For the inequality y+4x≤x2+2, where is the graph shaded and is the curve solid or dotted?

The graph shaded outside the parabola and the curve is solid.

Step-by-step explanation:

The given inequality is  

It can be rewritten as

The sign of inequality is , so the curve is a solid line.

The related equation of line is

Table of values is

x          0          2          4

y          2         -2          2

Plot these points and draw a U-shaped curve.

Check the equality for (0,0).

This statement is true. So, (0,0) lies in the shaded portion.

So, shade the graph outside the parabola.

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

the discriminant is 64 + 4*1*12 = 112

this is prime.
