6x - 3 > 4x + 5 |add 3 to both sides
6x > 4x + 8 |subtract 4x from both sides
2x > 8 |divide both sides by 2
x > 4 ⇒ x ∈ (4; ∞)
Answer:slope is -4
Step-by-step explanation:
1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C
4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F
5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104

Answer:
585°
Step-by-step explanation:
2
π = 360° = 180/pi
(13pi/4) x (180/pi)
(13/4) x (180/1)
(13/1) x (45/1)
585°
