Slope formula: y2-y1/x2-x1
Question 1:
= 14-(-15)/1-(-11)
= 29/12
= 2 5/12
Therefore, the slope is 2 5/12 or 29/12.
Question 2:
= 12-(-19)/-9-16
= 31/-25
= -31/25
= 1 6/25
Therefore, the slope is 1 6/25 or -31/25.
Question 3:
= -3-(-3)/8-(-18)
= 0/26
Therefore, the slope is 0.
Best of Luck!
Answer: The fraction 301/900
Note: I'm assuming the 4's continue on forever
==============================================
Work Shown:
I'm going to assume that the 4s go on forever. I'll represent this with three dots after the last 4 like so
0.334444...
Now let x = 0.334444...
Multiply both sides by 100
x = 0.334444...
100x = 100*(0.334444...)
100x = 33.444444...
And repeat with 1000
x = 0.334444...
1000x = 1000*(0.334444...)
1000x = 334.444444...
Then subtract and solve for x. Notice how the decimal parts line up and cancel
1000x-100x = (334.444444...) - (33.444444...)
1000x-100x = (334+0.444444...) - (33+0.444444...)
1000x-100x = 334+0.444444... - 33 - 0.444444...
1000x-100x = (334-33)+(0.444444... - 0.444444...)
900x = 334 - 33
900x = 301
x = 301/900
Answer:
2
Step-by-step explanation: divide 4 by 2 its 2!
A, because:
Hardcover: 0.35
Buys hard cover and non-fiction: 0.35 x 0.55 = 0.1925
