Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest

Answer:
y = -4x + 1
Step-by-step explanation:
you said, slope of -4, therefore it's -4x and you also said y intercept of 1, therefore it's a positive 1 : +1
combine them together: y = -4x +1

3(5x+2)=8x+20
15x+6=8x+20
15x-8x=20-6
7x=14
then you divide both sides by 2
The answer is 2.
Left one i think thats the one
