If 11 - 3x = x, then 20x=

dimaraw [331]

Answer:

20x = 55

Step-by-step explanation:

First you have to add 3x to both sides of 11-3x=x

$11-3x=x\\+3x=+3x\\11=4x$

Now that you have 11 = 4x you divide 4 on both sides $\frac{11}{4} =\frac{4x}{4}$

11/4 = x

But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75

so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55

$20(\frac{11}{4})=55\\20(2.75)=55$

What is the inverse of the given relation?<br> y=3x+12

stich3 [128]

For this case we have the following function:

$y = 3x + 12$

We change the variables:

$x = 3y + 12$

From here, we clear the value of y.

$3y = x-12\\y = \frac {x} {3} -4$

Then, we make the following change:

$y = f (x) ^ {-1}$

Finally, the inverse function is:

$f (x) ^ {- 1} = \frac {x} {3} -4$

Answer:

The inverse of the given relation is:

$f (x) ^ {- 1} = \frac {x} {3} -4$

kifflom [539]

Answer:

$792\ \text{pounds}$

Step-by-step explanation:

$x_1=70$ cubic feet of fertilizer is used in $y_1=770$ pounds of strawberries

$x_2=90$ cubic feet of fertilizer is used in $y_2=990$ pounds of strawberries

$x=72$ cubic feet of fertilizer is used

Linear interpolation is applied

$y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}$

72 cubic feet of fertilizer will yield $792\ \text{pounds}$ of strawberries.

Which of the following is r2 + 4s evaluated for r = 4 and s = 1.5?

11Alexandr11 [23.1K]

So if you have r^2 + 4s and r=4 and s = 1.5 r^2 is 4^2 which is 16 and 4s is 1.5 x 4 which is 6 so you do 16 + 6 which is 22 so the correct answer is a.
