Answer:
-3x+1
Step-by-step explanation:
0, I put y=(0-7)x into a graphing calculator
6 centilitre = 60 millilitre
Total liquid consumed = 355ml + 60ml = 415 mlillilitres
2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
