Answer:
Solve for y by cross multiplying
So the Answer is y = 15
Step-by-step explanation:
If you want i can explain with more detail.
The total number of hours on stand by is 12 x 3 x 7 = 252 hrs.
The energy used would be (252 x 8.8)/1000 = 2.22 kW-hours.
Use a calculator or do it on paper
Answer:
y=0.5x
Step-by-step explanation:
y=mx+b
y2-y1/x2-x1
plug in the numbers and you'll have your answer
Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!
