Answer:
A. y = -14
Step-by-step explanation:
Subtract 9 from its self and from 23 in order to isolate -y
-y + 9 = 23
- 9 -9
0 14
-y is now Isolated.
-y = 14
Generally, when you have a letter representing a number by itself such as -y, it is indicated that therecis always a 1, example -y = -1y, x = 1x, however 3y does not equal 13y or 31y. 3y already has a number in front of it so therefore, there is no need to include the number 1 in front of y.
Because -y is the same as -1y, that is a multiplation representation. -y is the same as -1 x y so the next step is to isolate y from -1. In order to do that, you will need to divide -1 by 1 and 14 by 1. (Remember, (-) (-) = + and (-) (+) = - and (+) (+) = +.)
-y = 14
-1 -1
y = -14

The segment shown below could form a triangle. 6, 5, 8
AC 6 , CB 5, BA 8
Answer:
Yes
Step-by-step explanation:
In order to form a triangle sum of the lengths of any two sides must always be greater than the length of the third side.
Here,
6 + 5 = 11 > 8
5 + 8 = 13 > 6
8 + 6 = 14 > 5
Given side lengths satisfy above condition. Hence the given segment can form a triangle.

What is the value of x?
Answer & Step-by-step explanation:
We can use the Pythagorean Theorem to find the value of x.
[tex]a^2+b^2=c^2[/tex]
For a, we will use 3.
For b, we will use 4.
For c, that will be our x.
[tex]3^2+4^2=c^2\\9+16=c^2\\25=c^2\\\sqrt{25} =\sqrt{c^2}\\ 5=c[/tex]
So, the value of x is 5.
A blue die and a white die are tossed. Find n
Answer: Then the sample space is 36.
Step-by-step explanation:
n is the number of possible combinations.
Now, as the die are of different colors, the case where:
white = 1 blue = 2, sum = 1+ 2 = 3
white = 2 blue = 1, sum = 2 + 1 = 3
are different.
So the number of possible combinations is:
6 options for the white dice and 6 options for the blue dice, so we have:
6*6 = 36 different combinations.
Then the sample space is 36.
Simplify the expression below.

For the graph, what is a reasonable constraint so that the function is at least 200? graph of y equals minus 2 times the square of x plus 30 times x plus 200 −5 ≤ x ≤ 20 0 ≤ x ≤ 15 x ≥ 0 All real numbers
Answer:
The correct constraint is:
0 ≤ x ≤ 15
Step-by-step explanation:
The function given to us in the question is:
y = -2x² + 30x + 200
It is given that the function is at least 200, we can write is as:
-2x² + 30x + 200 ≥ 200 ⇒ Equation (i)
To find the constraint, replace ≥ sign with = sign and solve for x:
-2x² + 30x + 200 = 200
-2x² + 30x = 0
x(-2x + 30) =0
x = 0 , -2x + 30 = 0
x = 0 , -2x = -30
x = 0 , x = -30/-2
x = 0 , x = 15
So the end values of constraint are 0 and 15.
Take any value between 0 and 15 and substitute in equation (i) to see whether it satisfies the equation or not.
-2x² + 30x + 200 ≥ 200
Substitute x = 5 in the equation:
-2(5)² + 30(5) +200 ≥ 200
-50 + 120 +200 ≥ 200
270 ≥ 200
As the equation satisfies. it means that the solution lies between 0 and 15, including the end values.
Hence.
0 ≤ x ≤ 15

0 ≤ x ≤ 15

GCF stands for greatest common factor, so you need to find a common factor between 35, 14, and -7. Use a method of your choice to find the GCF and you should find that it's 7. Then, you take the 7 "out" and put parentheses around the original equation while dividing every "term" by 7.

After entering the table values in his calculator, Cory used the LinReg button
to get the results shown. Identify the correlation coefficient and the type of
correlation.
Answer:
Strong positive correlation, 0.9663
Step-by-step explanation:
The value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
The value of the correlation coefficient can be found as;
r = -0.2984713607
After rounding off we get;
r = -0.2985
As the value of r is not close to the -1 therefore, the relation between x and y is weak negative.
Hence, the value of the correlation coefficient will be; -0.2985, and the relation between x and y is a weak negative.

