Your answer should be <span>x>2</span>
Answer:
x=5
Explanation:
Begin to isolate x by adding 12 on both sides of the equation
5x=2x+15
Subtract
2x on both sides of the equation
3x=15
Isolate x by dividing both sides of the equation by
3x=5
Answer:
a

put f of x in to the x spot
Answer:
A(n) = 5.1×n + 4.5
Step-by-step explanation:
A(n) = A(n-1) + 5.1
A(1) = 9.6
A(n) - A(n-1) = 5.1 ,where n ≥ 1
This means that (A(n)) is an arithmetic sequence where :
<u>The common difference</u> r = 5.1
and
<u>The first term</u> A(1) = 9.6
Therefore
A(n) = A(1) + (n - 1)×r
= 9.6 + (n - 1)×5.1
= 9.6 + 5.1×n - 5.1
= 5.1×n + (9.6 - 5.1)
= 5.1×n + 4.5
