Answer:
-9
Step-by-step explanation:
We are told in the question that:
Xavier climbs 9 feet up into an apple tree.
The direction symbol or sign for upwards movement = Positive (+) sign
If Xavier would climb back down , he will climb back down 9 feet as well
The direction symbol or sign for downwards movement = Negative (-) sign
Since we know the distance (or how far) he has to climb by downwards is also 9 feet, therefore, the integer that represents the direction and how far he will climb to get back down to the ground is -9
Answer:
Step-by-step explanation:
Basically, in each option, you have to find the relationship between x and y (for one pair). Like in option #1 - how do you get 1.5 from 3? divide it by 2. Now you apply it for all numbers. It the outcome the same? No. 7 ÷ 2 ≠ 3.
You do the same process for all, until you are left with the last one. y = 50x
The last option is the answer.
