Answer:
$6
Step-by-step explanation:
let x and y be the number of chip and pretzel bags respectively :
4x%2B2y%3 C=20
:
if x=1 then 4%281%29%2B2y%3C=20--->{{2y<=16}}}--->y%3C=8 :
if x=3 then 4%283%29%2B2y%3C=20--->{{2y<=8}}}--->y%3C=4 :
so chips 1 and pretzels 8 :
chips 3 and pretzels 4.

Find the discrimant.

This means there is one real solution. Since the discramnt equal 0.
There are 9 seniors.
Although there are several ways of solving this problem, I just did what was easiest for me in my head. I divided 36 by 4, which gave me 9.
Answer:
y = (-1)x
Step-by-step explanation:
What you are to do here is to "rewrite -y - x = 0 in the slope-intercept form y = mx + b."
Start by solving -y - x = 0 for y: -y = x or y = -x.
Rewrite this by inserting the coefficient 1 and representing b by 0:
y = (-1)x + 0
which is equivalent to y = (-1)x
