The solution of the inequality is x > -5
<h3>How to solve inequality?</h3>
In equality are expression that contains <, >, ≤ and ≥.
Inequality are operator use for comparison.
Therefore,
-3x + 5 < 20
subtract 5 from both sides of the inequality
-3x + 5 < 20
-3x + 5 - 5 < 20 - 5
-3x < 15
divide both sides by -3
-3x < 15
-3x / -3 < 15 / -3
x > - 5
Therefore, x > -5

Answer:
x = - 9, x = 10
Step-by-step explanation:
Given
x² - x - 90 = 0
Consider the factors of the constant term (- 90) which sum to give the coefficient of the x- term (- 1)
The factors are - 10 and + 9, since
- 10 × 9 = - 90 and - 10 + 9 = - 1 , thus
(x - 10)(x + 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 10 = 0 ⇒ x = 10
x + 9 = 0 ⇒ x = - 9
lesser x = - 9
greater x = 10
