Plug in y=x-4 to 2x+2(x-4)=16
You get 2x+2x-8=16, 4x-8=16, 4x=24, x= 6
The figure shows the growth rate of a certain bacteria in a lab, where the number of bacteria depends on the number of hours since the start of the experiment.
Now we have to find the number of bacteria after 16 hours.
From the graph , the graph seems to rise in y direction in the mid way between 10 and 20 .
The y coordinate in the mid way between 10 and 20 is approximately 80.
So we can say that the number of bacteria after 16 hours is 80.
Answer : last option that is 80 bacteria.
Answer:
The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts
Parallel lines are lines that do not meet in a xy-plane
If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.
Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.
Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.
