Answer:
[-11/5,∞)
Step-by-step explanation:
1. Add 4 to both sides: 7x-4+4≥-15+2x+4
2. Simplify: 7x≥2x-11
3. Subtract 2x from both sides: 7x-2x≥2x-11-2x
4. Simplify: 5x≥-11
5. Divide both sides by 5: 5x/5≥-11/5
6. Simplify: -11/5
Answer:
25.5
Step-by-step explanation:
because you have to do 25×1.50 -12
Answer:
1
Step-by-step explanation:
sin²x = (sinx)²
cos²x = (cosx)²
Step 1: Define
sin²45° + cos²45°
Step 2: Rewrite
(sin45°)² + (cos45°)²
Step 3: Evaluate
sin45° = √2/2
cos45° = √2/2
(√2/2)² + (√2/2)²
1/2 + 1/2
