Answer:
10 is your answer for c.
Step-by-step explanation:
Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.
Subtract 3c from both sides:
3c (-3c) - 10 = 2c (-3c)
-10 = 2c - 3c
-10 = -c
Isolate the variable, c. Divide -1 from both sides:
(-c)/-1 = (-10)/-1
c = -10/-1
c = 10
c = 10 is your answer.

A student has gotten the following grades on his tests. What is the minimum grade he must get on the last test in order to have an average of 82? 85, 90, 79, 72
Answer:
84
Step-by-step explanation:
Because average is basically the mean, so i used a mean calculator and put in the four grades (numbers) and got an average of 81.5, so then i kept putting an additional other number in and wasn't getting 82, until i put in 84 and all of those numbers together gave me an average of 82.
Answer:
84
Step-by-step explanation:
The average is found by adding all the scores together and dividing by the number of scores
Let the unknown score be x
(85+90+79+72+x) /5 = 82
Multiply each side by 5
(85+90+79+72+x) /5*5 = 82*5
(85+90+79+72+x) = 410
Combine like terms
326+x = 410
Subtract 326 from each side
326+x-326 = 410 -326
x =84

Which relation is a function?
Answer:
The second one
Step-by-step explanation:
Choice B shows each input going to exactly one output. Therefore it is a function.
Choices A, C, and D have one input leading to more than one output. For example, the input -5 in choice C goes to more than one output (-2 and 3). This is why choices A, C, and D are not functions.
You rearrange your bedroom. Tell whether each move is an example of
a translation.
a. You slide your bed 1 foot along the wall.
b. You move your desk and chair to the opposite wall.
c. You move your bed stand to the other side of the bed.
Answer:
translation,reflection,
Step-by-step explanation:
because you move thing in different direction
Sliding the bed and moving the desk and chair are examples of translation, while moving the bed stand is an example of reflection.
a. Sliding the bed 1 foot along the wall is an example of a translation. The bed is moved from one position to another without changing its orientation.
b. Moving the desk and chair to the opposite wall is also an example of a translation. The desk and chair are moved from one side of the room to the other without any rotation or change in shape.
c. Moving the bed stand to the other side of the bed is not a translation, but a reflection. The bed stand is flipped across a line of symmetry, changing its orientation.

Jessie is considering a purchase of a $135,000 home at 5.5%. Under this rate,
her mortgage payment would be $766.51. If she purchases a point, her new
mortgage payment is $755.96. How many months would it take her to break-
even on the points purchase?
A. 244 months
B. 186 months
C. 128 months
D. 134 months
Answer: 128 months
Step-by-step explanation:
Final answer:
Jessie will break even on the point purchase for her mortgage in approximately 128 months, as a point costs 1% of the $135,000 home, and the monthly mortgage payment falls by $10.55 after purchasing the point.
Explanation:
The student is asking how many months it will take Jessie to break even on the purchase of a point for her mortgage. A point typically costs 1% of the loan amount, and in return, the lender reduces the interest rate on the mortgage. In this case, the monthly payment is reduced from $766.51 to $755.96, a monthly savings of $10.55 ($766.51 - $755.96).
To calculate the break-even point in months, divide the cost of the point by the monthly savings. If a point costs 1% of the $135,000 home, then the cost is $1,350 ($135,000 * 0.01). The number of months to break even is therefore $1,350 / $10.55, which equals approximately 128 months.
Therefore, the correct answer would be:
C. 128 months

Graph the equation
y=2(x+1)(x-1)
To graph the equation y = 2(x+1)(x-1), we can start by finding the x-intercepts and y-intercept of the equation.
To find the x-intercepts, we set y = 0 and solve for x:
0 = 2(x+1)(x-1)
0 = 2(x^2 - 1)
0 = 2(x+1)(x-1)
So, the x-intercepts are -1 and 1.
To find the y-intercept, we set x = 0 and solve for y:
y = 2(0+1)(0-1)
y = -2
So, the y-intercept is -2.
Now, we can plot the intercepts on the coordinate plane and sketch the graph of the equation. Since the equation is a quadratic function, the graph will be a parabola.
The x-intercepts are -1 and 1, so we can plot these points on the x-axis. The y-intercept is -2, so we can plot this point on the y-axis.
Next, we can plot a few additional points to help us sketch the graph. For example, we can choose x = -2, -0.5, 0.5, and 2, and find the corresponding y-values:
When x = -2, y = 2(-2+1)(-2-1) = 6
When x = -0.5, y = 2(-0.5+1)(-0.5-1) = 1.5
When x = 0.5, y = 2(0.5+1)(0.5-1) = -1.5
When x = 2, y = 2(2+1)(2-1) = 6
Now, we can plot these points and sketch the graph of the equation, which is a parabola that opens upwards and passes through the points (-2, 6), (-1, 0), (0, -2), (1, 0), and (2, 6).
The graph of the equation y = 2(x+1)(x-1) is shown below:
Graph of y = 2(x+1)(x-1)
Therefore, this is the graph of the equation y = 2(x+1)(x-1).

