If we have
y = 6x + 1 and x - y = 11, we can take advantage of y - y = 0 as follows:
Subtract x from both sides of the 2nd equation:
-y = 11 - x
Now combine
y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12. Solving for x, x = -12/5. Using the equation above, find y:
-y = 11 - x
= 11 - (-12/5)
= 55/5 + 12/5 = 67/5
Then the solution is (-12.5, 67/5).
Answer:
1/9
Step-by-step explanation:
The answer is 1/9 because we already know the only even number on the spinner is 8. We have a 1/3 chance on landing on 8. Then it says we have to land on 7. There is also a 1/3 chance for landing on 7. So from this information, we do (1/3)*(1/3)=1/9
3) Brett arrives 2 hours later than Lionel.
That is the correct answer.
(Sorry, I misinterprated the question before.)
Answer: 1
Step-by-step explanation:
Rewrite as (i^4)^6
Rewrite i^4 as 1
Rewrite i^4 as (i^2) ^2
((i^2)) ^2)6
Rewrite i^2 as -1
((-1) ^2) 6
Raise -1 to the power of 2
1^6
One to any power is 1.
