The correct answer is -7/8
I used a calculator
Write the decimal number as a fraction
(over 1)
3.1818 = 3.1818 / 1
Multiplying by 1 to eliminate 4 decimal places
we multiply top and bottom by 4 10's
Numerator (N)
N = 3.1818 × 10 × 10 × 10 × 10 = 31818
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 = 10000
N / D = 31818 / 10000
Simplifying your fraction
= 31818/10000
= 15909/5000
= 3 909/5000. Hope this helped!!!
Answer:
Step-by-step explanation:
-2x²=-8x+8 means : -2x²+8x-8
the discrinant of the quadratic equation is : delta = b²-4ac
when a=-2 and b=8 and c= -8
calculate delta = (8)²-4(-2)(-8) ......continu
Answer:
