Answer:
4y--7 i think
Step-by-step explanation:
Answer:
The system of equations is inconsistent because there's no solution.
Step-by-step explanation:
7y = 11.2x + 28 is a multiple of y = 1.6x + 4. Thus we have the same equation at the end.
Multiply y = 1.6x + 4 by 7.
7y = 11.2x + 28... Equation 1
7y = 11.2x + 28... Equation 2
Subtract equation 2 from 1.
7y - 7y = 11.2x - 11.2x + 28 - 28
0 = 0 + 0. There's no solution for x and y.
Answer:
The correct answer is Option 3: 12y
Step-by-step explanation:
A polynomial term is usually made of a variable and a co-efficient.
Like terms are those terms that have the same variables i.e. x and 44x are like terms.
Given expression is:
All the terms have only y which means that all three terms are alike.
The coefficients of like terms are added or subtracted according to their sign.
= 12y
Hence,
The correct answer is Option 3: 12y
