F(x,y) =3x + 5y (hope this helps )
Answer:
f^-1(x) = (x-8)/4
Step-by-step explanation:
To find an inverse function, simply flip the x and y variables in a equation and then solve in terms of y.
x = 4y + 8
x - 8 = 4y
y = (x-8)/4
And we have our final answer!
Answer:
1/169
Step-by-step explanation:
There are 4 aces in a deck of 52.
The probability that the first card is an ace is 4/52.
Since the card is replaced, the probability that the second card is an ace is also 4/52.
The total probability is (4/52) (4/52) = 1/169.
Answer:
90 + x
Step-by-step explanation:
supplementary angles are angles that add up to 180.
90 + 90 = 180
-x + x = 0
90-x + 90 + x = 180.
so, your answer would be 90 + x
Check! lets say X = 6
90-6 + 90 + 6 = 180.
Good luck with your schoolwork/homework!

3(6/8−1/2)+0.25
Rewrite 6/8 and 1/2 to have common denominators:
1/2 = 4/8
Now you have
3(6/8−4/8)+0.25
Simplify inside the parenthesis first:
3(2/8) +0.25
2/8 reduces to 1/4"
3(1/4) +0.25
Multiply 3 and 1/4:
0.75 + 0.25
Now add to get the final answer, which is 1.00
