Determine whether each simplification is true or false and why

13 is false. When you distribute and simplify, it becomes t+1-2=t which becomes t-1=t which is not true.

15 is true. Simplified down, it becomes 10n+5-5=10n, which becomes 10n=10n which is true.

It has a slope of 1 nd a y intercept of -2

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"
