equation for first figure=2x+y=2
equation for second figure= 4x-y=8
(use formula x/a+y/b=1)
where, a=x component and b= y component..
Answer:
To find the average rate of change, we divide the change in the output value by the change in the input value. The Greek letter Δ (delta) signifies the change in a quantity; we read the ratio as “delta-y over delta-x” or “the change in y divided by the change in x”.
64/1×5/8=320/8. 320÷8=40. There is 40 gallons of gas in the truck
5^4 * 5^(-6) * 5
= 5^4 * 5^(-6) * 5^1
= 5^[ 4 + (-6) + 1 ]
= 5^[ 4 - 6 + 1 ]
= 5^(-1) <----- this is the answer.
I hope this helps. =)
