Answer:

Step-by-step explanation:
Because we are told equivalent expressions for y and z we can plug those in to 2(y+z).

Then simplify by combining like terms of the expressions. Values ending in x^2 can be combined with each other.

Now we can distribute the 2 by multiplying each value in the parentheses by 2.

What you have to do is subtract 3 2/15 from 7 5/9. You can also use decimals but that doesn't work all the time since the are infinite numbers (you will see what I mean later on) So what you can do is find the improper fraction of each one, and subtract it from each other. It would be 68/9 - 47/15, which would give you a total of 4 19/45. YOU'RE WELCOME :)

Step-by-step explanation:
( x − 2 ) 2 − 16 Set y equal to the new right side. y = ( x − 2 ) 2 − 16 Use the vertex form, y = a ( x − h ) 2 + k , to determine the values of a , h , and k . a = 1 h = 2 k = − 16 Find the vertex ( h , k ) . ( 2 , − 16 )
