Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: 
Then, solve:

a = -2
So yes, they're on the graph.
Hope this helped! :)
Answer:
Step-by-step explanation:
1-x²≥0
1≥x²
or x²≤ 1
-1≤x≤1
[if x²≤a,then -a ≤x≤a]
700<=560+0.08x
x is total sales $
the 560 is the constant weekly pay, since we're only calculating for one week.
we're adding 0.08x to account for the 8% of the total sales
solve it for x:
700-560 <= 0.08x
140 <= 0.08x
1750 <= x
or x >= 1750
meaning she needs $1750 worth of sales that week to earn atleast $700
as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
Answer:
2 gram/milliliter or 2000 kilogram/cubic meter
