For example 5/10\1/2 you would keep the 5/10 and flip the 1/2 to 2/1 and then multiply 5\10x2/1 to get 10/10 so 1

Answer:

Not a function

Step-by-step explanation:

If you use the line/ pencil test ***I think that's what it's called...

you put a pencil flat on the graph and if it touches more than one point, it is not a function. This only works with some graphs.But it works with this one.

If 2.5 is a root of the equation 2x^2+5x−q=0, what are the possible values of q?

bulgar [2K]

Answer:

q = -25 $10 +5 = \pm \sqrt{5^2-4*2*q} \\ 225 = 25-8q \\\\8q = -200 \rightarrow q = -\frac {200}8 = -25$

Step-by-step explanation:

Grab the generic solution of the equation. $\frac 52 = \frac{-5 \pm \sqrt{5^2-4*2*q}}{2*2}$ . Let's isolate the radical, and square both sides. $10 +5 = \pm \sqrt{5^2-4*2*q} \\ 225 = 25-8q \\\\8q = -200 \rightarrow q = -\frac {200}8 = -25$
