Answer:
- 14/9
- -3.6
- 5/4
- 11/2, 7/8, 5/18
Step-by-step explanation:
1. n = (11/6 -2/3)(4/3) = (7/6)(4/3) = 14/9
__
2. x = (9.82 -28.18)/5.1 = -3.6
__
3. y = 3/2 -1/4 = 5/4
__
4a. t = 2(3 -1/4) = 11/2
4b. y = (1/5 +1/2)(5/4) = ((2+5)/10)(5/4) = 7/8
4c. x = (11/3 -2)/6 = (5/3)(1/6) = 5/18
Answer:
f(x) = - 8
Explanation:
The given function is
f(x) =2x^2 -4x -6
The first step is to find the derivative of the function. Recall, if
y = ax^b
y' = abx^(b - 1)
Thus,
f'(x) = 4x - 4
We would equate f'(x) to zero and solve for x. We have
4x - 4 = 0
4x = 4
x = 4/4
x = 1
We would substitute x = 1 into the original function and solve for f(x) or y. It becomes
f(1) =2(1)^2 -4(1) - 6 = 2 - 4 - 6
f(1) = - 8
Thus, the minimum value is f(x) = - 8
I believe it would be 0.52
I think you have to do 120-60% and the answer is 48 dollars.
Answer:
Step-by-step explanation:
Given
Bisector: QS
Required
Determine PQR
Since PQR is bisected to PQS and RQS, we have that
Substitute expressions for PQS and RQS
Collect Like Terms
Divide both sides by 3
Solving for PQR;
Substitute 2 for x
