Answer:
17
Step-by-step explanation:
A graphing calculator is useful for writing a linear equation from a table of values. The one shown below says the table can be represented by the equation ...
y = 2x -3
The graph of the two equations shows the solution is (10, 17).
The y-value of the solution is 17.
2x^2 + 12x
(I think this is the answer, and if you want to simplify it, the simplified/factorised answer would be 2x(x+6)
Answer is 4.) 15 girls.
If you go 27-5-4=18
18-5-4=9
9-5-4=0
so 5+5+5 (because it's 5 girls to 4 boys, only count the 5's) =15
Hope this helps! :)
