Answer:
f'(x) = 
Step-by-step explanation:
i) f(x) = 9 / x
ii) f'(x) = 

Answer:
6 centimeters
Step-by-step explanation:
Square E'F'G'H' is just square EFGH translated to the left.
It is still the same size, just in a different location.
Line segment EF is the same length as segment E'F'.
6 centimeters
This can be written as:
9-x>10
-x>1 (subtract 9 from both sides)
x<-1 (divide both sides by -1 and change the inequality sign)
Hope this helps
Yes it is a function. It is a horizontal line.
Every point on this line is of the form (x,4) where x can be any number you want. The y coordinate is fixed at 4 and cannot change. Two points on this line are (0,4) and (1,4). The horizontal line goes through 4 on the vertical y axis.
Why is it a function? Because it is impossible to draw a vertical line through more than one point on the graph of y = 4. The graph passes the vertical line test. Put another way, for any x input, there is exactly one y output.
Side Note: y = 4 is the same as y = 0x+4. Note how its in the form y = mx+b
m = 0 is the slope
b = 4 is the y intercept
Answer:
1x
Step-by-step explanation:
2x-3x[x-1]
=2x-3x+1
=-x+1
=0
