Answer:
k=2/3
Step-by-step explanation:
Step 1:
Step 1 in solving the exponential equations is re-writing the base same as other side of the equation
so,

Step 2:
Second step is equating the exponents
The rule used is:

So in this case

So the solution is:
k=2/3 ..

Answer:
2/3
Step-by-step explanation:
The slope of a line can be computed as:

where
is the increment along the y-direction
is the increment along the x-direction
We can choose the following two points to calculate the slope of the line shown:
(0,1) and (3,3)
Therefore, the slope of the line is

Two lines are said to be parallel if they have same slope: therefore, a line parallel to the one shown should also have slope of 2/3.
Answer:
36%
Step-by-step explanation:
20 % solution in 4/5 parts of the mmixture gives 80/5
100% solution in 1/5 parts of the mixture gives 100/5
total would give 80+100/5= 36% solution
