Step-by-step explanation:

For each value of x you will have a y value

Step 1: Make a Chart with values

X | 1 2 3

Y |

Step 2: Substitute the x values in the y function

y= 2(1) - 1

y=2-1

y=1

Step 3: Fill the Chart with the obtained values

X | 1 2 3

Y | 1

Step 4: Plot the points as coordinates (x, y) i.e (1,1)

Step 5: Connect the points

Step 6: Be happy, you just learn how to plot. You can follow this proccedure for any kind of function.

Answer:

y is the vertical axis. x is the horizontal axis. Replace any value in x to get your y value. The value you input as x is your x value. God this sounds confusing. I'd graph it for you but i don't know how to do that on Brainly.

Ten thousand marbles were produced on a production line. The first 100 marbles off the line were taken and tested for roundness.

Soloha48 [4]

No, it is not. In a simple random sampling, all produced marbles should have the same probability to be taken off the line. In this case only the first 100 marbles are taken while the rest of the production batch is not randomly sampled

The value of 1.7y+37 is 14 less than the value of 9.3y–25

Alinara [238K]

Answer: Yes, it is less than, as the value of the first equation is 14, while the second equation is 100.8

Step-by-step explanation:

1.7y + 37 = 14...........equation 1

9.3y - 25 = ?............equation 2

Find the value of y by subtracting 37 from both sides of equation 1

1.7y +37 -37 = 14 - 37

1.7y = -23

Divide both sides by 1.7

y = 13.53

Insert the value of y into equation 2

9.3 (13.53) - 25

125.83 -25

=100.8
