15/3x =5
x= 5
5+2y= 315
5-5+2y =315-5
2y = 310
2y/2 = 310/2
y=155
Step-by-step explanation:

2x+4y=450
2×5=10
10+(4×155)
=620/155

Answer:
-(x-4)x(3X-5)
Step-by-step explanation:
The answers are A, C and D
Answer:
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
Step-by-step explanation:
Given the table
x y
0 3
1 4
2 7
3 12
The (first) difference, let suppose denoted by d, of y values can be obtained by taking the difference between consecutive terms.
The second difference, let suppose denoted by d₂, can be obtained by taking the difference between consecutive terms of the first difference of y-values, such as:
