Answer:
18
Step-by-step explanation:
b/2-5=4 ADD 5 TO BOTH SIDES
+5 +5
b/2=9
b/2=9/1 CROSS MULTIPLY
b=18
From this sequence we can see that it is betting larger by 5 every single time.
So we can infer that the n = 5.
But we also have to add a number after that because right now the sequence would be 5,10,15,20. We need to find out how we get to 2 from 5n.*
*2 is the first number in the sequence
And to get 2 from 5 you simply subtract the number 5 by 3. So you end up with 5n - 3
Now that you have the nth term just substitute the term you want to find out so in this instance it is 40. 40 * 5 = 200 and then you take away 3 so It the answer must be 197. Hope this helps
Answer:
7y^2 +8xy -3
Step-by-step explanation:
Distribute the minus sign and combine like terms.
= 7y^2 +6xy +2xy -3
= 7y^2 +8xy -3
We have been given amount of money in bank account vs. # of years in the question:
- 1 year: 500
- 2 years: 1,000
- 4 years: 1,500
- 8 years: 2,000
- 16 years: 2,500
Plotting these numbers on a chart, with x-axis representing the number of years and y-axis representing the amount of money in the bank account, we can see that the lines joining these points do not form a straight line, but form a curve. Hence, these numbers do not represent a linear function.
