This should not be in the elementary school section I didn't even learn about this....
Answer:
-1
Step-by-step explanation:
-5-15+4+15
=-20+19
=-1
Step-by-step explanation:
The values of x would be 7, 8 or 9.
Solve for x then replace x with f⁻¹(x) and y with x
y=(4^x-5)/3
times 3
3y=(4^x-5)
add 5
3y+5=4^x
take log₄ both sides
log₄(3y+5)=x
switch
f⁻¹(x)=log₄(3y+5)
Answer:
= n - 7
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence
d = - 5 - (- 6) = - 4 - (- 5) = - 3 - (- 4) = 1
This indicates the sequence is arithmetic with nth term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 6 and d = 1 , then
= - 6 + 1 (n - 1) = - 6 + n - 1 = n - 7
