Let C represent the cost in dollars and R represent the revenue in dollars. What is the break-even point? Use a table to help if

BigorU [14]

Answer:

$x = 5$

$R = C = 225$

Step-by-step explanation:

Given

$C = 15x + 150$

$R = 45x$

Required

The break even point

To do this, we make use of:

$R =C$

$45x=15x + 150$

Collect Like Terms

$45x-15x = 150$

$30x = 150$

$x = 5$

Substitute 5 for x in $R = 45x$

$R = 45 * 5$

$R = 225$

Hence, the break even point is:

$x = 5$

$R = C = 225$

Multiply and simplify: sq rt 7x ((sq rt x)-7sq rt. 7)

jarptica [38.1K]

7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x

Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______

BlackZzzverrR [31]

Answer:

Step-by-step explanation:

from the question that we have been given, we have to find out the next number after 36.

John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.

This can be seen below:

14 + 8 = 22

14 +22 =36

14 +36 =50

therefore the next sequence would be 50
