Answer:
A
Step-by-step explanation:
You would first subtract 6x from both sides which will give you something like:
-4= 2x - 9
then you would add 9 on both sides which would give you
5 = 2x
which now you would divide 2 by both sides with would give you
5/2 = x
simplify it one more time
2.5 = x
Here is the solution for finding mean mode and median
Answer:
D
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form using the method of completing the square.
Given
f(x) = 3x² - 24x + 10
We require the coefficient of the x² term to be 1 , thus factor out 3
3(x² - 8x) + 10
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
= 3(x² + 2(- 4)x + 16 - 16) + 10
= 3(x - 4)² + (3 × - 16) + 10
= 3(x - 4)² - 48 + 10
= 3(x - 4)² - 38, thus
f(x) = 3(x - 4)² - 38 ← in vertex form
Answer:
(4√11)/3
Step-by-step explanation:
16 + (-9) + 2 = 9 Well sixteen plus negative nine plus two is equaled out to be positive nine.
