What is an equation of the line that is parallel to the one shown and passes through (6, −5)?
A. y=−23x−1
B. y=32x−4
C. y=23x+1
D. y=−32x+4
Answer:
D is the answer
The equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Recall:
Slope of two lines that are parallel to each other will always be the same value.Slope = rise/runFrom the graph shown, the slope (m) of the line is [tex]-\frac{3}{2}[/tex].
Thus, the line that passes through (6, -5) and is parallel to the line in the graph will have the same slope of [tex]-\frac{3}{2}[/tex].
Write the equation in point-slope form by substituting (a, b) = (6, -5) and m = -3/2 into y - b = m(x - a).
Thus:[tex]y - (-5) = -\frac{3}{2} (x - 6)\\\\y +5 = -\frac{3}{2} (x - 6)[/tex]
Rewrite in point-slope form as y = mx + b
[tex]y +5 = -\frac{3}{2} (x - 6)\\\\y + 5 = -\frac{3}{2} x + 9\\\\y = -\frac{3}{2} x + 9 - 5\\\\\mathbf{y = -\frac{3}{2} x + 4}[/tex]
Therefore, the equation in slope-intercept form, of the line that passes through (6, -5) and is parallel to the line given is: D. [tex]\mathbf{y = -\frac{3}{2} x + 4}[/tex]Learn more here:

Hi there! :)
C. has both jump and infinite discontinuity.
Evaluate both piecewise functions at x = 1;
1 / (x + 1) = 1 / ((1) + 1) = 1/2
2x - 1 = 2(1) - 1 = 1
As the piecewise functions contain different y-values when evaluated at
x = 1, there is a jump discontinuity at x = 1.
However, the first function also contains a vertical asymptote or infinite discontinuity where it is undefined, or at x = -1. (1 / 0 = undefined). This means that the function also contains an infinite discontinuity.
Therefore, the correct choice is:
C. has both jump and infinite discontinuity.

Mr. Santos wanted to know the height of the tree. He observed from a point A that the angle of elevation of the top of the tree is 36 degrees. He then moved backwards 50 ft away from the initial point A, the angle of elevation of the top of the tree was 22 degrees. Find the height of the tree.
Answer:
The height of the tree is approximately 45.51 ft.
Step-by-step explanation:
The given information are;
The angle of elevation of the top of tree is 36 degrees
The distance backwards Mr. Santos moved = 50 ft.
The new angle of elevation of the top of the tree = 22 degrees
Therefore, we have;
The angle opposite to the 50 ft. side = 180 - (180 - 36) - 22° = 14°
Therefore, we have, by sine rule;
50/(sin(14)) = X/(sin(22))
X = (sin(22)) × 50/(sin(14)) ≈ 77.42 ft.
The height of the tree, T = X × sin(36°)
T = 77.42 ft. × sin(36°) ≈ 45.51 ft.
The height of the tree is approximately 45.51 ft

Which statement is true?
Answer:
B- For each hour that Michelle drove, she traveled an additional 50 miles.
Step-by-step explanation:
The statement that is true is For each hour that Michelle drove, she traveled an additional 50 miles.
What is a graph?The graph shows the relationship between a distance and the time .
With the graph interpretation, it display the relationship between the number of hours that Michelle is driving as well as the distance, and it can be deduced that it started at 0 hours, and distance of 350 miles
Hence, option B is correct because Michelle drove, an additional 50 miles since at zero y-coordinate was no more distance to cover.

After a parade, a group of volunteers is helping to pick up the trash along a 2-mile stretch of a road. The group decides to divide the length of the road so that each volunteer is responsible for cleaning up equal-length sections. Find the length of a road section for each volunteer if there are 8 volunteers
Answer: 0.25 miles
Step-by-step explanation:
When solving a word question, look for certain words that tell you what you should be solving for, and how to solve it.
In this problem, the group DIVIDES the length of the road EQUALLY, which tells you that in order to solve the problem, you must divide the length of the road by the number of volunteers.
The road is 2 miles long, and there are 8 volunteers, so
8/2 = 0.25
Thus, each person must clean 0.25 miles of road.
Using proportions, it is found that the length of road section for each volunteer will be of 0.25 miles.
-----------------------
This question is solved by proportions, using a rule of three to find the length of the road assigned to each volunteer, as each volunteers will be assigned an equal length of the road.In total, the length of the road is of 2 miles. Thus, 8 volunteers are responsible for 2 miles. For how many miles will a single volunteer be responsible?-----------------------
The rule of three is given by:
8 volunteers - 2 miles.
1 volunteer - x miles
Applying cross multiplication:
[tex]8x = 2[/tex]
[tex]x = \frac{2}{8}[/tex]
[tex]x = \frac{1}{4}[/tex]
[tex]x = 0.25[/tex]
The length of road section for each volunteer will be of 0.25 miles.

Answer:
B. 10 to the third power
The required missing number in 390 x __ = 390,000 is 10³. option B is correct.
The missing number in the calculation 390x__=390,000 is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Mike and Kate plan to save money for their wedding over a 20 month period. They will need to save $8,000 to help pay for the wedding. They set aside the same amount each month. After a year they saved $4,000. Mike and Kate know they must adjust their plan in order to meet their goal, so they came up with the following options:
Option A: Stay with saving the same amount they've been saving each month but postpone the wedding 2 months.
Option B: Increase the amount of money they save each month by $80 from what they've been saving.
Which of the following is a true statement?
Answer:
The Answer is Actually D. I just took the Test and got it Correct! have a Great Day.!!
Step-by-step explanation:
The true statement is that both plans will not amount to $8000 in the end
The target savings is given as:
[tex]Target = \$8000[/tex]
The amount saved after a year is given as:
[tex]Savings = \$4000[/tex]
Start by calculating the amount saved each month (by dividing the saved amount by 12)
[tex]Monthly = \frac{\$4000}{12}[/tex]
For option (A): To increase the wedding by 2 months.
This means that the duration of savings would be 22 months.
So, the estimated savings would be
[tex]Estimate= \frac{\$4000}{12} \times 22[/tex]
[tex]Estimate= \$7333[/tex]
For option (B): Increase savings by $80.
This means that they have 8 months to complete their savings
The estimated savings would be
[tex]Estimate= \$4000 + (\$80 + \frac{\$4000}{12}) \times 8[/tex]
[tex]Estimate= \$7307[/tex]
For both plans, the estimated savings are short of the target savings of $8000.
Hence, none of the plans would amount to $8000 in the end

Sue is offered a job reshelving books in the University of Montana library from noon until 1 p.M. Each Friday. Her reservation wage for this task is $10 per hour. If the library director offers Sue $100 per hour, how much economic surplus will she enjoy as a result of accepting the job? Now suppose the library director announces that the earnings from the job will be divided equally among the 400 students who live in Sue's dormitory. Will Sue still accept? Explain how your answers to parts a and b illustrate one of the incentive problems inherent in income redistribution programs.
Answer:
Step-by-step explanation:
Sue's initial wage per hour = $10
Sue's wage per hour after the increase = $100
a. Economic surplus to be enjoyed = $100 - $10
= $90
Sue would enjoy an economic surplus of $90.
b. No, because in this case the wage per hour for each 400 student would be;
= [tex]\frac{100}{400}[/tex]
= $0.25
= 25 cents
Redistribution of income is the act of equal sharing of wealth among a certain number of people.
The problem here is that Sue would feel cheated with the division of the earnings among 400 students, but very happy when her wages was increased.
Though the income incentive redistribution programs reduce poverty, but it may be unfair.
