Answer:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no solutions. If it's equal to 0, there is one solution.
Step-by-step explanation:
x² - 14x + 46 = 0
subtract 46 from both-side
x² - 14x = -46
Add the square of the half of the co-efficient of x
x² - 14x + (-7)² = -46 + 7²
(x-7)² = -46 + 49
(x-7)² =3
Take the square root of both-side
x-7 = ±√3
x-7= ±1.732
Add 7 to both-side of the equation.
x= 7 ± 1.732
Eithe x= 7 + 1.732 or x= 7 - 1.732
x=8.732 or x=5.268
Therefore x = 8.732 , 5.268
Answer:
5 visits
Step-by-step explanation:
70 + 12.5 = 82.5 points
145 - 82.5 = 62.5
62.5 ÷ 12.5 = 5

Answer: 4th root of (1/x)^5
Step-by-step explanation: negative exponent makes the x become 1/x. The 4 goes to the outside of the radical, and the 5 stays as the exponent
