Answer:
3xyz
Step-by-step explanation:
The required sum = 7xyz+(−5xyz)+9xyz+(−8xyz)
=7xyz–5xyz+9xyz–8xyz
=(7–5+9–8)xyz
=(16–13)xyz
=3xyz
To find graph this, you need to understand the equation.
The formula is y=mx+b, m being slope and b being y-intercept.
We start out graphing by finding where the y-intercept is--and we see that our intercept is 2. Place a point on (0, 2).
Now, we need to add our slope. Start at (0, 2) and go up 4 units. Next go to the LEFT (we have a negative slope, remember?). Continue this pattern.
It should look like this once it's done:
Answer:
36 students speak both english and french
14 students speak only english
B it is linear Bc it increases constantly. There is a constant slope that doesn’t change
