Answer:
Each property is mentioned with the corresponding expression.
Step-by-step explanation:
Writing the property in front of every expression:
1. Additive Identity: 11+0 = 11
2. Associative Property of Multiplication: x*(y*z) = (x*y)*z
3. Additive Identity: 8+(-8) = 0
4. Commutative property of Addition: 14+20=20+14
5. Multiplicative Inverse: 2*1/2 = 1
6. Multiplicative Identity : 22*1 = 22
7. Associative Property of Addition: (19+12)+8=19+(12+8)
8. Commutative Property of Multiplication: a*9=9*a
9. Distributive Property: 7(4+11) = 7(4)+7(11)
The ordered pair (10,63) is a solution to the inequality y < -0.2x² + 9x - 7. This illustrates that the statement is true.
<h3>What is an inequality?</h3>
It should be noted that an inequality simply means a statement of an order relationship between two numbers and algebraic expressions.
From the information given, the equation illustrated is:
y < -0.2x² + 9x - 7.
63 < 0.2(10)² + (9 × 10) - 7
63 < 20 + 90 - 7.
63 < 103
In this case, the ordered pair (10,63) is a solution to the inequality y < -0.2x² + 9x - 7. This illustrates that the statement is true since sixty there is less than one hundred and three.
Therefore, this is true.

Step-by-step explanation:
A graphing calculator can show you the graph right away. Or you can plot it by hand.
Since both inequalities do <em>not</em> include the "or equal to" case, the lines they represent (y=-x-1, y=x+4) will be dotted lines.
Of course, you can read the y-intercept from the equation. (It is the constant, the value of y when x=0.) The slope is the coefficient of x, so is -1 for the line with the negative y-intercept, and +1 for the line with the positive y-intercept.
The solution to each inequality is shaded. For y < ( ), the shading is below the dotted line. For y > ( ), the shading is above the dotted line. Then the solution to both inequalities is the doubly-shaded area.
