Y=2x+3
for x = -3 y = 2*(-3)+3=-6+3=-3
for x = -1 y = 2*(-1)+3=-2+3=1
for x = 2 y = 2*2+3 = 4+3 = 7
for x = 4 y = 2*4+3 = 8+3 =11
for x = 5 y = 2*5+3 = 10+3 =13
4 hours equals 12 miles
1 hour equals 3 miles
All you would need to to is do 13+23= 33 to get the total amount of people who dropped out, then do 72 ( the number in the beginning and subtract 33 from it because those are the people who dropped out so 72-33=39. 39 people finished the race.
Yes they form a proportion the rate of change is 27.5
4*27.5=110
10*27.5=275
18*27.5=495
30*27.5=825
Answer:
you put 3x and 9 on the left side of the box then you put 5x and 9 on the top of the box then you multiply 3x and 5x which is 8x and you put that in your first square... then you do the same its a pattern did i explained ok or good..
