Answer:
i finished on the other question yw
Step-by-step explanation:
also not sure if you wanted the values for n
edit:
7. n/2 = 16
8. 2n + 4 = 52
9. 2(n + 5) = 17
10. 3n - 12 = 5
Answer:
7. 32
8. 24
9. 3.5
10. 5.6
Step-by-step explanation:
7. write the equation: n/2=16. Cross multiply.
8. write the equation: 52= 4+2n. Move 4 to the other side and subtract from 52: 48= 2n. Divide both sides by 2.
9. write the equation: 2(5+n)=17. Use the distributive property. Move 10 to the other side and subtract from 17: 2n=7. Divide both sides by 2.
10. write the equation 3n-12=5. move -12 over and add to 5: 3n=17. Divide both sides by 3.

Hi! I'm happy to help! (sorry for the wait, my computer crashed)
A linear function is where one variable is independent (x), and another is dependent. This means that we use x to solve for y, y depends on x to be found.
To solve this, we use an equation call slope intercept form, which states that y=mx+b.
There is only 1 solution line. (to solve for how to find y, you only have to have two verifications)
For our first table, we have x as 1, 2, 3,and 4. y is 3, 6, 12, and 24.
For our first set, with x is one and y is 3, there are infinite solutions, so we have to test and see if it matches the second set of x is 2 and y is 6.
How I like to check for what m will be, I check the first two y values. The first two are 3 and 6. They have an increase of 3, so m will be 3. (this only works when x increases by 1)
With m being 3, we can solve for b, to complete the equation:
3=(3(1))+b
3=3+b
With this, b must equal 0
3=3+0
Now, we just have to check if this equation matches all of the other x values:
6=(3(2))+0
6=6+0
__________________________________
12=(3(3))+0
12=9+0
12≠9
This equation doesn't seem to work, so this is not a linear function.
For our next table, our first two y values are 2 and 5, which have a increase of 3, so our m will be 3 again.
Now, let's solve for b:
2=(3(1))+b
2=3+b
In this case, b will be -1 because 2=3-1
Now, let's check if this matches up with our other values:
5=((3)2)-1
5=6-1
_______________________________
9=((3(3)-1
9=9-1
9≠8
This equation doesn't work, so it is not a linear function.
For our next table, we have our first two y values as -3, and -5. This has a decrease of 2, so our m will be -2.
Now, let's solve for b:
-3=((-2)1)+b
-3=-2+b
In this equation, b will be -1 because -3=-2-1.
Now, let's check our other values:
-5=(-2(2))-1
-5=-4-1
___________________________________________
-7=(-2(3))-1
-7=-6-1
______________________________________________
-9=(-2(4)-1
-9=-8-1
All of these values match, so this is a linear function.
If you wanted to (you don't have to, but if you needed verification) you could check the fourth problem.
Has a decrease of 2, so m would be -2. Plug it in:
-2=(-2(1))+b
-2=-2+b
b would be 0.
Check it on the second problem:
-4=(-2(2))+0
-4=-4+0
Check the third:
-2=(-2(3))+0
-2=-6+0
-2≠-6
The fourth table doesn't match either, so it is not a linear function.
You should choose option 3 because it is a linear function.
I hope this was helpful, keep learning! :D

Answer: 36/a^2b
Step-by-step explanation:
Starting with the question 4a^3b^-2*9a^-5b
Since we have multiplication we multiply our numbers and add exponents
So
4*9=36
and exponents
3+-5=-2
-2+1=-1
So 36a^-2b^-1
BUTTT because we absolutely CANNOT have negative exponents we put them in the denominator to make them positive so our final answer is
[tex]\frac{36}{a^2b}[/tex]

A sphere with surface area of 154cm² is fit exactly in cubical box, Use π 22/7
what is the volume of the box A.147
B.154
C.216
D.343
Answer:
Answer :-Surface area of sphere = 4 π r²
154 = 4 × 22/7 × r²
154 = 88/7 × r²
154 × 7/88 = r²
12.25 = r²
3.5 = r
Now
Volume of sphere = 4/3 × π r³
Volume = 4/3 × 22/7 × (3.5)³
Volume = 88/21 × 42.875
Volume = 154 cm³
Volume of sphere = Volume of cube
Volume of cube = 154 cm³

A music club was formed in the month of January last year. The function m(t) = t2 - 4t + 25 models the number of club members for the first 10 months, where t is the number of months since the club's inception. Complete the square, and graph this function. What is the minimum number of members the club had during the year? A. 29 members B. 24 members C. 22 members D. 21 members
Answer:
D
Step-by-step explanation:
We have to find the vertex of m(t) = t² - 4t + 25
a = 1
b = 4
c = 25
To do that we first need to move the 25 to the other side by subtracting 25 from both sides
m(t) = t² - 4t + 25
- 25 - 25
m(t) - 25 = t² - 4t
To continue completing the square, we have to add 4 to both sides since it is the square of half of b.
m(t) - 25 + 4 = t² - 4t + 4
m(t) - 21 = t² - 4t + 4
Now, we already found the minimum amount of members, but let's finish the square completion to find the vertex.
m(t) - 21 = t² - 4t + 4
Factor the right side
m(t) - 21 = (t-2)(t-2)
m(t) - 21 = (t-2)²
Finish it by adding 21 to both sides
m(t) - 21 = (t-2)²
+ 21 +21
m(t) = (t-2)² + 21
With this vertex form equation, we can tell that the vertex is (2,21)
Meaning 21 is the lowest number for m(t) for this equation.

3 Sean has 8-inch pieces of toy train track and Ruth has 18-inch pieces of train track. How
many of each piece would each child need to build tracks that are equal in length?
Answer Statements:
Answer:
72
Step-by-step explanation:
The smallest number that is divisible by two given numbers is called the Least Common Multiple (LCM) of those numbers.
What's the smallest number that is a multiple of 8 and also a multiple of 18?
One way to find out is to start making lists of multiples:
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, and so on,
Multiples of 18: 18, 36, 54, 72, 90, 108, and so on.
This method can be a bit tedious, but in this case, it's clear that 72 is the LCM of 8 and 18.
Another method is to use the prime factorization of the two numbers.
Write 8 and 18 as the product of prime numbers; each number has a unique prime factorization.
8 = 2 x 2 x 2 = 2^3
18 = 2 x 3 x 3 = 2^1 x 3^2
To form the LCM, build a product of primes using the highest exponent in either of the two numbers.
LCM = 2^3 x 3^2 = 8 x 9 = 72.
Robert says that the slope of a line passing through (1, 7) and (3, 9) is equal to the ratio 1-3/7-9 . Is this a correct method for calculating the slope? Explain your answer. (1 point)
Answer:
The slope should be calculated using the formula [tex](7 - 9) / (1 - 3)[/tex] instead of the one that was proposed in the question.
Step-by-step explanation:
The slope of a line in a cartesian plane is the rate at which [tex]y[/tex] changes with respect to [tex]x[/tex].
For this line, the value of [tex]y[/tex] increased (vertically) from [tex]7[/tex] at [tex](1,\, 7)[/tex] to [tex]9[/tex] at [tex](3,\, 9)[/tex] as the value of [tex]x[/tex] increased (horizontally) from [tex]1[/tex] to [tex]3[/tex].
In other words, [tex]y[/tex] changed by [tex](9 - 7)[/tex] while [tex]x[/tex] changed by [tex](3 - 1)[/tex].
The slope of the line (rate at which [tex]y[/tex] changes with respect to [tex]x[/tex]) would be:
[tex]\displaystyle \frac{\text{rise}}{\text{run}} = \frac{(9 - 7)}{(3 - 1)} = \frac{(7 - 9)}{(1 - 3)}[/tex].
In general, for a line that goes through [tex](x_1,\, y_1)[/tex] and [tex](x_2,\, y_2)[/tex], where [tex]x_{1} \ne x_{2}[/tex]:
[tex]\begin{aligned}\text{slope}&= \frac{(y_1 - y_2)}{(x_1 - x_2)} = \frac{(y_2 - y_1)}{(x_2 - x_1)}\end{aligned}[/tex].
Find the value of x from the given figure:
Answer:
60°
Step-by-step explanation:
2x and x are linear pair,
=> 2x + x = 180
=> 3x = 180
=> x = 180/3
=> x = 60°
=>2x =120°
Answer:
x = 60
Step-by-step explanation:
x + 2x = 180 {linear pair}
Combine like terms
3x = 180
Divide both sides by 3
x = 180/3
x = 60
