2 cards from this section. Quick, good the night before a test.
Form a pair of linear equations for the scenario: "John bought 3 apples and 4 bananas for $2. If he bought 5 apples and 2 bananas it cost him $1.50."
Use the costs involved to create your equations.
Which of these pairs of equations [2x + y = 5, 4x + 2y = 10] are consistent?
Check the ratios of coefficients.
What do you call a pair of linear equations that has no solution?
Think of the scenario of parallel lines!
Is a dependent pair of equations consistent or inconsistent?
Reflect on the concept of coincident lines.
A farmer has a total of 100 animals consisting of cows and goats. If cows are double in number compared to goats, find out how many of each kind there are.
Set up the total as a single equation.
Two equations represent the same line but in different formats. Show their forms and demonstrate their infinite solutions.
Transform both equations to confirm their equivalency.
