Answer:
4/6
Step-by-step explanation:
→ Write the slope formula
(y₂ - y₁) ÷ (x₂ - x₁)
→ Substitute in the numbers
(3 - -1) ÷ (4 - -2)
→ Simplify
4/6
Answer:
- 9 < t < 5
Step-by-step explanation:
Isolate | t + 2 | by subtracting 4 from both sides
| t + 2 | < 7
Inequalities of the type | x | < a always have a solution of the form
- a < x < a, hence
- 7 < t + 2 < 7 ( subtract 2 from all 3 intervals )
- 9 < t < 5
Answer:
t=−3 or t=−12
Step-by-step explanation:
Step 1: Subtract -36 from both sides.
t2+15t−(−36)=−36−(−36)
t2+15t+36=0
Step 2: Factor left side of equation.
(t+3)(t+12)=0
Step 3: Set factors equal to 0.
t+3=0 or t+12=0
t=−3 or t=−12
