Hey! This is a maximum because that's where it peaks. It doesn't go any higher from there so the coordinates are (0,-1) or A.
31.4% should be divided by 100 to get decimal
31.4/100
0.314
A scale of 1:50 000 means that every centimetre on the map is equal to 50 000 centimetres (500 metres) in reality.
The distance between two towns on that map is 6cm, therefore in reality there’s 6 * 50 000 = 300 000 centimetres, which is equal to 3 000 metres, which is equal to 3 kilometres.
Multiplying the 1st equation by -2:
-2x -8y = -16
2x - 5y = 29
13y = 13
y = 1
2x - 5 = 29
2x = 24
x = 12
I'm Pretty Sure It Would Be Answer A. {-6.6, -1.4}
