Answer:
easy the answer is d)y=2
Step-by-step explanation:
why because
3y−4=6−2y
Add 2y to both sides.
3y−4+2y=−2y+6+2y
5y−4=6
Add 4 to both sides.
5y−4+4=6+4
5y=10
Divide both sides by 5.
5y/5 = 10/5
y=2

What is the distance from QR?
Q
6n + 3
s
4n + 11
R
Answer:
The distance of QR is 54 units
Step-by-step explanation:
In the isosceles triangle, The height drawn from the vertex angle to the base bisects the base
In ΔPQR
∵ PQ = PR
∴ Δ PQR is an isosceles triangle
∵ P is the vertex angle
∵ QR is the base
∵ PS ⊥ QR
→ By using the fact above
∴ PS bisects QR
∴ S is the midpoint of QR
→ That means S divided QR into 2 equal parts QS and SR
∵ QS = SR
∵ QS = 6n + 3
∵ SR = 4n + 11
→ Equate them to find n
∴ 6n + 3 = 4n + 11
→ Subtract 4 n from both sides
∵ 6n - 4n + 3 = 4n - 4n + 11
∴ 2n + 3 = 11
→ Subtract 3 from both sides
∵ 2n + 3 - 3 = 11 - 3
∴ 2n = 8
→ Divide both sides by 2
∴ n = 4
→ Find the length of QS by substitute x in its expression by 4
∵ QS = 6(4) + 3 = 24 + 3
∴ QS = 27
∵ QS = SR
∴ SR = 27
∵ QR = QS + SR
∴ QR = 27 + 27
∴ QR = 54 units
∴ The distance of QR is 54 units
How do I find a table that represents Y as a function of X
Answer:
C: x: 5, 2, 6, 4, 1, 3; y: 2, 2, 2, 2, 2, 2
Step-by-step explanation:
Things that can represent a function of x has to be able to be shown in the form of a function, such as "y =" or "f(x) =". I'm guessing you're learning about linear lines, so I'm going to talk about this with linear lines.
A linear line must be straight and for y to be represented as a function of x, it has to have a constant increase or decrease for every x. Here is how to identify non-function lines:
- If there are different y values for the same x value
- If the points in order do not create a straight line
- If the points in order do not have a repeating pattern
To identify a function, look for:
- Straight lines
- An actual written function (such as "y =" or "f(x) =")
- A pattern on a table
Now, the pattern you're going to be looking for on a linear table is an addition or subtraction one for every x. If the x values are in order, then for every 1 x, there should be a constant addition or subtraction to the y.
Here's an example of a table that represents y as a function of x:
- X: 1 2 3 4 5
- Y: 3 5 7 9 11
- Pattern: +2 y for every x with constant 1
- X: 3 1 5 4 7
- Y: 9 3 15 12 21
- Pattern: +3 y for every x with constant 0
Here's an example of a table that doesn't represent y as a function of x:
- X: 1 2 3 4 5
- Y: 2 5 8 2 4
- Pattern: None
- X: 3 1 5 1 7
- Y: 1 7 8 9 4
- Pattern: None

Answer:

Step-by-step explanation:

Answer:
12
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 8 on the left side and the dividend 96 on the right side like this:
8 ⟌ 9 6
Step 2:
The divisor (8) goes into the first digit of the dividend (9), 1 time(s). Therefore, put 1 on top:
1
8 ⟌ 9 6
Step 3:
Multiply the divisor by the result in the previous step (8 x 1 = 8) and write that answer below the dividend.
1
8 ⟌ 9 6
8
Step 4:
Subtract the result in the previous step from the first digit of the dividend (9 - 8 = 1) and write the answer below.
1
8 ⟌ 9 6
- 8
1
Step 5:
Move down the 2nd digit of the dividend (6) like this:
1
8 ⟌ 9 6
- 8
1 6
Step 6:
The divisor (8) goes into the bottom number (16), 2 time(s). Therefore, put 2 on top:
1 2
8 ⟌ 9 6
- 8
1 6
Step 7:
Multiply the divisor by the result in the previousy step (8 x 2 = 16) and write that answer at the bottom:
1 2
8 ⟌ 9 6
- 8
1 6
1 6
Step 8:
Subtract the result in the previous step from the number written above it. (16 - 16 = 0) and write the answer at the bottom.
1 2
8 ⟌ 9 6
- 8
1 6
- 1 6
0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 96 divided by 8 calculated using Long Division is:
12
0 Remainder

Solve the system using substitution. show work.
x=y−6
y=6−3x
Answer:
y=6
x=0
Step-by-step explanation:
X=(y-6)
y=(6-3x)
So For Y
y=6-3(y-6)
y=6-3y+18
add three so it would be 4y=6+18 which then equal 4y=24 then divide 4 then you'll have 6
and for X just plug in whats in (y)
x=(6-3x)-6
So again add 3x to both side to get 4x=6-6 which equal 0 then answer is 4x=0 divide 4 get 0
Find the volume for 3 different spheres by randomly choosing different radii.
Using the same radii values, find the volume of 3 cylinders where the height of the cylinder is the same as the diameter of the sphere.
(who ever does it I will give brainliest and answer 3 of there questions)
Answer:
Hii!!
Volume Of Sphere =[tex] \frac{4}{3} * π * r^3. [/tex]
Let r be 1cm, 3 cm, 6 cm.
So,
Volume of sphere 1 = [tex] \frac{4}{3} * 3.14 * 1^3. [/tex]
Volume of sphere 1 = 4.19 cm^3
Volume of sphere 2 = [tex] \frac{4}{3} * 3.14 * 3^3. [/tex]
Volume of sphere 2 = 113.04cm^3
Volume of sphere 3 = [tex] \frac{4}{3} * 3.14 * 6^3. [/tex]
Volume of sphere 3 = 904.32 cm^3
Volume of cylinders = [tex] π * r^2 * h. [/tex]
Let r be 1cm, 3 cm, 6 cm and h be 2cm, 6cm and 12cm respectively.
So,
Volume of cylinder 1 = [tex] π * 1^2 * 2. [/tex]
Volume of cylinder 1 = 6.28 cm^3
Volume of cylinder 1 = [tex] π * 3^2 * 6. [/tex]
Volume of cylinder 1 = 169.56 cm^3
Volume of cylinder 1 = [tex] π * 6^2 * 12. [/tex]
Volume of cylinder 1 = 1356.48 cm^3

