So the answer has to be one of those
Explanation:
Use the intersecting chords theorem to find x
JN*NK = MN*NL
(3x+6)*16 = (7x-11)*14
48x+96 = 98x-154
96+154 = 98x-48x
250 = 50x
50x = 250
x = 250/50
x = 5
This means,
JN = 3x+6 = 3(5)+6 = 21
JK = JN+NK = 21+16 = 37

1. We know if just one dimension of a 3-D figure is 4 times longer, the volume is 4 times longer. If all three dimensions change to be 4 times longer, how many times larger is the volume?
Using proportions, it is found that the volume is 64 times larger than the volume of the original figure.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, each of the 3 dimensions will be four times greater, hence, the change in the volume will be given by:
V = 4³ = 4 x 4 x 4 = 64.
The volume is 64 times larger than the volume of the original figure.

Answer:
-3 = -5
-2= -4
-1= -3
0= -2
1 =.-1
Step-by-step explanation:
From the input -2 and from the output -4,
we can make an equation,
-2 + x =-4
or, x= -4 +2
or, x = -2
Again,
From the input 1 and output -1,
We can make an equation,
1 + x = -1
or, x= -1 -1
or, x= -2
Therefore, we know that x = -2
Now, putting the value of X in the following equations, we get,

Which inequality is represented by the graph?
Answer:
The correct option isn't shown on the image. I have attached a DESMOS graph with the option listed, and added an approximate equation that comes close to the actual line. This should aid in understanding the equations and lines.
Step-by-step explanation:
See attached image.
The one option is noted as the first equation. I added two points from the line provided: (0,-2.5) and (3.5,0) and then approximated an equation that comes closer. I simply chose 3x-4y=>10, and it comes close to the actual line that goes through the two given points.
To do this properly, find the equation, y=mx+b, of the given line using the two points selected:
Slope, m is rise/run:
Rise = 2.5
Run = 3.5
Slope = 2.5/3.5
y-intercept, b, is -2.5
The equation of the given line is y = (2.5/3.5)x - 2.5
We can rewrite this in the form the answer options are given, or rearrange the answer options to standard form in order to make the comparison.
Hopefully this will help guide to the correct solution.

Which probabilities are correct? select two options. p(a|c) = two-thirds p(c|b) = startfraction 8 over 27 endfraction p(a) = startfraction 31 over 59 endfraction p(c) = three-sevenths p(b|a) = startfraction 13 over 27 endfraction
Probability of an event is the measure of its chance of occurrence. The correct probabilities are:
P(A|C) = 2/3P(C) = 3/7How to interpret conditional probabilities?Suppose that the sample space is S. Out of which there are two events, A and B, subsets of S.
Then, we can interpret P(A|B) as the probability of that part of A which is in B, with the new sample space as B. (assuming probabililty of B isn't 0).
Symbolically, we write it as:
[tex]P(A|B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
What is the size of the union of three sets?For three sets, A, B and C:
[tex]n(A \cup B \cup C) = n(A) + P(B) + P(C) - n(A\cap B) - n(A \cap C) - n(B \cap C) + n(A \cap B \cap C)[/tex]
The problem is incomplete. The corresponding venn diagram is attached below.
We can symbolize the venn diagram as:
[tex]n(A) = 12+8+6+5 =31\\n(B) = 11+8+5+3 = 27\\n(C) = 4+8+6+3 = 21\\n(A \cap B) = 5+8=13\\n(B\cap C) = 3+8=11\\n(A \cap C) = 6+8=14\\n(A \cap B \cap C) = 8[/tex]
S = sample space = collection of all unique elements.
S is union of A, B and C.
[tex]n(S) = n(A \cup B\cup C) = 31 + 27 + 21 -13-11-14+8 = 49[/tex]
Checking all the options for their correctness:
P(A|C) = 2/3We have:
[tex]P(A|C) = P(A\cap C)/P(C) = \dfrac{n(A\cap C)/n(S)}{n(C)/n(S)} = \dfrac{n(A \cap C)}{n(C)} = \dfrac{14}{21} =\dfrac{2}{3}[/tex]
Thus, its correct.
P(C|B) = 8/27[tex]P(C|B) = P(C\cap B)/P(B) = \dfrac{n(C\cap B)/n(S)}{n(B)/n(S)} = \dfrac{n(C \cap B)}{n(B)} = \dfrac{11}{27} \neq \dfrac{8}{27}[/tex]
Thus, this option is incorrect.
[tex]P(A) = \dfrac{n(A)}{n(S)} = \dfrac{31}{49} \neq \dfrac{31}{59}[/tex]Thus, this option is incorrect.
P(C) = 3/7[tex]P(C) = \dfrac{n(C)}{n(S)}= \dfrac{21}{49} =\dfrac{3}{7}[/tex]
Thus, its correct.
P(B|A) = 13/27[tex]P(B|A) = P(B\cap A)/P(A) = \dfrac{n(B\cap A)/n(S)}{n(A)/n(S)} = \dfrac{n(B\cap A)}{n(A)} = \dfrac{13}{31} \neq \dfrac{13}{27}[/tex]
Thus, this option is incorrect.
Thus, the correct probabilities are:

What expression represents the value of x?
Ox= ww+z)
Ox=vZ(w+z)
=
Ox=/wy
Ox=WZ
ſ
Answer:
A
Step-by-step explanation:
using the altitude- on- hypotenuse theorem
( leg of large Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse ) , so
x² = w × (w + z) = w(w + z) ← take square root of both sides
x = [tex]\sqrt{w(w+z)}[/tex]
The expression that represents the value of 'x' will be x = √[w(w + z)]. Then the correct option is A.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
The triangles ΔABC and ΔBCD are similar triangles. Then the ratio of the corresponding sides will be constant.
Then the equation is given as,
x / (w + z) = w / x
Simplify the equation for 'x', then the equation is written as,
x / (w + z) = w / x
x² = w × (w + z)
x = √[w(w + z)]
The expression that represents the value of 'x' will be x = √[w(w + z)]. Then the correct option is A.

The second function has been shifted 1 unit to the left and 2 units down, which have an axis of symmetry at x = -1.
The third function has been shifted 2 units to the right and 1 unit down, which have an axis of symmetry at x = 2.
The fourth function has been shifted 2 units to the left and 1 unit down, which have an axis of symmetry at x = -2.
As you can see, the last function has been shifted 2 units to the left, which has an axis of symmetry at x = -2.

Answer:
Given:
Total horses tested = 140Horses that had Lyme disease = 42Horses that had arthritis = 112Let x = number of horses that had BOTH Lyme disease and arthritis.
⇒ (112 - x) + (42 - x) + x = 140
⇒ 154 - x = 140
⇒ x = 14
Therefore, place 14 in the middle overlapping area.
To find the number to place in the left section: 42 - 14 = 28
To find the number to place in the right section: 112 - 14 = 98

• What is the solution of 5y + 2 = 42?
y=
Answer:
y = 8
Step-by-step explanation:
Hi there!
We are given the equation 5y + 2 = 42
And we want to solve it for y
To do that, we need to isolate the variable y on one side - we don't want any numbers on the same side as y.
So we need to first get rid of any numbers on the same side as y; we can subtract 2 from both sides to remove it from the left side.
5y + 2 = 42
-2 -2
_______________
5y = 40
Now, we have variables on one side and numbers on another, but we're not done yet, as we want the value of just y, not 5y (that's 5 * y)
So to find the value of just y, divide both sides by 5
5y = 40
÷5 ÷5
________
y = 8
