Answer:
D
Step-by-step explanation:
128/2 = 64
The squareroot of 64 = 8
That means that only C or D could be true; 8 is in the numerator not the denominator.
Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.
There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.
Answer 8sqrt(y)/x
D
The independent variable in the relationship is the Number of Months and should be placed on the x-axis (the horizontal axis)
The dependent variable in the relationship is the Number of Fish and should be placed on the y-axis (the vertical axis)
Hope it helps.
Answer:
(r^2 - r - 1)(r^2 + r - 1).
Step-by-step explanation:
r^4 - 3r^2 + 1
We need to make this into a perfect square so the r^4 and the 1 fit the bill but not the -3r^2 so we have to correct for that.
A perfect square would be:
r^4 - 2r^2 + 1 ( = (r^2 - 1)^2 )
But we need -3r^2 so we add - r^2 at the end:
= (r^4 - 2r^2 + 1) - r^2 So now we have the difference of 2 squares and we write:
(r^2 - 1)^2 - r^2
= (r^2 - 1 - r)(r^2 - 1 + r)
= (r^2 - r - 1)(r^2 + r - 1)
The answer to your question is 11.
4x3=12-1=11
Let 1/x=the time it takes for person b to paint
let 1/22x the time that it takes for person a to paint
lastly we have the following since we know that when they work together that is how long it takes
to solve we first multiply both sides by 1694x
we then combine like terms
lastly we divide both sides by 22
