Answer:

y2= 2x-4

y3=6x-1

y4= x-1

y5=2x

Step-by-step explanation:

for y=2x-1

1) for a vertical translation down of 3 units

y2= y-3 =(2x-1)-3= 2x-4

y2= 2x-4

2) for a slope increased by 4

y3= y+ 4x = 2x-1 +4x = 6x-1

y3=6x-1

3) for sloped divided in half. slope of y : m=2 → slope of y4=2/2 =1

y4= x-1

4) shifted up (vertical translation) of  1 unit

y5= y+1 = 2x-1+1=2x

y5=2x

You estimate that there are 44 marbles in a jar. The actual amount is 73 marbles. Find the percent error.
Svetlanka [38]

Answer:

Percentage Error in counting the marbles in the jar is 39.72%

Step-by-step explanation:

Estimated marbles in the jar = 44

Actual marbles in the jar  = 73

⇒Error in  Marbles  =  Number of actual Marbles - Estimated marbles

                                 =   73  - 44 = 29

So, the error in counting marbles in the jar is 29.

Now, \textrm{Percentage Error}  = \frac{\textrm{Error in the Data}}{\textrm{Actual Data}}  \times 100

= \frac{29}{73}  \times 100  = 39.72

or, Percentage Error  =  39.72%

Hence, the Percentage Error in counting the marbles in the jar is 39.72%

What is the recursive rule?
julsineya [31]

Mr. Red's salary is an illustration of an arithmetic sequence

The recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000

<h3>How to determine the recursive formula?</h3>

From the complete question, we have the explicit rule of Mr. Red's salary to be

an = 500n + 29500

Where:

  • First term, a1 = 30000
  • Common difference, d = 500

The above means that:

The difference between a term and the next term is 500.

So, the recursive rule is:

an = an−1 + 500

Recall that:

a1 = 30000

Hence, the recursive rule of the sequence is (d) an = an−1 + 500; a1 = 30000
