Please help me, thank you Question 7 options:
From the library, one car heads north, and another heads east. Some time later, the northbound car has traveled 17 miles, and the eastbound train has traveled 144 miles. The two cars, measured in a straight line, are ___ miles apart.

145 miles apart

hope this helps

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
