When Martha's brother George spilled milk on her math homework, most of the ink smeared beyond recognition. Martha could only see two points left in her table of values, (5,8) and (12,36). Martha still had to find the equation representing the values in her table, but now, with only two data points, she is not sure she can.
Help Martha out: either (1) explain what information she needs to determine the equation, and why she needs that information, or (2) explain to Martha how to find the equation representing the data when she only has two points, and calculate the equation for her.
For both options type your answer in the text box. If you choose option 2 show your work for finding the equation in the sketch box.

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45 

The answer is in the image 

The answer is in the image 

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

The solution is given in the image below

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km

30% of 420 are first year students

first year students = (30/100 )*420

=126 students

Student who are not in first year = 420-126

=294 students  

tip=18% of 75.45

     =18/100 * 75.45 = $13.581

Tip = $13.581
