The wording "earns 8% interest each year" does not make it clear whether the savings account interest is compounded. (It usually is in real life, but not always in math problems.) The graphical solution shows both simple interest and interest compounded annually.
Simple interest: the balances will both be $2941.18 after 5.88 years.
Compound interest: the balances will both be $3111.06 after 5.74 years.
This is known as The Theorem of Pythagoras
Basically is A2+B2+C2
Plug in the numbers as
16^2+B^2=30^2
Subtract 16 from both sides
16-16=0
30-16=14

Answer:
The solution of the given system of equations is (-6.667,7.667).
Step-by-step explanation:
The given equations are
...(1)
....(2)
put x=0 to find the y-intercept.
Therefore y-intercept of equation (1) is (0,1).
Therefore y-intercept of equation (2) is (0,-19).
put y=0 to find the y-intercept.
Therefore x-intercept of equation (1) is (1,0).
put y=0 to find the y-intercept.
Therefore x-intercept of equation (1) is (-4.75,0).
Draw the graph of both lines by joining their x and y-intercept.
From the graph it is noticed that both the line intersect each other at (-6.667,7.667).
Therefore solution of the given system of equations is (-6.667,7.667).
I think it's 10 times bigger than 756 because in 37,856 the 7 is in the thousands place and in 756 the 7 is in the hundreds place
