Answer:
f^-1(x) = cuberoot(x+5)
see image
Step-by-step explanation:
To find an inverse function:
first, write y in place of f(x)
second, switch the x and y.
third, solve for y.
last, replace y with inverse function notation, f^-1(x)
see image.
Answer:
$1,800
Step-by-step explanation:
If Mo pays 1/2 of the rent then he is paying 50%. Charlie is paying another 25%. This leaves the remaining 25% that Andy pays. Since Andy's payment amount is 450 then that means that 450 is equal to 25% of the total rent. Therefore, we simply need to multiply this amount by 4 to get the 100% of the overall rent.
450 * 4 = $1,800
Finally, we can see that the total rent amount is $1,800
Anyway
so the recursive rule tells the relationship between the previous term and the term we want to find
given
an=2n+11
it is clear that the first term is 13
2nd term is 15
3rd term is 17
each term increases by 2
so
a term is equal to the previous term plus 2
an=a(n-1)+2
the first one is the answer
Answer:
x = 18
Step-by-step explanation:
So since a || b,
7x + 11 = 10x - 43
3x = 54
x = 18
