In which of these numbers is the total value of the digit 8 equal to 1/10 the value of the 8 in 587,140

While you did not give possible answers, any number with an 8 in the thousands place would work.

Examples of these would be 18,000 or 7,908,123. Notice in both of these examples, the 8 is in the fourth spot from the decimal.

Every spot closer to the decimal becomes 1/10 of what it way further away.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
