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.

Which expression is equivalent to the product of p+7/3 and 6/p , where p is not equal to 0?

vichka [17]

Answer:

$\frac{(6p+14)}{p}$

Step-by-step explanation:

$(p+\frac{7}{3})(\frac{6}{p})$

Making denominator same in first bracket we get

$(\frac{3p+7}{3})(\frac{6}{p})$

$(\frac{(3p+7)*6}{3*p})$

Dividing 6 by 3 we get 2

$(\frac{(3p+7)*2}{p})$

using distributive law

$(\frac{6p+14}{p})\\$

Hence this is our answer

This last one I need help on too

ExtremeBDS [4]

Answer:

$x=\frac{3}{4}+i\frac{\sqrt{7}}{4},\:x=\frac{3}{4}-i\frac{\sqrt{7}}{4}$

Step-by-step explanation:

simplify $\frac{-3}{x-2}$ by putting the negative sign on the outside. $\frac{2x}{x-1}-\frac{2x-5}{x^2-3x+2}=-\frac{3}{x-2}$

find the LCM of the denominators. It is (x-1)(x-2). Multiply by the LCM:

$\frac{2x}{x-1}\left(x-1\right)\left(x-2\right)-\frac{2x-5}{x^2-3x+2}\left(x-1\right)\left(x-2\right)=-\frac{3}{x-2}\left(x-1\right)\left(x-2\right)$

Simplify:

$2x\left(x-2\right)-\left(2x-5\right)=-3\left(x-1\right)$

solve: $x=\frac{3}{4}+i\frac{\sqrt{7}}{4},\:x=\frac{3}{4}-i\frac{\sqrt{7}}{4}$
