Answer:
125
Step-by-step explanation:
So you can see that the sequence is all of the perfect cubes so knowing that the next perfect cube we have to find is 5's perfect cube which is 125.
Step-by-step explanation:
You have $7,000 in your savings account gaining 4% interest per year. If you don't replace the $800 in the savings account
<span>x+9=2x+1
Since both equations give the value of y, therefor y = y. You simply substitute y with its corresponding equation.
y = y
x + 9 = 2x + 1 *we need to find the value of x to get the value of y.
x - 2x = 1 - 9
-x = -8
-1x/-1 = -8/-1
x = 8
Substitute x with its value to get y.
Equation S: y = x + 9 </span>⇒ y = 8 + 9 ⇒ y = 17
Equation T: y = 2x + 1 ⇒ y = 2(8) + 1 ⇒ y = 16 + 1 ⇒ y = 17
<span>x+9=2x+1
</span>17 = 17
Answer:
= 
+ 2.5
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 2.5
The recursive formula allows any term in the sequence to be found by adding d to the previous term, thus
= + 2.5 ← recursive formula with a₁ = 3
