Which correctly describes how the graph of the inequality 4x - 2y > 20 is shaded?

Phantasy [73]

First we need to express y in this inequality:
-2y > -4x + 20
-y > -2x + 10
y < 2x - 10

The line isn't solid because the "less" sign doesn't include equal in it.
Because the sign is "less than" the shaded part is Below the line.

Merging these 2 conclusion we get the answer:
below the dashed line.

Grandma baked 969696 cookies and gave them to her grandchildren. One of the grandchildren, Cindy, received ccc fewer cookies tha

Angelina_Jolie [31]

The total number of cookies baked by grandma = 96

Number of grandchildren = 8

As given, all cookies were evenly divided among 8 children, let us assume that everyone except Cindy got equal share. So on being divided equally, it becomes, $\frac{96}{8}=12$ cookies per children.

But, as mentioned that Cindy received 'c' cookies less, so let us suppose Cindy received 'x' cookies.

Expression becomes: $x=12-c$

Hence, Cindy received 12-c cookies.
