It is Irrational because is can not be written as a fraction
800= about 1.76 lbs
700= about 1.54 lbs
(there are about 453.5 grams in a pound
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
Answer: 1848 feet per minute
<u>Step-by-step explanation:</u>

Answer:
The first set is a solution, the second is not.
Step-by-step explanation:
Testing by filling in the numbers into the equation:
(1, 1.5): x=1, y=1.5
⇒ 1.5 =?
· 1 +
⇒ 1.5 =?
+
⇒ 1.5 =?
⇒ 1.5 =? 1.5 ⇒ Correct: is indeed solution to the equation
(12, 4): x=12, y=4
⇒ 4 =?
· 12 +
⇒ 4 =?
+
⇒ 4 =?
⇒ Incorrect: this is not a solution for the equation
