In a sequence of numbers, each term except the first is 4 less than 4 times the previous term. If the fourth term in this sequence is 12, what is the first term?

Answers

First term is -1 because the common difference between each term 4n-4 where n is the term before. Therefore of you work backwards by taking 4 away from 12 then diving by 4 you should get 4 as third term. So you can keep going back till first term and you would get the following sequence

-1, 0, 4, 12...

Farmer has 120 bushels of wheat to sell at her roadside stand. She sells an average of 165
8 bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.

Answers

Answer:

The total change in the number of bushels she has for sale after 5 days is 83.125 bushels

Step-by-step explanation:

The given parameters are;

The initial number pf bushels the farmer has = 120 bushels

The amount of bushels of wheat the farmer sells each day = 16⁵/₈ = 16.625

The number of bushels sold after 5 days = 16.625 × 5 = 83.125 bushels

The total change in the number of bushels she has for sale after 5 days = The number of bushels sold after 5 days

The total change in the number of bushels she has for sale after 5 days = 83.125 bushels.

Write the equation of the given line in standard form y=ax+b:The line containing the midpoints of the legs of a right triangle ABC where A (-5,5), B (1,1) and C (3,4) are the vertices.

Answers

Find the distance between the sets of points. 
Use this to determine which sides are the legs.

A to B = sqrt(52) = 7.2111
A to C = sqrt(50) = 7.07106
B to C = sqrt(65)= 8.622577

B to C is hypotenuse

midpoint of A to B is (-2,3)
midpoint of A to C is (-1, 4.5)

The line we are solving for contains these midpoints, so we have to solve for the slope between them and use point-slope form to make the equation of the line.
 slope = 3/2 (or 1.5)
y=m(x-x1)+y1

Find the student’s error in solving the following inequality.31 < –5x + 6
25 < –5x
–5 < x

a. The student should have added 6 to both sides instead of subtracting it.

b. The student divided 25/–5 incorrectly.

c. The student should have switched the direction of the inequality sign to get –5> x for a final answer.

Answers

Answer: c. The student should have switched the direction of the inequality sign to get –5> x for a final answer.

Step-by-step explanation:

From the given steps, the last step is done wrong by student.

When we multiply or divide any negative number on vboth sided of the inequality, the sign of inequality reverse its direction .

In the last step student divide the inequality by -5 but didn't switch direction of the inequality sign.

hence, c is the right option "The student should have switched the direction of the inequality sign to get –5> x for a final answer."
