3x+2y=18
8x+6y=50
2y=18-3x
Y=9-3/2x
8x+6 (9-3/2x)=50
8x+54-9x=50
-x+54=50
X=4
Y=9-3/2 (4)
Y=9-6
Y=3
X < 4

There would be an open circle above the 4 on the number line and then shade everything to the left of it and making sure to include the arrow at the end pointing to the left.
Answer:
9000 - 500m
Step-by-step explanation:
Your original number is 9000. It starts to decrease at a rate of 500 feet per minute. So we know that you will subtract 500 from 9000 but we don't know how many times. Because of this, we will put a variable to represent the minutes that we are descending.
In conclusion: 9000 - 500m
