After you get the equations: 3x + 4y =40 and 5x + 2y =34, use matrices and plug it into the graphing calculator which will give you the answers for x and y.
<span>X is going equal to 4 </span>
<span>and y is going to equal 7 </span>
<span>check: </span>
<span>3(4) + 4(7)= 40 </span>
<span>5(4) + 2(7)= 34
btw... never knew this is college level mathematics ^_^</span>
Answer:
y=14
Step-by-step explanation:
solve for y by simplifying both sides of the equation then insolating the variable
There's simple interest and there's also compound interest.
the difference is that, with simple interest, what you earn is a percentage of the "original amount you deposited", so if you deposited say 1000 and you earn 10% APR, you only get 100 bucks a year, 1st, 2nd, 3rd 20th year, no matter what year it may be, is always 10% of that original 1000.
so, in short, if you earned 75 bucks in the first year, well, for simple interest, that won't change for any subsequent year.
Answer:
Step-by-step explanation:
u2-u1=5.1-3.8=1.3
d=1.3
for that u need to plass 1.3 with all the numbers
7,7 + 1,3=9
9+1.3=10.3
10.3+1.3= 11.6
