There started with 50 and it doubles so that means:
100 at the end of year 1
200 at the end of year 2
400 at the end of year 3
800 at the end of year 4
15x-6
=3*(5x-2)
The final answer is 3*(5x-2).
Hope this helps~
Well, ok, the x intercepts aer where the function equals 0
also
if the x intercepts are r1 and r2 then the factored form of the function is
f(x)=a(x-r1)(x-r2) where a is a constant
well, we have it already in that form
f(x)=(x-3i)(x-3i)
the x intercept is at x=3i
standard form requires expansion
we expand to get
f(x)=x²-6i-9
Isolate the variable by dividing each side by factors that don't contain the variable.
y = 2 − x
Jeweler A: 125, 140, 155, 170, 185, 200
Jeweler B: 140, 152, 164, 176, 188, 200
If you count the hours it would be after 5 hours that they would be the same exact amount. The two jewelers would be paid $200.00 after 5 hours.
Sorry if I did anything wrong. Comment if I left something out or you don't understand.
