Ē Example 3
» Claire bought 8 tickets for a total cost of $104.
She had used a coupon code to get $3 off each
ticket. Let x be the original cost of each ticket.
Which of the following equations correctly
represents the situation?
Drag tiles to complete the callouts.
3(x - 8) = 104
Cost of one ticket
8x - 3 - 104
104
Total cost
8(x - 3) = 104
Average cost
$3 discount times
the difference of
8 tickets and the
cost per ticket
8 tickets times
the difference
of the cost per
ticket and $3.
8 tickets times
the cost per ticket
minus a total
discount of $3

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