On a certain hot summer's day, 163 people used the public swimming pool. The daily prices are $ 1.50 for children and $ 2.50 for adults. The receipts for admission totaled $ 312.50 . How many children and how many adults swam at the public pool that day?
Answer: 95 children, 68 adults
Step-by-step explanation:
Let the number of children be y
Let the number of adults be z
The following equation can be gotten from the question:
y + z = 163 ...... equation i
1.5y + 2.5z = 312.5 ....... equation ii
Multiply equation I by 1.5
Multiply equation ii by 1
1.5y + 1.5z = 244.5 ......... equation iii
1.5y + 2.5z = 312.5 ........ equation iv
Then subtract equation iv from iii
-z = -68
z = 68
From equation I
y + z = 163
y = 163 - 68
= 95
95 children and 68 adults swam.

Answer:
It seems like there might be a bit of a mix-up or incomplete information in your question. "sin 8 =" appears to be incomplete, and "gº C." is not clear in the context provided. If you have a specific question or need assistance with a math or physics concept, please provide more details, and I'll be happy to help.

The given sine value of 2/1 is not possible as the sine of an angle cannot exceed 1 or be less than -1. It seems there's an error in your question and incomplete information prevents a comprehensive answer.
Explanation:Given that the sin 8 = 2/1, it's important to note that in a range of -1 and 1, the sine of an angle cannot be greater than 1 or less than -1. Therefore, there's an error in your original question. Also, the second part of your question seems to be cut off (gº C. 1 IN NI).

Can you answer these questions? Im doing them on my own but I need to check if they're right
Answer:
I got you.
Step-by-step explanation:
1. If x=5, whats (10x-5)+30:
First, (10x-5)
50-5=45
45+30=75
10x-5+30=75.
2.Inverse operations: 10+5 inverses 10-5, 10*5 inverses 10/5
3. I do: For example: 10x-5=60
Then, you would divide: 60/10 and 10/10
We need to isolate the variable: x-5=6
Leaving x to be 11.
4. That is a hard one but, for an equation to have no solution is that it is impossible to answer or just doesn't have an answer. And for an equation to have infinite solutions it means that it has more than one answer... Infinitely.
5. Using the distributive property for simplify: The distributive property of multiplication is a very useful property that lets you simplify expressions in which you are multiplying a number by a sum or difference. The property states that the product of a sum or difference, such as 6(5 – 2), is equal to the sum or difference of the products – in this case, 6(5) – 6(2).Remember that there are several ways to write multiplication. 3 x 6 = 3(6) = 3 • 3 • (2 + 4) = 3 • 6 = 18.
Find an explicit formula for the geometric sequence 120, 60, 30, 15, ...
Final answer:
The explicit formula for the geometric sequence 120, 60, 30, 15, ... is an n = 120 times [tex](0.5)^{n-1}[/tex], where an is the nth term of the sequence.
Explanation:
The sequence given, 120, 60, 30, 15,..., is an example of a geometric sequence where each term is obtained by multiplying the previous one by a constant called the common ratio. For this sequence, the first term a is 120, and the common ratio r is 0.5 since each term is half the preceding one.
An explicit formula for a geometric sequence can be expressed as:
an = a times [tex]r^{n-1}[/tex]
Where a is the first term, r is the common ratio, and n is the term number. Applying this to the given sequence, the explicit formula is:
an = 120 times [tex](0.5)^{n-1}[/tex]
This formula represents the nth term of the sequence, showing how each term can be calculated directly from its position in the sequence.
