Is (4,3) a solution to 2x-y < 4?

Sub the point into the inequality
2(4)-3<4
8-3<4
5<4
Therefore, no, it is not a solution because 5 is not less than 4
Hope this helps!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
