system of linear equation and compound inequality
November 16th, 2022
Please see attached file for full problem description.
Solve system by the substitution method.
1. y = 2x – 6
y = x – 5
2. 7x – 4y = 26
y = x – 5
————————————————————————————
Solve each system by the addition method. If there is no solution or an infinite number of solutions, so state.
3.6x + 2y = 8
2x – y = 6
4. 7x – 2y = 8
-14x + 4y = 8
————————————————————————————–
5. Solve the compound inequality. Give the graph or describe it.
x < 5 and x > 4
Solve each absolute value equation or inequality
6.|x – 5 | > -1
Solve the inequality:
7. 3 | 2x +3 | + 6 > 0
