Answer:(5,8)
Step-by-step explanation: you just move5 to the rigth to get 3 and move 8 down to get -1
1) We can determine by the table of values whether a function is a quadratic one by considering this example:
x | y 1st difference 2nd difference
0 0 3 -0 = 3 7-3 = 4
1 3 10 -3 = 7 11 -7 = 4
2 10 21 -10 =11 15 -11 = 4
3 21 36-21 = 15 19-5 = 4
4 36 55-36= 19
5 55
2) Let's subtract the values of y this way:
3 -0 = 3
10 -3 = 7
21 -10 = 11
36 -21 = 15
55 -36 = 19
Now let's subtract the differences we've just found:
7 -3 = 4
11-7 = 4
15-11 = 4
19-15 = 4
So, if the "second difference" is constant (same result) then it means we have a quadratic function just by analyzing the table.
3) Hence, we can determine if this is a quadratic relation calculating the second difference of the y-values if the second difference yields the same value. The graph must be a parabola and the highest coefficient must be 2

Answer
x=15, y=48
Step-by-step explanation:
let two nos are x and y
y-3=3x
3x-y=-3...........(1)
also, x+y=63.............(2)
from (1), y=3x+3
y=3x+3 put in equ (2)
x+3x+3=63
4x=63-3=60
x=15=smaller no
y=45+3=48
larger no y=48
x=15, y=48 answer
Answer: 3 chewy fruit worms cost 0.30 dollars. 300 chewy fruit worms cost 30 dollars. you can buy 100 chewy fruit worms for 10 dollars. you can buy 500 chewy fruit worms for 50 dollars. the unit price for a chewy fruit worm is 0.10 dollars. The unit rate is 1:0.10.