We can write the volume of spheres with three different radii as given below
[tex]\rm Let\; R_1 , R_2, R_3 \; be \; the \; three\; radii\; of \; sphere \; respectively \\\\\rm Volume \; of \; first \; sphere = (4/3) \pi \ R_1^3 \\\\\rm Volume \; of \; second \; sphere = (4/3) \pi \ R_2^3 \\\\Volume \; of \; third \; sphere = (4/3) \pi \ R_3^3[/tex]
Also we can write the the volume of the cylinders as follows
[tex]\rm Volume \; of \; first \; cylinder = \pi R_1 ^2H_1 = \pi R_1^2 (2R_1) = 2 \pi R_1^3[/tex]
[tex]\rm Volume \; of \; second\; cylinder = \pi R_2^2H_2 = \pi R_2^2 (2R_2) = 2 \pi R_2^3[/tex]
[tex]\rm Volume \; of \; third \; cylinder = \pi R_3 ^2H_3 = \pi R_3^2 (2R_3) = 2 \pi R_3^3[/tex]
Volume of a sphere with radius R is given by equation
[tex]\rm Volume \; of \; the \; sphere \; of\; radius\; R = \bold{4/3 \pi R^3 }[/tex]
[tex]\rm Let\; R_1 , R_2, R_3 \; be \; the \; three\; radii\; of \; sphere \; respectively \\\\\rm Volume \; of \; first \; sphere = (4/3) \pi \ R_1^3 ........(1) \\\\\rm Volume \; of \; second \; sphere = (4/3) \pi \ R_2^3 .........(2) \\\\Volume \; of \; third \; sphere = (4/3) \pi \ R_3^3..........(3)[/tex]
Equation (1) (2) and (3) represent the volumes of three different spheres
Given that the heights of the cylinders are equal to the diameter of the spheres
so from this given condition we can write the following relations
[tex]\rm Height\; of \; first \; sphere = H_1 = 2R_1 \\\\ Height\; of \; second \; sphere = H_2 = 2R_2 \\\\Height\; of \; third \; sphere = H_3 = 2R_3 \\\\[/tex]
The volume of the cylinder is given by equation (4)
[tex]\rm Volume \; of \; the\; cylinder = \pi R^2 H........(4) \\\\Where R = Radius \; of \; the \; cylinder \\\\H \; is \; the \; Height \; of \; the\; cylinder\\[/tex]
From the given conditions of heights of cylinders and radius of the sphere.
We can write the the volume of the cylinders as follows
[tex]\rm Volume \; of \; first \; cylinder = \pi R_1 ^2H_1 = \pi R_1^2 (2R_1) = 2 \pi R_1^3[/tex]
[tex]\rm Volume \; of \; second\; cylinder = \pi R_2^2H_2 = \pi R_2^2 (2R_2) = 2 \pi R_2^3[/tex]
[tex]\rm Volume \; of \; third \; cylinder = \pi R_3 ^2H_3 = \pi R_3^2 (2R_3) = 2 \pi R_3^3[/tex]

Casey currently owes $500 to his parents. He plans to pay them $60 per month until it is
paid off. Sally also owes her parents money. She borrowed $600 from them and plans to
pay them back $80 per month. Is there a time when they will both owe their parents the
same amount of money?
Answer:
They will both owe their parents $200 when Casey is paying his 5th month and Sally is paying on her 5th month.
Step-by-step explanation:
If Casey pays 60 dollars after 5 months, he will have payed $300 dollars. He still needs to pay $200.(500-300) If Sally pays 80 dollars after 5 months, she will have payed $400 dollars. She still needs to pay $200. (600-400)

Sheila is taking medicine to help fight an infection. The function f(x) = 12(0. 82)^x models the amount of a 12-mg dose of antibiotic left in her bloodstream after x hours.
About how many mg are left in her bloodstream after 2 hours?
Given:
[tex]f(x)=12(0.82)^x[/tex]
where, f(x) is the amount of a 12-mg dose of antibiotic left in her bloodstream after x hours.
To find:
The remaining mg in her bloodstream after 2 hours.
Solution:
The amount of a 12-mg dose of antibiotic left in her bloodstream after x hours is represented by the function
[tex]f(x)=12(0.82)^x[/tex]
Putting x=2, we get the remaining mg in her bloodstream after 2 hours.
[tex]f(2)=12(0.82)^2[/tex]
[tex]f(2)=12(0.6724)[/tex]
[tex]f(2)=8.0688[/tex]
Therefore, the remaining mg in her bloodstream after 2 hours is 8.0688 mg.