At the end of a year, the gross debt of a country stood at about $24 trillion. Express this amount in dollars per person, assuming that the population of the country is about 298 million
Answer: $80536.9
Step-by-step explanation:
From the question, at the end of a year, the total debt of a country stood at about $24 trillion and the country has a population of 298 million.
To calculate the amount in dollars per person, we divide the gross debt by the population. This will be:
= 24 trillion ÷ 298 million
= 24,000,000,000,000 ÷ 298 000 000
= 80536.9
The amount in dollar per person will be $80536.9
What is the next term of the following sequence?

Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2 [tex]\frac{1}{2}[/tex] ÷ 5 = [tex]\frac{1}{2}[/tex]
Thus to obtain the next term in the sequence multiply the previous term by [tex]\frac{1}{2}[/tex]
2 [tex]\frac{1}{2}[/tex] × [tex]\frac{1}{2}[/tex] = 1 [tex]\frac{1}{4}[/tex]

Our first step is to get rid of the fraction by multiplying both sides by 3.
So in our second step we have x - 4 > -36.
Now add 4 to both sides to get x > -32.
Since x is greater than -32, the values that would
make this inequality true are -31 and 31.

a. Which of these could be the area of Circle B? *
About 100 in ^2
About 300 in^2
About 900 in^2
About 2,700 in^2
b. Explain your reasoning for part a. Use the approximation of about 3 for pi. *
Answer:
D) About 2,700 in^2
Step-by-step explanation:
Equation for area of a circle is A=3r² (it would usually be A=πr² but we are using the approximation)
The diameter is 60, we want to find the radius for the equation. We can use the equation d=2r to find the radius of the circle.
60=2r
30=r
Put radius into the area equation.
A=3(30)²
A=3(900)
A=2700
Answer:
2,700 in^2 ; Option D
Step-by-step explanation:
If it is known that the diameter of Circle B ⇒ 60 inches,
[tex]Diameter - 60 inches,\\\\Radius - 60 / 2 = 30 inches,\\\\Area of Circle B ( \pi stands for 3 ) - \pi * ( r )^2 = ( 3 ) * ( 30 )^2 = ( About ) 2,700 square inches\\\\Solution; 2,700 square inches[/tex]

The number is in scientific notation.
No, it is not in scientific notation. The number is not written as a product of 2 factor
No, it is not in scientific notation. The first factor is not less than 10.
No, it is not in scientific notation. The first factor is not greater than or equal to 1.
Answer:
No, it is not in scientific notation. The first factor is not greater than or equal to 1.
Step-by-step explanation:
Scientific notation is a method of writing numbers as the product of two factors where the first factor is a number whose absolute value is greater than or equal to 1 but less than 10.
Answer:
last option
Step-by-step explanation:
In scientific notation the number being multiplied by the power of 10 has to be in between 1 and 10, and since 0.11 doesn't satisfy this the answer is it is not in scientific notation because the first factor is not greater than or equal to 1.

A tree house is 10 feet up in a tree. A ladder that leans against the tree and
leads to the tree house door is 12 feet long. How far away from the base of
the tree is the bottom of the ladder? Draw a picture and solve. Round your
answer to the nearest tenth.
Answer:
6.63 ft
Step-by-step explanation:
In this case we use pythagora's theorem which is
[tex]hyp^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]opp^{2}[/tex]
in this case, the hypotenuse (hyp) is the length of the ladder, the opposite (opp) is the height of the tree house and, the adjacent (adj) is the distance of the ladder's bottom to the base of the tree.
hpy = 12 ft
opp = 10 ft
adj = ?
substituting into the equation above, we have
[tex]12^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]10^{2}[/tex]
144 = [tex]adj^{2}[/tex] + 100
144 - 100 = 44 = [tex]adj^{2}[/tex]
the image is shown below
adj = [tex]\sqrt{44}[/tex] = 6.63 ft
Two boys, starting at the same point, walk-in opposite directions for x meters, turn right and walk another y meters, and turn right and walk another x meters. What is the distance between them?
Answer:
2y meters
Step-by-step explanation:
The first x meters are cancelled with the last x meters because after turning right two times they walk in the opposite direction that each of them started to walk.
The y meters each of them walk are also in the opposite direction, so given that each of them walked y meters, the distance between them is 2y meters.
