Answer:
12/7
Step-by-step explanation:
When given two points, we can find the slope by using
m = (y2-y1)/(x2-x1)
= (4 - -8)/ (0 - -7)
= (4+8) / (0+7)
= 12/7
Answer: A
Step-by-step explanation:
Answer:
28%
Step-by-step explanation:
Hello,
When the item is reduced by 10%, this is like we multiply this price by 1-0.10=0.90
When the item is reduced by 20%, this is like we multiply this price by 1-0.20=0.80
When the item is reduced by 10% and then by 20%, this is like we multiply this price by 0.90*0.80=0.72
so this is equivalent that the item is reduced by 28% (as 1-0.28=0.72)
hope this helps
