Answer:
$20,285.51
Step-by-step explanation:
A = P + I where
P (principal) = $12,000.00
I (interest) = $8,285.51
A = Pe^(r*t)
A = 12,000.00(2.71828)^((0.075)*(7))
A = $20,285.51
e, also known as Euler's number, is a mathematical constant approximately equal to 2.71828
e here helps to show continously compounded interest

Answer:
261
Step-by-step explanation:
Answer:Yes it will remain the same
Step-by-step explanation:
because you are adding the same amount to both sides!
Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
Answer:
Step-by-step explanation:
hello :
the system is : y= 3x+4....(*)
y+6=3x....(**)
by (**) : y = 3x - 6
so : y= 3x+4
y= 3x - 6
means : 3x+4 = 3x - 6
4= -6.......(false)
conclusion : no reals solutions
