Using the distance formula, you get sqrt(36+25) which is sqrt(61) which is around 7.8
Answer:
A
Step-by-step explanation:
its the same but switched around
Elevators starts 90 feet below ground level after 15s it is 20 feet below ground level. So the distance it has gone up is 70 feet because 90-20=70. Use this common equation: speed =distance/time and put your values in to get the correct answer. Time is 15s. You can eliminate c and d before you even start as the elevator is moving upwards. For the questions below just use a calculator.
When rounding always look at the number after the decimal . Anything 5 & up is rounded to the next number and anything below 5 is rounded down .
I think the correct answer is -8x+4
explanation:
This would be considered a rise over run. So you see where the line hits the point on the y intercept (thats where the four came from) and you count down until you see where the point hits on the x intercept ( thats where the negative 8 came from) and you go over one because thats where the point was, so you can write -8/1 or you can just do -8x.
