x=-8

Step-by-step explanation:

7(x-2)+5x=-110

7x-14+5x=-110

12x-14=-110

12x=-110+14

12x=-96

x=-96/12

A software engineer has the capability of thinking 100 lines of code in five minutes and can type 100 lines of code in 10 minute
steposvetlana [31]

In one hour a software engineer will write 250 lines of code.

Given that, a software engineer has the capability of thinking 100 lines of code in five minutes and can type 100 lines of code in 10 minutes.

1st 5 minutes = He thinks the code

2nd 5 minutes = He writes the code

3rd 5 minutes =  Break

4th 5 minutes = Write [ because he can type up to 10 minutes if he thinks for 5 minutes ]

5th 5 minutes = Think [ He has completed 10 minutes of writing so he has to think ]

6th 5 minutes =  Break

7th 5 minutes = He writes the code

8th 5 minutes = He writes the code

9th 5 minutes = Break

10th 5 minutes = He thinks the code

11th 5 minutes = He writes the code

12th 5 minutes =  Rest [ he has completed his 10 minutes of working.

5 minutes thinking  + 5 minutes writing ]

Therefore, in one hour a software engineer will write 250 lines of code.

Find the slope of the line whose equation is 2x – 4y = 10.<br><br> How do I find the slope?
yulyashka [42]
To find the slope, u need to put the equation in y = mx + b form, where m will be ur slope.

2x - 4y = 10 ... subtract 2x from both sides
-4y = -2x + 10...divide both sides by -4
y = (-2/-4)x + (-10/4)
y = 1/2x - 5/2

y = mx + b
y = (1/2)x - 5/2
the slope(m) = 1/2
