Answer:
Step-by-step explanation:
P1(3,3)
P2(1, -5)
M= (-5-3)/(1-3)=-8/-2=4
Y=4x-9
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
P <span>≤ </span>450$ Rebecca can only pay equal to 450$ or less than 450$ so she can only afford A and B
Using the definition of vertical angles you can set up the equation 3x+4=115, when solved you get x=37. Hope this helps!
