From this we know that x = -8
So all we need to do is plug -8 into the equation everywhere there is an x
So y = -4 * -8 + 3
y = 32 + 3
So y is equal to 35, and since y is the output, the output is 35
Some institutions use 360 days a year (because then they charge more interest than 365 days).
Assuming the 360 days a year rule, the the daily rate is
6.5% for a year, or 270/360*6.5% for 270 days.
The future amount is then
4000*(1+0.065*270/360)
=$4195 (simple interest).
Distributive property
2x^3 + 10x
The answer is x=6.
Hope this helps.
