Answer:
infinite solutions
Step-by-step explanation:
4x=4x
Divide each side by x
4x/x = 4x/x
4 =4
This is always true,no matter what value we put in for x. So there are infinitely many solutions to the equation.
Answer:
A. 5
Step-by-step explanation:
The triangle will be a right triangle when the side lengths satisfy the Pythagorean theorem: the sum of the squares of the legs is equal to the square of the hypotenuse.
(x +1)^2 +x^2 = (√61)^2
x^2 +2x +1 +x^2 = 61 . . . eliminate parentheses
2x^2 +2x = 60 . . . . . . .subtract 1, collect terms
x^2 +x -30 = 0 . . . . . divide by 2, subtract 30
(x +6)(x -5) = 0 . . . . factor the quadratic
x = -6 or +5
The solution is x = 5.
_____
Side lengths cannot be negative. Solution values are values of x that make the factors zero. x+6=0 when x=-6, for example.
Answer:
Option B) 0.2143
Step-by-step explanation:
We are given the following in the question:
Numbers of exposures(x): 4,3,7
We have to find the maximum likelihood estimate of p.
Formula:

Putting the values, we get,

1. 3G
2. 15g
3. 15g
4. 6g+54
Answer:
Min: at x = 0, value = c
Max: at x = 0, value = c
Step-by-step explanation:
f(x) = ax² + c
Comparing to a(x - h)² + k,
h = 0, k = c
