Answer:
y - x + z
Step-by-step explanation:A good way to tackle this problem is to check for the signs of all the variables. In your original expression, x-y+z, x and y are positive and y is negative.
We have :
p ( x ) = x² - 1 and q ( x ) = 5 ( x - 1 )
( p - q ) ( x ) = ( x² - 1 ) - 5 ( x - 1 )
Answer:
C ) ( x² - 1 ) - 5 ( x - 1 )
Hey hey!
So when a problem tells you that something equals something else, you substitute it with that. So if H = 1/3 then they want to know what 1/3 + 1/3 equals.
Let’s try it!
1/3+1/3 = 2/3
Your answer is 2/3 or... two thirds.
