Which equation could be used to create the data shown in the table?y = 4x + 1
y = 5x
y = 5x + 1
y = x + 4

table

x y
1 5
4 17
5 21
7 29
9 37

Answers

Answer 1
Answer:

Answer with explanation:

The table is

 x y

1 5

4 17

5 21

7 29

9 37

→→Ratio of Difference between y value and x value or slope which is equivalent to back statement is

   =(17-5)/(4-1)=(21-17)/(5-4)\n\n=(29-21)/(7-5)=(37-29)/(9-7)=4

Slope between two points is same.So, the following points represents straight lie.

Equation of line is given by

    \rightarrow y-y_(1)=m(x-x_(1))\n\n\rightarrow y-5=4 (x-1)\n\ny-5=4 x-4\n\n4 x-y+5-4=0\n\n4x-y+1=0\n\ny=4 x+1

Option A: y=4 x+1                          

Answer 2
Answer: equation could be used to create the data shown in the table is the first equation y = 4x + 1

kedar earns a monthly salary of $2,200 plus a 3.75% commission on the amount of his sales at a mens clothing store. what would he earn this month if he sold $4,500 in clothing? round off to the nearest cent

Answers

$2200 + 3.75% of $4500 would be 2200 + 0.0375 x 4500 or $2200 + $168.75

2200 + 168.75 = $2368.75

Answer:

2368.75 total cost

Step-by-step explanation:

3.75% divided by 100 = 0.0375.

Then 4500 X 0.0375= $168.75.

2,200 + 168.75 = 2,368.75.

                                                                      = 2,368.75 total cost.

What is (-0.75x + 6) -(2.5x -1.9)

Answers

The solution to the expression (-0.75x + 6) -(2.5x -1.9) is -3.25x + 7.9

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

(-0.75x + 6) -(2.5x -1.9)

Open teh brackets

So, we have

(-0.75x + 6) -(2.5x -1.9) = -0.75x + 6 -2.5x + 1.9

Evaluate the like terms

So, we have

(-0.75x + 6) -(2.5x -1.9) = -3.25x + 7.9

Hence, the solution is -3.25x + 7.9

A basketball player made 9 out 12 foul shots. What percent of his foul shots did he make?

Answers

A basketball player made 9 out 12 foul shots The basketball player made 75% of his foul shots.

To find the percentage of foul shots the basketball player made, we can use the following formula:

Percentage = (Number of successful shots / Total number of shots) * 100

In this case, the basketball player made 9 successful shots out of 12 total shots.

Percentage = (9 / 12) * 100

Now, calculate the percentage:

Percentage = 0.75 * 100

Percentage = 75%

So, the basketball player made 75% of his foul shots.

Suppose you plan to purchase 10 items that each cost 4.45. Explain how you use mental math to to find the cost of 10 items

Answers

Answer:

44.5

Step-by-step explanation:

Multiplying 10 with 4.45 using mental math to find the total cost of 10 items. first multiply 0 with 445 which will yield 000, then multiply 1 with 445 which will yield 445 now put a cross beneath last 0 in 000 and write 445 before it and perform addition which will yield 4450 as the decimal was initially was before the second last digit in 4.45, place it accordingly in 4450 which will yield 44.5.

The answer is A, because:
The dimentions in cm are 5cm by 3cm, so you make that to scale. The page says that 1cm is equal to 5m, so you multiply both numbers by 5 and you get 25 by 15. If you need clarification, let me know.
The answer is a because to get the length of the sides you do 7-4 which is 3 times five is 15m. To find the base you do 2 times 3 times 5 which is 25m. A) 25m. * 5m.
