Taber invested money in an account where interest is compounded every year. He made no withdrawals or deposits.
The function A(t) = 525(1 + 0.05)t represents the amount of money in the account after t years.
The function is explained as below
Amount = Principal * ( 1 + interest rate ) ^ time
Principal is the amount that is invested in the beginning
Therefore, Taber originally invested $525
Answer:
A = 40x + 175
B = 50x + 125
5 hours
Step-by-step explanation:
The equations are as follows:
According to the question
Let us assume the number of hours be x
For company A
40x + 175
For company B
50x + 125
Now equate these two equations
40x + 175 = 50x + 125
175 - 125 = 10x
x = 5
Hence, the number of hours is 5
B as if you plug the co-ordinates into the equation and it equals 10: (3x4)-2= 12-2 =10
A doesn't work as the answer is 20
C doesn't work as the answer is 14
D doesn't work as the answer is -20
Answer:
39 touchdowns and 13 fieldgoals
Step-by-step explanation:
Let t= touchdowns
f = fieldgoals
They scored 35 times
t+f = 35
Touchdown is 7 pts and fieldgoal is 3 pt
7t+3f = 193
Multiply the first equation by-7
-7t -7f =-245
Add this to the second equation
-7t -7f =-245
7t+3f = 193
----------------------
-4f =-52
Divide by -4
-4f/-4 = -52/-4
f = 13
Now we can find t
t+f = 35
t+13 = 52
Subtract 13 from each side
t+13-13 =52-13
t =39
