Answer:

x = 1

Step-by-step explanation:

<u>Step 1:  Choose one of the equations to solve for y:</u>

x - y + 1 = 0

(-y) / -1 = (-1 - x) / -1

y = 1 + x

<u>Step 2:  Plug in y into either equation</u>

3x + 2(1 + x) = 7

3x + 2 + 2x - 2= 7 - 2

5x / 5 = 5 / 5

x = 1

Answer:  x = 1

kow [346]

Answer:

y ≤ 3x+1

Step-by-step explanation:

when the line is solid with no spaces in between, that automatically rules out A) and C). and the shading is underneath the line so that rules out B) as well. Also, if you look through the line that passes through the Y-axis, you can see that it is on +1 so that automatically tells you that both -1 are out.

Hope this helped you!

Tcecarenko [31]

Answer:

The repair/reboot time needs to be reduced by 600 hours so as to increase availability time by 5%.

Step-by-step explanation:

To increase availability by 5%, the amount of hours of availability is multiplied 105%.

therefore 1.05 × 12000 = 12600 hours

Therefore the repair/reboot time needs to be reduced by 600 hours.
