If u have a solid dot, then there is an equal sign in the inequality....if it is shaded to the right, u use a greater then sign....if it is shaded to the left, u use a less then sign
3. solid dot on -1, shaded to the right......x > = -1
4. solid dot on 5, shaded to the left.....x < = 5
Answer:
Step-by-step explanation:
lower left triangle: 5^2 + x^2 = 13^2
x^2 = 144 => x = 12
So, area of triangle is : (5 * (12-4))*0.5 => 20
Shaded area: (8 *12) -20 => 96 -20
