3. To solve the equation
7x + 5 = 3x – 7
first rewrite the equation as f(x) = g(x) where
6. Find the point of intersection of
f(x) = –5x + 1 and g(x) = –3x – 7
16. Solve the linear inequality graphically.
5x + 8 < –x – 4
20. Graph. f(x)=|x+3|-4
24. Solve the equation graphically.
| x | = 3
25. Solve the equation graphically.
| x – 1 | = 2x + 13
