<em>*To solve an inequality, it's the same as solving an equation; isolate the variable to one side.</em>
For this, all you need to do is divide both sides by -4. And since we are dividing by a <u>negative</u>, flip the inequality sign and your inequality is 
Now to graph this. Since x can be "equal to" 1/4 ( ≤ = less than or equal to), you will have a <u>closed circle on 1/4.</u> And since x can also be "less than" 1/4, <u>the arrow will be going to the left of 1/4.</u>
Answer:
100°
Step-by-step explanation:
Supplementary means the sum of the angles is 180°
so we add 4+5 = 9
180/9 = 20
20 now we multiply according to the ratio
20x4:20x5
80:100
the measure of the largest is 100°
<span>Subtraction exhibit a property of closure over the set of real numbers because if you subtract two numbers from the real numbers set, the result will still be a real number.
Example:
Let RS be a set of real numbers.
RS = {1, 2, 3}
Suppose I get 3 and subtract 1, 3 - 1, the result is 2 which is a real number. We can try a non-commutative 1 - 3 and yet it will still give us a real number which is -2.
</span><span>Subtraction is non-commutative because if we interchange numbers in subtraction, the result will either be positive or negative.
Example:
3 - 1 = 2. The answer is 2; but we can not say this is true for 1 - 3 because it will yield -2.
