Answer:
13=x
Step-by-step explanation:
Side-spliting theorem
21/(x-4)=14/6
cross multiply
21*6=14*(x-4)
distribute 14
126=14x-56
add 56 to both sides
126+56=14x-56+56
leaving you with
182=14x
Divide both sides by 14 to get x by itself
182/14=14x/14
13=x
we can see that
the above curve is parabola
so, firstly , we can find vertex
vertex is (4,0)
now, we can use vertex formula of parabola
we can plug h and k
and we get
so, we can factor it as

Answer:
The copy machine makes 87.5 copies in one minute.
Step-by-step explanation:
Set up an equation to divide 4 into 350. This is because in order to know how many copies is being made in 1 minute, you need to determine the rate of copies per minute.
350 divided by 4 is 87.5.
Applying a dilation centered at the origin with scale factor 
has the effect of multiplying both coordinates of a point by :
So, in your case, the coordinates of the points double:
