Step-by-step explanation:
Look at the picture for explanation.
This isn't necessarily true. When two lines have equivalent slopes, then they are parallel and will never intersect.
y=1/2x + 12
y=1/2x + -2
These lines can't intersect because there are equal slopes.
Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
