Answer:
- V(t) = 25(1.07^t)
- V(t) = 40(1.05^t)
Step-by-step explanation:
Put the given numbers into the given formula. It can be simplified a little bit.
Formula:
V(t) = P(1 + r)^t
<u>Coin A</u>
P = 25, r = .07
V(t) = 25(1.07^t)
<u>Coin B</u>
P = 40, r = 0.05
V(t) = 40(1.05^t)
Answer:
27 and 23
Step-by-step explanation:
We can solve this problem as a system of equations. X is the first number and Y is the second number.
The first equation is x+y = 50 and the second equation is x-y=4
Now we solve the system, using elimination method:
x+y=50
x-y=4
2x = 54
x = 54/2
x = 27
And from any of the equations we can find Y
27 + y = 50
y = 50 - 27
y = 23
Graph of Parallel lines shows a system of equations with no solutions
Step-by-step explanation:
Consider a set of equations
If we solve this both equations using any one of the solving method, (Substitution method) then we will get
substituting the following x in 2nd equation (21x + 6y = 24) We get
Put y= -2 in x equation
Comparing these (x,y) values we can understand that they never meet at a point
