Answer:
it is C
Step-by-step explanation:
Let Kaya's savings be 30x and Edgardo's savings be 35x
If they both started saving at the same time:
f(x)=30x
f(x)=35x
Now, sub in values for x in to the function starting with 0. Subtract y2-y1 and x2-x1 for both functions.
For slope: m=y2-y1/x2-x1
so your result will be m=30/1=30 for f(x) = 30x
and m=35/1=35 for f(x) = 35x
so the slopes are m=30 and m=35 respectively!
To get the 0.12 to repeat, the trick is to subtract 1 from the denominator
Then reduce the fraction.
now add the 3 to get
A is the answer since if you graph it, it has those points, or you may just simply plug in the x points that are given and see if they equal the y number
