Solve the following inequality using both the graphical and algebraic approach:
1 answer:
x ≥ 8
Step-by-step explanation:
Given the inequality as;
8-x≥5(8-x)
Solving using the algebraic approach
8-x≥5(8-x) ----open brackets
8-x ≥ 40 -5x -----collect like terms
-x+5x ≥ 40-8
4x ≥ 32 ------divide both sides by 4
x ≥ 8

Answer:
w = -20
Step-by-step explanation:
- + 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
- = 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20
