Answer:
Step-by-step explanation:
Rational numbers:
-are all numbers you can write as a quotient of integers ,
-include terminating decimals. For example,
-include repeating decimals. For example,
Irrational numbers:
-have decimal representations that neither terminate nor repeat. For example,
-cannot be written as quotients of integers
The answer is D
Have you ever heard of rise over run rise/run
Y/x. Well in this case the run is One with a rise of four
2t = 40 - 2w
t = 40/2 (-2/2)w
t = 20 - w -- rearrange
t = -w + 20
t + w = 15
t = -w + 15
same slope, different y intercepts.....parallel lines, no solutions
