Hey there can you help me out on this question
andre [41]
Discriminant of a quadratic equation can be calculated as:

Discriminant = b² - 4ac

b = coefficient of x term = 2
a = coefficient of squared term = 1
c = constant = 7

So,

Discriminant = 4 - 4(1)(7) = -24

So, the correct answer to this question is option C

The bookstore at suntan U Had a sale on school t shirts. Thursday they sold 45 of the marked down t-shirts for a total of 406.50
Kisachek [45]

Answer:

The number of women's shirt sold is 32.

The number of men's shirt sold is 13

Step-by-step explanation:

Total number of T shirts sold on Thursday = 45

Total amount it was sold for :  406.50

Cost of each women's t shirt = 9.25

Cost of each men's t shirt = 8.50

Here, let the number of women's shirt sold= k

So,number of men's shirt = Total shirts sold - Women's shirt

= 45 - k

Also, total amount earned = Amount earned from men's shirt + amount earned from women's shirt

or, 406.50  =  k(9.25) + (45 -k)(8.50)

⇒ 406.50 = 9.25 k - 8.50 k +  382.5

or, 24 =  0.75 k

⇒ k = 24/0.75 = 32

Hence, the number of women's shirt sold is 32

And the number of men's shirt sold = 45 - 32  = 13
