If their slopes are the same, the line are parallel, which means in number 3 and 5 the lines are parallel.
If one slope is the reciprocal of the other one with opposite sign, then they are perpendicular. Fir example lines with these slopes are perpendicular: 8/9 and -9/8
So, in number 4, 8 and 10 lines are perpendicular.
Well the dependent variable is .75, and the independent variable is 10.
So,
.75x + 10 would be the equation, the number of miles representing x.
Answer:
2/5 or 0.4
Step-by-step explanation:
rise over run is 20/50, simplifies to 2/5
Answer:
5 feet each
Step-by-step explanation:
So we know that 4 pieces of rope out of 5 are equal. So, we simply subtract 10 from 30 for that 10-foot piece of rope, which leaves us with 20. Divide 20 by 4 (since there is 4 pieces of rope of equal value) and it leaves us with 5 feet.
Hope I helped! :)
