c. they earn the same. If you divide Carl's hours by the amount of time he works, for instance, 45÷3=15, you get 15 for all of them. They earn the same.
Answer:
x = 13/8
y = -45/8
Step-by-step explanation:
9x + y = 9
3x + 3y = -12
Divide the second equation by 3
x+y = -4
Multiply this by -1
-x -y = 4
Add this to the first equation to eliminate y
9x + y = 9
-x -y = 4
-----------------
8x +0 = 13
Divide by 8
8x/8 = 13/8
x = 13/8
Now find y
x+y = -4
13/8 +y = -4
Subtract 13/8 from each side
13/8 -13/8 +y = -4-13/8
y = -32/8 - 13/8
y = -45/8
The equation y = 3(1.12)^x will double after 6 years.
In order to find this, we need to test all of the numbers in the parenthesis to the 6th power and see which comes closest to 2. We know that after 0 years, each equation will simply have the value of the number outside of the parenthesis, so we need the number inside to be 2 in order to get it to double. The following are each number in the parenthesis raised to the 6th power.
1.50^6 = 11.39
1.17^6 = 2.57
1.06^6 = 1.42
1.12^6 = 1.97
Since the one with 1.12^6 is closest to 2, it is the one that nearly doubles after six years.
