120 percent=120/100=60/50=30/25=6/5, So it simplifies to 6/5.
The correct answer is 2x^3-40x-180
For a , C= 18.85
for b , C= 21.99
for 1 , C= 75.4
for 2 , C= 87.96
We can solve these equations by using substitution method where you substitute one equation to the other and solve for the value of the other variable. We do as follows:
y = 2x^2
y = –3x −1
2x^2 = –3x −1
2x^2 +3x +1 = 0
x1= -0.5
x2 = -1
y1 = 0.5
y2 = 2
