Step-by-step explanation:
The straight line passes through (0,1) and (2,-2).
Equation of a straight line passing through two points (x1,y1) and (x2,y2)
is given by:



Everything to the left of the line is shaded.
We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.
From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.
LHS=y=0
RHS=
LHS<RHS as 0<1
Hence , the inequality is:

Answer:
42 quarts
Step-by-step explanation:
I believe is your answer
Because u plug in -2 to all x
F(x)= (-2)^2-9(-2)+2
F(x)=4+18+2
F(x)=24
