Response:
First, subtract one-half from each side of the equation.
Next, divide both sides by 6/7.
Then, multiply each side by 7/6.
Detailed explanation:
I simply took the question on ed.
Answer: x1 = 251/26, x2 = -111/26
Step-by-step explanation:
Greetings!
As illustrated in the diagram, the point you seek is where the two lines intersect.
This intersection point is found by solving the system of linear equations (both equations must be satisfied by the point):

You can approach solving it using the substitution method:

Then substitute x1 into equation 2 to resolve x2:

After which, utilize the x2 value to establish x1:

Answer:
This situation illustrates Extrapolation.
Step-by-step explanation:
Extrapolation involves predicting the future based on the premise that current or historical trends will persist.
This also entails assuming the methodologies employed to gauge past trends will apply in the future.
For instance, consider projections regarding global population.
In this case, the number of Elvis Presley impersonators has risen from 48 at his death in 1977 to 7,328 today. If we estimate that by 2016, one in four individuals will become an Elvis impersonator based on the growth trend, this exemplifies Extrapolation.

Answer:
A reasonable estimate for the constant of variation is 0.25 kWh daily.
Step-by-step explanation:
The problem provides us with the following:
- The graph shows electricity usage.
- The kilowatt-hour consumption of a clock radio directly correlates with the passage of days.
- The x-axis represents the number of days, while the y-axis indicates usage in kilowatt-hours.
- Some coordinates on the graph include: (0,0), (2,0.5), and (6,1.5)
Formula for the constant of variation:

By inserting values from the points (2,0.5) and (6,1.5), we arrive at:

As a result, the reasonable estimate for the constant of variation is 0.25 kWh per day.
