Solve for x
-18 = 9 - 3x
Answer:
3x=9+18
=27
x =27÷3
x=9
the answer of x is 9
Rewrite the equation so that the x term is on the left:
9 - 3x = -18
Move the number to the right and change the sign:
-3x = -18 - 9
-3x = -27
Change the sign of both terms:
3x = 27
Move the 3 to the right and change the sign:
x = 27 ÷ 3
x = 9 is your answer.

1.) Dependent Variable:A dependent variable is almost always the [tex](y)[/tex] variable. This also means it depends on another variable. The way you can tell it's dependent for this problem is that the per the rule: distance = time. This means that the distance changes based on the time. [tex](y)[/tex] depends on [tex](x)[/tex]So your answer is Distance.

There are 12 rolls of film in a box, and 4 are defective. Two rolls are to be selected, one after the other, sampling without replacement. What is the probability of selecting two defective rolls?
Group of answer choices
None of the answers is correct.
7/23
12/132
16/144
1/4
12/144
Using the hypergeometric distribution, it is found that the probability is 12/132
------------------------------------
The rolls are chosen from a sample without replacement, which means that the hypergeometric distribution is used to solve this question.
------------------------------------
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
------------------------------------
12 rolls means that [tex]N = 12[/tex]4 defective means that [tex]k = 4[/tex]2 are chosen, which means that [tex]n = 2[/tex]------------------------------------
What is the probability of selecting two defective rolls?
This is P(X = 2). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,4) = \frac{C_{4,2}*C_{8,0}}{C_{12,2}} = \frac{4 \times 3}{12 \times 11} = \frac{12}{132}[/tex]
12/132 is the probability.

There are 5 times as many orange popsicles as grape popsicles in Reid's freezer. There are 12 more orange popsicles than grape popsicles. How many grape popsicles are there in Reid's freezer?
Answer:
3 grape popsicles
Step-by-step explanation:
Let us represent
Orange popsicles = x
Grape popsicles = y
There are 5 times as many orange popsicles as grape popsicles in Reid's freezer.
x = 5y ..... Equation 1
There are 12 more orange popsicles than grape popsicles.
x = y + 12..... Equation 2
Hence, we substitute 5y for x in Equation 2
5y = y + 12
5y - y = 12
4y = 12
y = 12/4
y = 3
Note that, Grape popsicles = y
y = 3 grape popsicles.
Therefore, the number of grape popsicles that are there in Reid's freezer is 3 grape popsicles

Write the slope-intercept form equation of a line that goes through the point (4, -4) and is parallel to y = -7x + 5.
Answer:
y=7x-32
Step-by-step explanation:
Since the line is parallel to y=-7x+5, it will have the same slope
use the slope-intercept form to find b, y=7x+b
plug the points into the equation
(-4)=7(4)+b
simplify
-4=28+b
subtract 28 from both sides
b= -32
plug b into the equation
y=7x-32

[tex]s^2.t^2[/tex]
Step-by-step explanation:
Like Terms
To be considered similar or like terms, two or more terms must have the exact same variables with the exact same exponents, regardless of the coefficients. For example, the following are like terms:
[tex]x, 5x, -3x, 2/5x[/tex]
[tex]3ab^2, -1/2ab^2, 7b^2a[/tex]
The following are not like terms:
[tex]x, 3y, -x^3[/tex]
[tex]pq^3, p^3q^3, -p^3q[/tex]
We need to find which of the given terms are not considered to be like terms with the expression [tex]-6s^2t[/tex]. The variable s must be squared and the variable t must have an exponent of 1.
Applying the above definition, the following expressions are not like terms:
[tex]4(s.t)[/tex]
[tex]-6(s^2+t)[/tex]
[tex]s^2.t^2[/tex]
Answer:

i need to find the measure of angle L
Answer:
Angel L = 52°
Step-by-step explanation:
In ∆ JKL,
J = 8x + 6°
K = 2x + 2°
L = 4x+ 4°
L =?
Let's solve this question with the help of Angle Sum Property of a Triangle (ASPT).
We know that all angles in a triangle add up to 180°.
180 = ∆JKL
180 = J + K + L
180 = (8x + 6) + (2x + 2) + (4x + 4)
180 = 8x + 6 + 2x + 2 + 4x + 4
180 = 8x + 2x + 4x + 6 + 2 + 4
180 = 14x + 12
14x = 180 - 12
14x = 168
x = 168/14
x = 12°.
Now, L° = 4x + 4
= 4(12) + 4
= 48 + 4
= 52°.

You need to multiply the numerator and denominator by the conjugate of
2 + 5i, which is 2 - 5i
So, [tex]\frac{(1 - 3i)(2 - 5i)}{(2 + 5i)(2 - 5i)} = \frac{2 - 11i - 15}{4 +25} = \frac{-13 - 11i}{29}[/tex]
Aviation:
An airplane goes down from 42,000 feet to 18,000 feet in 12 minutes. What is the rate of change of the altitude in feet per minute?
Change in altitude:
42,000 - 18,000 = 24,000 feet
Rate of change = 24,000 feet / 12 minutes = 2,000 feet per minute
Because the plane was going down, the rate of change would be negative.
The rate would be -2,000 feet per minute.
Regular pentagon MNQR similar to pentagon TUVWX. What scale factor was used dilate regular pentagon MNPQR to Pentagon TUVWX?
Answer:
. Since the pentagon is a regular pentagon, the measure of each interior angle will be the same.
To find the size of each angle, divide the sum, 540º, by the number of angles in the pentagon.
(which is the same as the number of sides).
540° ÷ 5 = 108° There are 108° in each interior angle of a regular pentagon.
2. 540°
Sum of Interior Angles of a Polygon
A pentagon has five sides, thus the interior angles add up to 540°, and so on.

Factor out the gcf
-240c^2+ 30c^5+ 18c^4
Answer:
6c^2(-40 + 5c^3 + 3c^2)
Step-by-step explanation:
These three terms have the common factor c^2. Thus:
-240c^2+ 30c^5+ 18c^4 = c^2(-240+ 30c^3+ 18c^2).
Recognizing that 6 is common to all three terms inside the parentheses, we get:
6c^2(-40 + 5c^3 + 3c^2) This is as far as factoring of this expression can be taken.

Lola's hair today is 24" long. It grows 1.5" per month. She is a pretty tall girl for her age, about 60" right now! Her brother has long hair too. His hair is about 12" long. What does the y stand for?
If I'm correct, you're asking which variable is the dependent variable y from the question
Answer and explanation:
The equation can be modelled:
y= 1.5x
Where y is the current length of the hair
x is the number of months of hair growth
We can see from the equation therefore that y is a dependent variable that depends on x the independent variable, the number of months, to get a value. In other words given that her hair grows at a constant rate of 1.5 inches per month, her hair length is based on number of months x of growth in inches of hair.
