Answer:
Step-by-step explanation:
there are function that "invert" each other..
subtraction inverts addition...
3+2 = 5 ... 5-2 = 3
division inverts multiplication
5*2 = 10 ... 10/2 = 5
Using that concept, "factoring" is basically the inverse of multiplication
3x^2 + 9x can be factored to 3x(x+3)
if you multiply that out it reverts back to the original equation
so x^2 + 5x + 6 factors to (x+3)(x+2)
if you multiply that out (foil it)
you get x^2 + 5x + 6
To solve for y, you do not get a value as there are no values in the equation. You can however still solve, as long as you make the equation "y =". To do this, you need to get y by itself, and we can see that it is being multiplied by r. To move the r onto the other side, we therefore have to divide by r on both sides. This leaves us with y = Z/r, which is your answer.
I hope this helps!
