Step-by-step explanation:
x²/(x²-9) + 1/(x-3) = 1/(4x-12)
4x² + 4(x+3) = 1
4x² + 4x + 11 = 0
Since the discriminant is negative, there are no real solutions.
Its because 20 is doubling its self. Its using 100% of its number, While 40 is decreasing by 50%. Half of forty is 20. Half equals 50%.
Answer:
The following are the answer to this question:
Step-by-step explanation:
In the question some data is missing, which is defined in the attached file please find it.
The table for point a:
plot for the Stem-and-leaf:
0 3 4 5 7 4
1 2 2 4 4 5 7 7 7
2 0 3 4 4 5 8 6
3 3 4 7 9 4
4 1
In point b:
Its distributed skewed is correct because in its points 1 is a tail on its right side.
please find the attached file.
if x = 3
3 > -1, and so you use the x² formula.
Plug in 3 for x
x² = (3)²
Simplify
3² = 3 x 3 = 9
9, or (A), is your answer
hope this helps
Answer:
z=44/3
Step-by-step
Subtract the numbers 52-12=40
3z-4=40
Add 4 to both sides
3z-4+4=40+4
SImplify
3z=44
Divide both sides by 3
3z/3 = 44/3
z=44/3 or decimal form= 14.66
