Answer:
x=3 and y=4
Step-by-step explanation:
Let's solve your system by substitution.
x+y=7;x+2y=11
Step: Solvex+y=7for x:
x+y=7
x+y+−y=7+−y(Add -y to both sides)
x=−y+7
Step: Substitute−y+7forxinx+2y=11:
x+2y=11
−y+7+2y=11
y+7=11(Simplify both sides of the equation)
y+7+−7=11+−7(Add -7 to both sides)
y=4
Step: Substitute4foryinx=−y+7:
x=−y+7
x=−4+7
x=3(Simplify both sides of the equation)
Answer:
x=3 and y=4
PLS BRAINLIEST
C. 100 because 500 times 0.04(decimal form of 4%) is 20. 20 times 5(years) is 100
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.
Answer:
Last option
Step-by-step explanation:
I think it would be the last option because when you reflect over the x-axis, the x-axis switched signs.
So, -8 would be 8 , -7 would be 7, and 3 would be negative 3.
Dont think the y-axis value would change..
Hope this helps!
(If this was good..please give brainly.)
