3x + 2y = -3
Which equation could be used?
Answer:
Step-by-step explanation:
He could use either. It would probably be better to use one that already has a variable without a coefficient. which one has that? Let me know if that doesn't make sense.
Do 96 divided by 6.
6 goes into 96 16 times. therefore, your answer is 16
substitute the coordinates of the ordered pair into either equation to see if it produces a true statement
B.
substitute the coordinates of the ordered pair in both equations to see if it produces a true statement for each
C.
substitute the coordinates of the ordered pair in the first equation to see if it produces a true statement
D.
substitute the coordinates of the ordered pair in the second equation to see if it produces a true statement
Answer:
B
Step-by-step explanation:
When an ordered pair is a solution to a system of equations in two variables, it must mean that when you plug in the ordered pair into both equations, it must come out true (this is literally the definition of a solution to a system of equation). Technically, A is also facts, but B is a "more inclusive" facts so that's your answer. Hope this helps! :)
Step-by-step explanation:
Well, to reduce a fraction to lowest terms, divide the numerator and denominator by their Greatest Common Factor. This is also called simplifying the fraction.
To find the Greatest Common Factor, you must:
1. List the prime factors of each number.
2. Multiply those factors both numbers have in common. If there are no common prime factors, the GCF is 1.
