Answer:
120 ft
Step-by-step explanation:
A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.
x/1000 = 12/100
x = 120 ft
Answer:
b = 
Step-by-step explanation:
Given
a = 4b +
- b, that is
a = 3b + 
Multiply through by 3 to clear the fraction
3a = 9b + 2 ( subtract 2 from both sides )
3a - 2 = 9b ( divide both sides by 9 )
= b
Answer: -10, 30
Explanation: I found the median of x and y and put it together
If 4 is a root, then a factor must be x - 4.
Only choices A and D have x - 4 as a factor.
Now look at the constant term of each binomial in the factorizations of choices A and D.
A.: -4, 4, 5
Their product is -80.
The constant term of the original polynomial is -40, so this factorization cannot be correct.
D.: -4, 2, 5
Their product is -40.
This is the correct factorization.
Answer: D.
