The value of x is x ≤ 9 for which y ≤ -5(x - 18) - 2 when y = 43.
<h3>What are inequalities and their types?</h3>
Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
The given inequality is y ≤ -5(x - 18) - 2.
Now the values of x when y = 43 is,
43 ≤ - 5(x - 18) - 2.
43 ≤ - 5x + 90 - 2.
43 - 88 ≤ - 5x.
- 45 ≤ - 5x.
5x ≤ 45.
x ≤ 9.

hello
so to find x, we need to use a rule.
the rule is: the exterior angle of a triangle is equal to the sum of the opposite interior angles.
so our exterior angle is xº, and the opposite interior angles are 53º and 45º.
we could set up a basic equation (although not completely necessary)
xº=53º+45º
xº=98º
hope this helps
have a nice day :)
