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
Answer:
The statement is True!
Step-by-step explanation:
Clare paid full price for an item.
Let Price of the item = x
Han bought the same item for 80% of the full price.
Han bought it for 0.8x
Clare said, I cants believe I paid 125% of what you paid, Han!
The above statement is True if;
125% of 0.8x = x
1.25 * 0.8x = x
x =x
The statement is True!
