Mr. Kimball sells computer software. He earns a base salary of $41,250 and 8% commission on his sales. Write an equation to represent Mr. Kimball’s total pay p after selling d dollars of software.
Answer:
P=0.08d+41,250
Step-by-step explanation:
The total amount earned, p which is the sum of the base salary and the commision on sale can be expressed as ;
p = 41250 + 0.08dGiven the Parameters :
Base salary = 41250Commission percentage = 8% = 0.08Amount of sales made = dThe total pay after selling software worth $d can be expressed thus :
Base salary + (commission percentage × amount of sales)
Total pay = 41250 + (0.08 × d)
p = 41250 + 0.08d
Therefore, the total pay, p is expressed as 41250 + 0.08d

Answer: y = 2/3x - 9
We will use the point-slope equation to find the slope of this line
We know that according to the point-slope equation:
y = mx + b (where m is the slope and b is the y-intercept of the line)
Now, we will find the slope and the y-intercept of the line in order to find the equation of this line
Finding the Equation:Finding the Slope:We know that the formula for finding the slope of a line is:
Slope = Rise / Run
We will check the slope between the points, (-9,0) and (-6,2)
We know that rise = y2 - y1 (y of the second - y of the first coordinate)
Rise = 2 - 0 (replacing the values)
Rise = 2
We know that Run = x2 - x2 (x of the second - x of the first coordinate)
Run = -6 - (-9) (replacing the values)
Run = 3
Now that we know the values of Rise and Run, we can find the slope
Slope = Rise / Run
Slope = 2 / 3
Finding the Y-intercept:
We know that the y-intercept of a line is the y-coordinate of the point where the line intersects the y-axis
We can see in the graph that the line intersects the y-axis at the point (0,6)
the y-coordinate of the point (0,6) is 6
Therefore, the line has a y-intercept of 6
Equation of the Line:
We know that the general form for the slope-intercept formula is:
y = mx + b (where m is the slope and b is the y-intercept)
replacing the values of slope and y-intercept
y = (2/3)x + 6
Therefore, the equation of the line in the Graph is y = (2/3)x + 6

Recently, while digging in Chaco Canyon, New Mexico, archaeologists found corn pollen that was 4000 years old. This was evidence that Native Americans had been cultivating crops in the Southwest centuries earlier than scientists had thought.

(half-life of carbon-14 = 5730)
three less than the product of 5 and a number is equal to 2
To answer this question, write an equation to represent it. We will go part by part:
"Three less than" can be represented by -3
"The product of 5 and a number" can be represented by 5x
"Is equal to 2" can be represented by =2
The equation is: -3+5x=2
Now solve for x:
-3+5x=2
*add 3 to both sides*
5x=5
*divide both sides by 5*
x=1

If the graphs of the linear equations in a system are the same line, what does that mean about the possible solution or solutions of the system?
A. There is exactly one solution.
B. There is no solution.
C. There are infinitely many solutions.
D. The lines in a system cannot graph as the same line.
When the 2 graphs are the same. It'll be infinitely many solutions.
System Equations are to find the intercepts of graphs so just think that when 2 graphs are same, that means they both intercept each others infinitely.
So the answer is clearly C.

Which of the following shows the graph of y = –(2)x – 1?
Answer:
Graph B
Step-by-step explanation:
Hope I helped!
Graph given option B will be the answer.
This question is incomplete without the options, find the graphs attached.
Parent function for the given expression → [tex]y=2^x[/tex]
If the graph of [tex]y=2^x[/tex] is reflected across x-axis, the new function will be,
[tex]y=-2^x[/tex]
Further the inverted function is translated down by 1 unit on y-axis then the image function will be,
[tex]y=-2^x-1[/tex]
Hence, the graph given in option B will be the answer.

Using function concepts, it is found that the x-intercept of the exponential function is given at x = 3.
What are the x-intercepts of a function?They are the values of x for which y = 0. In a graph, they are the value of x at which the function crosses the x-axis.
In the graph given for the exponential function in this problem, it crosses the x-axis at x = 3, hence, the x-intercept of the exponential function is given at x = 3.
