Answer:

if f(x) = ax + b then f-1(x) = (x - b)/a

Step-by-step explanation:

Now

f(x)=ax + b

then y = ax + b

interchanging x and y , we get

or, x = ay + b

or, x - b = ay

or, (x - b)/a = y

therefore,f-1(x) = (x - b)/a

Korolek [52]

Answer:

−5+11i

Step-by-step explanation:

(3+6i)−(8−5i)

Subtract 8−5i from 3+6i by subtracting the corresponding real and imaginary parts.

3−8+(6−(−5))i

Subtract 8 from 3. Subtract −5 from 6.

The values in a dataset are 3.5, 2.5, 2.5, 3.5, and 3.0. If Xbar (sample mean) = sigma X / n, what is the mean for the sample?

RideAnS [48]

Answer:

$\bar x = 3.0$

Step-by-step explanation:

Given

$x: 3.5, 2.5, 2.5, 3.5, 3.0$

Required

The sample mean

This is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}$

$\bar x = \frac{15.0}{5}$

$\bar x = 3.0$

Theodore needs to mix a 10% fungicide solution with a 50% fungicide solution to create 100 milliliters of a 26% solution. How ma

solmaris [256]

Answer:

Therefore 40 milliliter of 50% fungicide solution is required

Therfore 60 milliliter of 10% fungicide solution is required

Step-by-step explanation:

i) Let the 10% fungicide solution have x milliliter and the 50% fungicide solution have y milliliter.

ii) Therefore 10x + 50y = 26(x + y)

x + y = 100

iii) form the first equation in ii) we get

16 x = 24 y Therefore $x = \frac{24}{16} y = \frac{3}{2} y$

iv) substituting the value obtained in iii) in the second equation in ii) we get

$\frac{3}{2} y + y = \frac{5}{2} y = 100$

Therefore y = 100 ÷ 2.5 = 40 milliliter

Therfore x = 100 - 40 = 60 milliliter
