The drama club is selling tickets to the play to raise money for the shows expenses. Each student ticket sales for five dollars each and each adult ticket sales for $7.50 each the auditorium and hold no more than 75 people the drama club must make a minimum of $450 from ticket sales to cover the shows cost if X represents the number of students tickets sold and Y represents the number of adult tickets sold right and solve any systems of inqualities

45 student tickets and 30 adult tickets

Step-by-step explanation:

You can check your work by plugging both answers into both of the original equations. :)

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
