumference must equal 180, hence:
7x + 131 = 180
x = 7
According to another theorem, a quadrilateral inside a circle must equal 360 so:
99 + 7(7) + 131 + 11(7) + y = 360
Note: remember to substitute 7 for all values of x
y = 4
The angle subtended by an arc at the centre is twice the angle subtended at the circumference
Following this rule, we can conclude that:
2(7x) or 2(2 x 7) = 2(49) which is 98
Lastly, 360 - 98 = 262

The equation y = 1/3x - 2 passes through the diagonals of ZDRN
How to determine the end result?The points are given as:
Z = (-3, -1)
D= (3, -1)
R = (3, -3)
N = (-3, -3)
The equation of the line is given as:
y = 1/3x - 2
When the points and the line equation are plotted in a graph on the same coordinate (see attachment), we can see that the equation y = 1/3x - 2 passes through the points Z = (-3, -1) and N = (-3, -3)
These points are the diagonals of the shape formed by the four points

A company ordered $6,000 worth of chairs. Some of the chairs ordered cost $20 each and the others cost $40 each. If twice as many $20 chairs as $40 chairs were ordered, how many chairs were ordered altogether
In total 180 chairs are ordered for the cost $6000.
The total cost of chairs=$6,000.
What are simultaneous equations?In mathematics, a set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Let x be the chairs ordered each at $20 and y be the chairs ordered each at $40.
Then equation will be 20x+40y=6000-------(1)
Given that, twice as many $20 chairs as $40 chairs were ordered.
That is 2x=y⇒2x-y=0--------(2)
Multiply equation (2) by 40.
That is 80x-40y=0--------(3)
By adding equation (2) and (3) we get
20x+40y+80x-40y=6000
⇒100x=6000
⇒x=60
Substitute x=60 in equation (2)
That is, 2x=y
⇒y=120
Total number of chairs=x+y=60+120=180 chairs.
Hence, in total 180 chairs are ordered for the cost $6000.

work out the length x in the triangle
Answer:
The length x is 16 m==============
Imagine the height of the triangle is h, which is perpendicular to 15 m side.
The area is:
A = bh/2Use this formula and given values and find the value of h:
60 = 15h/2h = 60*2/15h = 8 mSince h is opposite to 30° angle and x is the hypotenuse of the formed right triangle, we'll use the property of 30°x60°x90° triangle.
Hypotenuse is twice the length of the side opposite to 30° angle.In our case h is opposite to 30° angle, therefore we have:
x = 2h = 2*8 = 16 mAnswer:
x = 16
Step-by-step explanation:
the area (A) of the triangle is calculated as
A = [tex]\frac{1}{2}[/tex] absinC
where a, b are 2 sides of the triangle and C the angle between them
here a = 15, b = x, C = 30° and A = 60 , then
[tex]\frac{1}{2}[/tex] × 15 × x × sin30° = 60
7.5x × [tex]\frac{1}{2}[/tex] = 60 ( multiply both sides by 2 to clear the fraction )
7.5x = 120 ( divide both sides by 7.5 )
x = 16
Solve |x| > -9.
1. no solution
2. all reals
3. {x | x < -9 or x > 9}
Answer:
2. All reals
Step-by-step explanation:
It covers everything as absolute value (distance from 0)
If you graph it you will see
Reason:
Absolute value represents distance on a number line. Specifically it's the distance from x to 0.
For example, |-2| = 2 means -2 is 2 units away from 0.
Since |x| represents a distance, we cannot have negative distance. So |x| is either 0 or positive. Furthermore, it means |x| is larger than any negative value you pick.
Therefore, |x| > -9 is true for any x value and it's why we go for "all reals" (aka "all real numbers")

I reallyyyy need help!!! ASAP PLEASE!!!!!
Answer:
[tex]a_{n}[/tex] = 100n - 78
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₁₄ = 1322 and a₃₈ = 3722 , then
a₁ + 13d = 1322 → (1)
a₁ + 37d = 3722 → (2)
subtract (1) from (2) term by term to eliminate a₁
24d = 2400 ( divide both sides by 24 )
d = 100
substitute d = 100 into either of the 2 equations and solve for a₁
substituting into (1)
a₁ + 13(100) = 1322
a₁ + 1300 = 1322 ( subtract 1300 from both sides )
a₁ = 22
then nth term formula is
[tex]a_{n}[/tex] = 22 + 100(n - 1) = 22 + 100n - 100 = 100n - 78

