Each week you will have a question that you must answer.
The questions are worth 10 points each. The first person to correctly answer the question each week will get 5 bonus points.
YOU MUST USE AT LEAST THREE SENTENCES TO EXPLAIN YOUR ANSWERS.
(5,2) is not a solution for the linear system: 2x-3y=4 2x-8y=11 When you substitute 5, and 2 for x and y, only 1 of the equation is correct like dionjare said. 2(5)-3(2)=4 True 2(5)+8(2)=26 False
The first one is true 2(5)-3(2)=4 because 2(5) equals 10 and 3(2) equals 6 and 10-6=4, but the second one isn't 2(5)+8(2)=16 not eleven because 2(5) is 10 and 8(2) is 16 and 10+16=26.
There are several good ways to solve systems of linear equations. And the best method to use in any given situation is the one that requires the least amount of work. However, that will depend on the particular equations that you’re trying to solve. The most popular methods are inspection, elimination, substitution, intersection,
I agree. The method I like to use the most is elimination. Another one is graphing. turning something like -4x+2y= 14 into 2y=4x+14..... to y=2x+7 which, as David and Andrew said, is y=mx+b form. The last one is substitution.
2(5)-3(2)=4
ReplyDelete10-6=4 true
2(5)+8(2)=11
10+16=11 not true, because (5,2) isn't a solution for the 2nd equation its not a solution for the linear system
(5,2) is not a solution for the linear system:
ReplyDelete2x-3y=4
2x-8y=11
When you substitute 5, and 2 for x and y, only 1 of the equation is correct like dionjare said. 2(5)-3(2)=4 True 2(5)+8(2)=26 False
2(5)-3(2)=4 is true but
ReplyDelete2(5)+8(2)=11, and that is not true. The second equation equals 26. Therefore, not a solution.
Very Good guys:
ReplyDeleteNew Question:
Name three different methods that you can use to solve Linear Equations
The first one is true 2(5)-3(2)=4 because 2(5) equals 10 and 3(2) equals 6 and 10-6=4, but the second one isn't 2(5)+8(2)=16 not eleven because 2(5) is 10 and 8(2) is 16 and 10+16=26.

ReplyDeleteThe three methods you can use to solve linear equations are elimination, substitution, and graphing.
ReplyDeleteThe three methods you could use would be elimination,substitution, and graphing or intersecting lines, That is what you could use.
ReplyDeleteGraph it- change to y=mx+b
ReplyDeleteTo fill in- substitute the numbers in for X&Y
Eliminate- Eliminate.
The three methods to solve a linear equation is elimination substitution and graphing which means to turn it into y=mx+b form
ReplyDeleteI agree. The method I like to use the most is elimination. Another one is graphing.
ReplyDeleteturning something like -4x+2y= 14 into 2y=4x+14..... to y=2x+7 which, as David and Andrew said, is y=mx+b form. The last one is substitution.
I agree with everyone that said the 3 methods to a a linear equation are substitution, elimination and graphing.
ReplyDeleteI agree with everyone. The 3 methods are substitution, elimination, and graphing.

ReplyDeleteI agree with Aubrey, Because three methods you can use are : Graphing, elimination, and substitution.
