The first one is correct. I graphed it on desmos and it looks almost identical to the one in your picture.
Answer:
70
Step-by-step explanation:
Chem : Phy = 3: 2
Since we have 105 pupils studying Chem and let's say we have x students stuyding Phy.
We have :
x=70
Answer:
x1 = 5
x2 = -1
x3 = 3
x4 = 2
x5 = 1
Step-by-step explanation:
x1 + x2 − 2x3 + 3x4 + 2x5 = 6
3x1 + 3x2 − x3 + x4 + x5 = 12
2x1 + 2x2 − x3 + x4 − 2x5 = 5
4x1 + 4x2 + x3 +0x4 − 3x5 = 16
8x1 + 5x2 − 2x3 − x4 + 2x5 = 29;
we apply the gauss jordan method
<span>y = (x + 2)(x - 3)
thats the equation you could use
