Answer:
Step-by-step explanation:
A 'like term' for 7y must have the variable y in it, but would have a different coefficient.
For example: 11y and 7y are like terms: same variable, different coefficients.
That isnt even a question is a mathematical statement
Ohms law states V=IR
I is current and R is resistance
We are given V=120 and R=30
Therefore 120=I*30 or I=40A
C is the independent variable because it is all by itself.
