Answer:
0.9x
Step-by-step explanation:
you just subtract the two
The tens digit is 8 more than the ones digit. There isn't any zeros.
The maximum digit is 9 because 10 would be 2 digits, 1 and 0.
So say the tens digits is 9.
9 _
The ones digit is 8 less so 9-8 = 1
9 1
There isn't any zeros which is correct.
The answer is 91.
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=

(divided both sides by -3z)
z=
Answer: First Option
a) exponential function going through point (0, 2) and ending up on the right
Step-by-step explanation:
Look at the attached image, the red line represents a function of the form:

Note that this function cuts to the axis and at the point (0, 1)
Also when x tends to ∞ f(x) tends to ∞ and when f(x) tends to -∞ then f(x) tends to zero.
If we perform the transformation
then the graph of y is equal to the graph of f(x) displaced 1 unit up. Then the new cutting point with the axis y will be: (0, 2) as shown in the attached image (blue line)
The transform function is 
Finally the answer is the first option
