URGENT Determine the value of k for which the line 3y + k = 3x is a tangent to the
curve y = 2x2 – 2x + 5.
Solution: k=?

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
