Answer:

let the number of door tickets be x

so, eventually the number of advanced tickets will be. x-30

the total cost=2630.

(x-30)3+5x=2630

3x-90+5x=2630

8x-90=2630

8x=2630+90

8x/8=2720/8

x=340

x-30

340-30

310.

total tickets sold=310+340=650

Therefore, the total tickets bought was 650, 310 was advanced and 340 was door tickets

Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?

Slope Formula: $\frac{y_2-y_1}{x_2-x_1}$

So remember that perpendicular lines have slopes that are negative reciprocals to each other and parallel lines have the same slope. To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

$\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}$
