Answer:
y=-x +7 is the slope-intercept form and the graph is shown in the attachment.
Step-by-step explanation:
The given equation is

We solve for y to get:

This is now of the form, y=mx+c
This is called the slope-intercept form.
Since the slope is negative, the graph slopes backwards. Also the y-intercept is 7, so the graph will intersect the y-axis at 7
Answer:
Average salary: 56
Standard deviation of the salary: 8
Step-by-step explanation:
$56,000 dollars is 56 thousand dollars.
$8,000 is 8 thousand dollars.
The mean is the average. So the average, measured in thousands of dollars, is 56.
The standard deviation is $8,000. So, the standard deviation measured in thousands of dollars, is 8.

Answer:
b=7
Step-by-step explanation:
We want to determine the positive base b in which:

The easiest way to approach this is to convert all the numbers to base 10.


Next, we factorize the resulting expression.

The positive value of b for which the equality hold is 7.
