(a) y >_ 13
(b) x > 17.5
Explanations:
(a)
24.2 - y <_ 11.2
- y <_ 11.2 - 24.2
-y <_ -13
y >_ 13
(b)
- 12.5 + x > 5
x > 5 + 12.5
x > 17.5

The definition of a rational number is:
Any number that can be made by building a fraction
using whole numbers.
You can make 0.123 that way. Here's the fraction: 123/1000
It's also handy to know that any number that's completely
written down using digits ... and a fraction bar or a decimal
point if they're needed ... is a rational number. This is not a
definition, and it doesn't cover all rational numbers, but it's
handy sometimes.
It's also handy to know that a decimal that has a set of digits
after the decimal point that repeats forever is a rational number,
even though you can't completely write it down (because it never
ends).

Step-by-step explanation:
Answer:
y=1+-2 then simplify
Step-by-step explanation:
9x+3y=3
first dicide so
2x+y=1
now move 2x to other side
so it would turn negative
put in point slope form-y=mx+b
y=1+-2×
