9x-12=3x show your work

Answers

Answer 1

Answer:

x=2

Step-by-step explanation:

given 9x-12=3x we want to solve for x

To do so we need to isolate the variable using inverse operations

to get rid of the 9x we subtract each side by 9x

9x - 9x  cancels out

3x - 9x =-6x

now we have

-12=-6x

now we want to get rid of the -6

to do so we divide each side by -6

-6x/-6=x

-12/-6=2

we're left with x=2

Answer 2

Answer:

9x=3x+12

9x-3x=12

9x-3x=12

6x=12

x=2

solution

x=2

The line cannot be formed by the intersection with plane and a cylinder.

What is intersection of cylinder and a plane?

A cylindric section is the intersection of a plane with a right circular cylinder.

Why line cannot be formed by the intersection with plane and a cylinder?

The intersection will be parallel lines if the plane is parallel to the cylinder's axis, it is impossible.

Because there are no intersecting lines on a cylinder, the intersection of a plane and a cylinder cannot create intersecting lines.

Hence, the option [tex]G[/tex] is correct answer.

I think the question is asking for the median. If that’s not right, let me know in the comments, and I will help you more.

If we write these data points in order:

2, 4, 4, 5, 5, 6, 6, 6, 6, 7, 8, 9, 10

I start crossing off numbers from one end to the other to find of the middle data point. That’s what the median is.

Remove the first 6 data points and the last 6 data points, and you have your median. If the next median problem you have to solve has an even number of data points, your average the middle two.

Given function is,

f(x) = [tex]\sqrt{x}[/tex]

If the given function is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] Or 1.5,

Transformed function will be,

h(x) = [tex]\frac{3}{2}[f(x)][/tex]

h(x) = [tex]\frac{3}{2}(\sqrt{x})[/tex]

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = [tex]\frac{3}{2}(\sqrt{x} )+1[/tex]

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] then shifted 1 unit upward.

Three girls share 12 000 in the ratio 2:3:7.Calculate how much each girl will get​

Answers

Answer:

1st girl- 2000

2nd girl- 3000

3rd girl- 7000

Step-by-step explanation:

1) add the ratio given: 2+3+7=12

2) the answer that you get is the whole and it is equal to the total: 12/12=12000

3) so now you'll simplify to get the share of each girl: 12/12=12000, what about 2/12(for the first girl)

12/12=12000, what about 3/12(for the 2nd girl)

12/12=12000, what about 7/12(for the 3rd girl)

4) after getting the answer for each, you can add their shares to see if they are equivalent to the total share

A Florida citrus grower estimates that if 150 orange trees are planted, each tree will produce 500 oranges. For each additional tree planted on the same acreage, the number of oranges each tree produces will decrease by 10 oranges. Find the maximum number of oranges the citrus grower can produce. How many trees will the citrus grower need to plant?

Answers

Answer:

The answer is below

Step-by-step explanation:

The question would not give a valid answer, the question should be in the form:

A Florida citrus grower estimates that if 30 orange trees are planted, each tree will produce 500 oranges. For each additional tree planted on the same acreage, the number of oranges each tree produces will decrease by 10 oranges. Find the maximum number of oranges the citrus grower can produce. How many trees will the citrus grower need to plant?

Solution:

Let x represent the number of orange trees above 30 to be planted on the acreage and let y be the number of oranges. Since for every additional tree there is a decrease of 10 oranges, hence:

y = (30 + x)(500 - 10x)

y = 15000 - 300x + 500x - 10x²

y = 15000 + 200x - 10x²

The number of oranges is maximum at y' = 0. Hence:

y' = 200 - 20x

200 - 20x = 0

20x = 200

x = 10

Second derivative test = y" = -20 (so this is maximal)

Therefore the number of trees needed = 30 + 10 = 40 trees

Maximum number of oranges = (30 + 10)(500 - 10(10)) = 40(400) = 16000 oranges

Survey: On free time 90 students like watching TV, 20 like watching TV but not reading, 80 like reading, 40 do not like watching TV. Question: Percent of total student like both watching televisan and reading

Answers

Answer:

 50 %

Step-by-step explanation:

From the diagram attached,

Percentage of total students that like watching television = [(WnR)/μ]×100......... Equation 1

The number of students that like watching television and reading (WnR) = 70

The total number of students (μ) = 40+20+70+10

The total number of students (μ) = 140

Substitute these values into equation 1

Percentage of total students that like watching television = (70/140)×100

Percentage of total students that like watching television = 1/2(100)

Percentage of total students that like watching television = 50 %

Im assuming you meant x² - 2x but correct me if i'm wrong!

so x is common in both terms so you can take it out and factorise it.
