Can someone explain please

See below

Step-by-step explanation:

A number is divisible by 4 if the last two digits are divisible by 4.

A number is divisible by 8 if the last three digits are divisible by 8.

So for the first one, the digit would either be 7 or 1 because 72 is divisible by 4 and 12 is divisible by 4. If you notice, 72-12=60, which is also divisible by 4.

For the second one, the digit would be either 1 or 9 because 112 is divisible by 8 and 192 is divisible by 8. If you notice, 192-112=80 which has an 8 in it!

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

answer: it is d
