Area of a rectangle= lxw
1.7=3.4z
1.7/3.4= 0.5
z=0.5
Answer:
answer is a
the height of the water increases 2 inches per minute
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:
0 solutions
Step-by-step explanation:
These system of equations are inconsistent (parallel to each other) which means that there are no solutions to this system.
