The solution would be like
this for this specific problem:
Given:<span> x +y
= 390 </span>
2x + 4y = 1260
2x+4y=1260 ßdivide by 2
= x+2y=630
x+y=390 ßsubtract
= x+2y-x-y=630-390
y=240
x+240=390
x=390-240=150
<span>So, if they raised $1260 from the concession
stand, then they sold 240 sandwiches.</span>
For the axis of symmetry it will be -b/2a but in this case the axis of symmetry is going to be y=4. the x intercept will be the roots (2,0) and (6,0) and for the y intercept it will be (0,3) since the parabola crosses the y axis at (0,3)
3x+12=5x-21
-5x -5x
-2x + 12 = -21
-12 -12
-2x=-33
x = 16.5
