To solve 5/7 - 2/n = 1/21

Answer:

[tex]\huge\boxed{f^{-1}(x)=4x+48}[/tex]

Step-by-step explanation:

In order to find the inverse of a function, we need to follow a couple of steps.

We can follow these steps to find the inverse of this function.

Step 1: We can just replace the f(x) with y, making our function [tex]y=\frac{1}{4}x-12[/tex].

Step 2: We can swap where the x and y values are, making our equation

[tex]x = \frac{1}{4}y-12[/tex]

Step 3: We can now solve for y.

We now have the function as [tex]y = 4x+48[/tex].

Step 4: We can now replace the y with [tex]f^{-1}(x)[/tex].

[tex]f^{-1}(x) =4x+48[/tex]

Therefore the inverse of [tex]f(x) = \frac{1}{4}x-12[/tex] is [tex]f^{-1}(x) =4x+48[/tex].

Hope this helped!

Answer:

3x-8

Step-by-step explanation:

3x is three times the number, -8 is 8 less.

The estimate of the sum by rounding each number to the nearest tenth is 0.8

Estimation is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')

In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.

Rounding each number to the nearest tenth:

0.214 = 0.2

0.61 = 0.6

The sum = 0.2 + 0.6 = 0.8​

___

7×2 = 14

7×4 = 12

Answer:

9,000

Step-by-step explanation:

You would add it together.

6107 + 2960 = 9,067

You round the thousand (9) to the 0.

The rule is that if any number next to the one your rounding is higher then 5 or is 5 then the rounding number will go up, if its 4 or below if won't go up but stay the same.

9,067 would not go up but stay the same because of the rule.

Estimations are guesses from the mind so an exact answer wouldn't work but its whatever.

Answer:

bar graph??? we need a pic

The requried table that represents the bar graph is table H.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
The total number of students is 30,

Now,

10% of students take lunch,
So the number of students who take lunch,
= 10% of 30
= 3

Similarly,

Number of students who takes Breakfast = 9
Number of students who takes super = 18

Thus, the requried table that represents the bar graph is table H.

Answer:

Yen is the currency of Japan

Answer:

The slope of graph is [tex]\mathbf{\frac{3}{2}}[/tex]

Option C is correct option.

Step-by-step explanation:

We need to find the slope (rate of change) of the graph

The formula to calculate slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

Taking two points from the graph: (You can take any two points from the graph)

Point 1 (-4,-3)

Point 2 (-2,0)

We have: [tex]x_1=-4, y_1=-3, x_2=-2, y_2=0[/tex]

Putting values in the formula and finding slope

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-3)}{-2-(-4)} \\Slope=\frac{0+3}{-2+4} \\Slope=\frac{3}{2}[/tex]

So, the slope of graph is [tex]\mathbf{\frac{3}{2}}[/tex]

Option C is correct option.

Answer: 6 Containers are needed

Step-by-step explanation:

The ideal number of Kanban cards can be calculated using the following formula;

N = (DT × ( 1 + X)) / C

where N is total number of container,

D is panned usage rate of using work Centre

T is Average waiting time for replenishment of parts plus average production for a  container of parts,

X is policy variable set by management that reflects possible inefficiency in the system ,

C is capacity of standard container.

Now, given that;

D = 105 parts

T = 90min = 90/60 = 1.5 hrs

X = 0.35

C = 3 × 12parts = 36 parts

so; we substitute

N = (105×1.5 × ( 1 + 0.35)) / 36

N = 212.626 / 36

N = 5.9063 ≈ 6

Therefore 6 Containers are needed

Answer: 12 h + 135

Step-by-step explanation: 7h +135 + 5h = ?h + ?​

                                             7h +5h +135  

                                            =12h +135

So u combine like terms together  which are 7h and 5h which gives you 12 h.And then you have 135 left,so you add 12h to 135.

Ps.If you don't know what like terms are.I will explain down below.

Like terms are  variable that are the same.For an example 4y and 3y are like terms .Another example is 1/3 xy and 6xy .

The one that is shown has a negative b^2-4ac value.

We know this because the function has no real roots -> that means that they must be complex, which can only occur if b^2-4ac < 0

Answer:

[tex]H = 5200[/tex] - Hypotenuse

[tex]S_1 = 2000[/tex] - Leg 1

[tex]S_2 = 4800[/tex] - Leg 2

Step-by-step explanation:

Represent the dimensions as:

[tex]H = Hypotenuse[/tex]

[tex]Other\ Legs = \{S_1,S_2\}[/tex]

So, we have:

[tex]S_1 = 2000[/tex]

[tex]H = 400 + S_2[/tex]

Required

Determine the dimensions

Apply Pythagoras theorem

[tex]H^2 = S_1^2 + S_2^2[/tex]

This gives:

[tex](400 + S_2)^2 = 2000^2 + S_2^2[/tex]

Open bracket

[tex]160000 + 800S_2 + S_2^2 = 4000000 + S_2^2[/tex]

[tex]160000 + 800S_2 = 4000000[/tex]

Collect Like Terms

[tex]800S_2 = 4000000 - 160000[/tex]

[tex]800S_2 = 3840000[/tex]

Solve for S2

[tex]S_2 = \frac{3840000}{800}[/tex]

[tex]S_2 = 4800[/tex]

Recall that:

[tex]H = 400 + S_2[/tex]

[tex]H = 400 + 4800[/tex]

[tex]H = 5200[/tex]

Hence, the dimensions are:

[tex]H = 5200[/tex]

[tex]S_1 = 2000[/tex]

[tex]S_2 = 4800[/tex]
