y = -1/3(x – 2)(x + 3)
y = -1/2 (x + 2)(x – 3)
y = 1/4 (x + 2)(x – 3)
Answer:
y = - 1/2 (x + 2)(x – 3) is the right answer
Step-by-step explanation:
The price of senior citizen ticket is 8 and price of student ticket is 14.
Two or more expressions with an Equal sign is called as Equation.
Let x be the price of senior citizen ticket
y be the price of student ticket.
On the first day of ticket sales the school sold 4 senior citizen tickets and 5 student tickets for a total of $102.
4x+5y=102..(1)
The school took in $126 on the second day by selling 7 senior citizen tickets and 5 studenttickets.
7x+5y=126..(2)
Subtract equation 1 and 2
4x+5y-7x-5y=102-126
-3x=-24
Divide both sides by 3
x=8
Now let us find y
4(8)+5y=102
32+5y=102
Subtract 32 from both sides
5y=102-32
5y=70
y=14
Hence, the price of senior citizen ticket is 8 and price of student ticket is 14.

If 5x + 7 = -13, then x = -4.
The contrapositive of this statement would be: "If x does not equal -4, then 5x + 7 will not equal to -13."
The contrapositive is defined as the inverse and converse of a conditional statement.
X is equal to 4 we know this is because the sign in between the number means greater than or equal to so 3 x 4 equals 12 which makes the equation on right true and on the left x.
So, the contrapositive of this statement would be:
"If x does not equal -4, then 5x + 7 will not equal to -13."
