I'm not good at explaining things but I do know how to do the problem
5. 2x-3y=-24
x+6y=18 -> -2(x+6y=18) = -2x-12y=-36
distribute -2 ^
2x-3y=-24 x+6(-4)=18
-2x-12y=-36 x -24 = 18
0-15y= -60 +24 = +24
-15 = -15 x= 42
y = 4 (42,4)
6. x-2y=5
3x-5y=8
x-2y= 5 -> -3(x-2y=5)
-3x+6y= -15
3x-5y=8 x-2y=5
0+ 1y= 7 x-2(7)=5
1 = 1 x-14=5
y = 7 +14= +14
x = 19 (19,7
Be just a bit clearer, please: "find the vertex."
You could either "complete the square" or use the "quadratic formula."
Here the coefficients are a=-1, b=11 and c=-18. Because a is -, the curve opens downward and the vertex is on top, representing the function's maximum.
Use the quadratic formula with the coefficients given above.
-b plus or minus sqrt(b^2-4ac)
x = -------------------------------------------
2a
The answer is 2.16 because 12.62 + 0.34 = 12.96 then 12.96 divided by 6 = 2.16 (please make me brainlyest)
