5 times 6.2 is your answer!!!:)
So in plain English it's saying if A Is an element of B, then A and B equals A or B. This is true sometimes
Answer:
The answer is
Step-by-step explanation:
f(x) & g(x) = f(x) + k
3•6 & 7•6 = 3•6 + k
18 + 42 = 18k
60 = 18k
Try deriving the equation you get to make sure your calculation is right.
y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em>
</em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y =
