1 yr = 12 months
4 yrs= 12x4 = 48 months
3/4 year= 3/4 x12 = 9
so 4 3/4 years= 48+9 =57 months
Answer:
the second one
Step-by-step explanation:
Y = -2x^2 + 4x + 3 Put brackets around the first 2 terms.
y = (-2x^2 + 4x) + 3 Take out a common factor of -2 from the brackets.
y = -2(x^2 - 2x) + 3 add a number inside the brackets that will make inside the brackets a perfect square. the method is shown below.
y = -2(x^2 - 2x + (2/2)^2 ) + 3
y = -2(x^2 - 2x + 1) + 3
y = -2(x^2 - 2d + 1) + 3 - (-2*1)
y = -2(x^2 - 2x + 1) + 3 + 2
y = -2(x - 1)^2 + 5
