Answer:
C) 8
Step-by-step explanation:
y=3*4-4
y=12-4
y=8
Vì tam giác ABC cân tại A (gt) mà AM là đg trung tuyến nên AM đồng thời là đg cao của t/giác đó:
AM là trung tuyến của t/giác ABC nên M là trung điểm BC:
=> BM =BC/2 =6:2=3(cm)
Xét tam giác AMB vuông tại M
AB^2 =AM^2+BM^2 ( theo định lý Py-ta -go)
Answer: 65 - $39 = $26 >> amount you save
26 / 65 = 0.4 = 40% >> discount rate
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 280 × 100 = 28000, 28000 ÷ 1400 = 20
- So, 20% were satisfied with their car
I hope this helps!
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
