1.2 = k/4
multiply both sides by 4,
1.2*4 = k
k = 4.8

Step-by-step explanation:
It is given that Nolan began a savings account three years ago and the value of his account after x years is

Anias started an account today and the value of her account is

We have to find the amount of money that would she have had to invest to have the same amount of money she has now.
Let the required amount be P.
If Anias started saving x amount in the savings account three years ago, then today the value of her account is

The current value is 100.

Divide both sides by 0.0612.



Therefore the required amount is $94.23.
Answer:
2
Step-by-step explanation:
Let x = number of items Steve sells
Let y = salary earned
Create two equations:
Vacuum sales: y = 500 + 100x
Encyclopedia sales: y = 300 + 200x
Equal the equations and solve for x to find the number of items Steve needs to sell for the two salaries to be the same:
500 + 100x = 300 + 200x
Subtract 300 from both sides: 200 + 100x = 200x
Subtract 100x from both sides: 200 = 100x
Divide both sides by 100: 2 = x
Therefore, Steve would have to sell 2 items for the two salaries to be the same.
Answer:
Step-by-step explanation:
v(x)=12-2x-5
v(-2)=12-2(-2)-5
=11
v(0)=12-2(0)-5
=7
v(5)=12-2(5)-5
=-3
