Well a root means that y will equal zero when x is that root number. we are given the roots. So when x = 1/2 or -1/3 then y = 0.
it has to be quadratic with an x^2 since it has 2 roots. So we will write basic formula
y = (x + a) (x + b)
in this basic quadratic the opposite of a and b will be roots. this means negative a and negative b are roots or -a and -b are roots.
so we can fill in our roots for a and b if we want but.remember we.have to use the opposite of.our roots because we.use -a and -b.
so let's fill in our opposite.roots for.a and.b
y = (x + (-1/2)) (x + (-(-1/3)))
since I have two negatives in front of the 1/3 it becomes positive.. So
y = (x - 1/2)(x + 1/3)
this is an equation with those roots. You can multiply it out if necessary.
y = x^2 - 1/6x - 1/6
I think that's what it comes out to.
Answer:
1506meters
Step-by-step explanation:
1hour-60minutes
which means half an hour is 30minutes,so it's more like they are asking you to find how far the swimmer can swim in 30minutes
50.2-1min
x -30min
x=50.2×30
x=1506meters
The correct answer is B)
Writing the sequence numerically, we have 4, 7, 10, ...
This is an arithmetic sequence, since there is a constant, 3, added each time. This gives us the explicit formula
Using the distributive property, we have
Combining like terms, we have
Answer: The answer is 715 minutes more.
Step-by-step explanation:
1500-785=715
Double check::::::::::::
715+785=1500
