Answer:
C
Step-by-step explanation:
The big triangle and small triangles are similar so their corresponding sides are in proportion.
x/15 = 15/9
x= 15*15/9
x=25
Slope = (y2 - y1)/(x2 - x1)
slope = (-3 -4)/(1 - 1)
slope -7/0
This is an undefined slope because the denominator is 0.
This would be a vertical line.
Answer:
74 weeks
Step-by-step explanation:
Given :
Let x = number of weeks
Gallon A:
Capacity = 666
Leak rate = 4 gallons per week
666 - 4x
Gallon B:
Capacity = 888
Leak rate = 7 gallons per week
888 - 7x
666- 4x = 888 - 7x
666 - 888 = - 7x + 4x
-222 = - 3x
x = 222 / 3
x = 74
After 74 weeks
None of the answers are correct. The correct answer would be x=(P-25)/2
