Yo sup??
y=3x+12
y-12=3x
x=y/3 - 4
f(y)=y/3 - 4
or
f(x)=x/3 - 4
where f(x) is the inverse of y.
Hope this helps
Answer:
Step-by-step explanation:
If you start with t1 = 8.6
and t2 = 6.4
Then tn - tn-1 = 6.4 - 8.6 = -2.4
In other words if you start at tn-1 and go to the next term tn you have to subtract 2.4 from the term to get to the next term.
t1 = 8.6
t2 = 6.2
t2 = 8.6 - 2.4 = 6.2
The difference is -2.4
In general tn+1 = tn - 2.4
Answer:
So the common difference is -2.4
Step-by-step explanation:
In an arithmetic sequence the common difference is the difference between any two consecutive terms
also formula for common difference is d= a(n) - a(n-1)
which means that if we have an arithmetic sequence i.e. a1,a2,a3 and a4
then their common difference will be
common difference = a₂-a₁= a₃-a₂ = a₄ -a₃
Now for the given sequence
Common difference = 6.2 - 8.6
= - 2.4
Check:
8.6 - 2.4 = 6.2
6.2 - 2.4 = 3.8
3.8 - 2.4 = 1.4
.
.
So the common difference is -2.4

Answer:
7
Step-by-step explanation:
3 = 3 X 2 + 1
2
= 6 + 1
2
= 7/2
therefore, the numerator is 7 which is the figure at the upper part of the improper fraction
Answer:
7 = ?
Step-by-step explanation:
3 1/2 is a mixed fraction
?/2 shows itself as an improper fraction
To have 3 1/2 turn into an improper fraction, you multiply the denominator(2) by the whole number(3)
3 x 2 = 6
With the remaining numerator, which is 1, you add it to the total product of 3 and 2, giving you 7