Step-by-step explanation:
This is the form of a hyperbola. Use this form to determine the values used to find vertices and asymptotes of the hyperbola.
[tex]\frac{(x-h)^2}{a^2} - \frac{(y-k)^2}{b^2} = 1[/tex]
Match the values in this hyperbola to those of the standard form. The variable h represents the x-offset from the origin, k represents the y-offset from origin, a.
a = 1
b = 3
k = 4
h = 4
Thus,

Answer: 72 inches squared
Step-by-step explanation:
So, the real floor of a classroom is 36 feet by 32 feet.
And the scale drawing, has length of the classroom equal to 9 inches.
What is the area in square inches of the floor in the scale drawing
1 foot = 12 inches
The length of the classroom, measured in feet, has been multiplied by 12, to get converted in inches. After that, it has been divided by a number, a proportion, to get to 9 inches.
36feet * 12 / x = 9 inches
432 inches / x = 9 inches
Now, to solve for x, we can cross-multiply
432 inches = 9x inches
Divide 9 inches on both sides.
x = 48
To solve the exercise, we need to calculate the floor's area in the scale drawing.
We have the length = 9 inches.
Now, let's calculate the width
Width = 32 feet * 12 / 48
Width = 384 inches / 48
Width = 8 inches
Area = Length * Width
Area = 9 inches * 8 inches
Area = 72 inches squared

Javier is comparing costs of two cars. Car A costs $130 per month for insurance and $0.10 per mile to run. Car B costs $108 per month for insurance and $0.15 per mile to run. He defines x as the number of miles driven each month and y as the total cost to run the car. Which set of equations can be used to find the number of miles Javier would need to drive to make the costs equal?
0.10 x = 130. 0.15 y = 108
y = 0.10 x + 130. y = 0.15 x + 108
0.10 x = 108. 0.15 y = 130
y = 0.15 x + 130. y = 0.10 x + 108
Answer:
y = 0.10 x + 130. y = 0.15 x + 108
Step-by-step explanation:
0.10 and 0.15 are the slope in the equation y = mx + b since it requires an input (number of miles) to spit out an output (number of miles*0.10 = price) and the x intercept is 130 and 108 creating the equation y = 0.10 x + 130. y = 0.15 x + 108.

Answer:
12
Step-by-step explanation:
A constant in an expression is the number that is not attached to any variable, and this includes the sign that comes with the number.
0.05m +12
In the expression above, m is the variable thus 0.05 is known as the coefficient of m instead of a constant. Coefficients are numbers that are multiplied to variables.
+12, which can simply be written as 12, is not multiplied to any variable and is thus the constant.
The value of the number 12 will not change no matter the value of m. The fact that the value stays the same makes it a constant.

Which of the following steps can be used to eliminate the x term?
02(x+y=8)
O-2(x+y=8)
O-1(2x + 5y = 24)
O-2(2x + 5y = 24)
Step-by-step explanation:
as the following pic answer should be × -2
Answer:
O -2(x+y=8)
Step-by-step explanation:
If you put the problems beside each other, they look like this;
2x + 5y = 24
x + y = 8
So you are trying to find a way to simplify the x's
Step 1;
See if there are any numbers that you could multiply to the bottom problem that would help you get rid of the x specifically.
In this case, -2 would cancel out that other 2 right? Because if you added them, they cancel each other out; 2 -2 = 0
Step 2:
if you multiply, you have to do it to the entire problem;
-2(x + y = 8) (-2 times x, -2 times y, -2 times 8)
-2x + -2y = -16
Step 3:
Go back to your original problem and work it out;
2x + 5y = 24
-2x + -2y = -16
2x and -2x cancel each other out so now you only have;
5y = 24
-2y = -16
Step 4:
Combine like terms;
5y = 24
-2y = -16
3y = 8
Divide by 3
y = 2.6
