What is the value of the discriminant for the quadratic equation 0 = x + 2 + x^2?

aliya0001 [1]

Answer:

The discriminant of the quadratic equation is -7.

Step-by-step explanation:

We are given the following quadratic equation in the question:

$x^2+x+2 = 0$

Comparing to general quadratic equation:

$ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2$

We have to find the discriminant of the quadratic equation.

Formula:

$d = b^2-4ac$

Putting values, we get,

$d = (1)^2 - 4(1)(2) = 1 - 8 = -7$

Thus, the discriminant of the quadratic equation is -7.

Anna is a teacher at an elementary school. She purchased 73 tickets to take the first-grade children and some parents on a field

Svetllana [295]

She bought 54 child tickets and 19 adult tickets.

Step-by-step explanation:

No. of tickets purchased = 73

Cost of tickets = $771

Cost of one child ticket = $9

Cost of one adult ticket = $15

Let,

Child ticket = x

Adult ticket = y

According to given statement;

x+y=73 Eqn 1

9x+15y=771 Eqn 2

Multiplying Eqn 1 by 9;

$9(x+y=73)\\9x+9y=657\ \ \ Eqn\ 3\\$

Subtracting Eqn 3 from Eqn 2;

$(9x+15y)-(9x+9y)=771-657\\9x+15y-9x-9y=114\\6y=114\\$

Dividing both sides by 6;

$\frac{6y}{6}=\frac{114}{6}\\y=19$

Putting y=19 in Eqn 1

$x+19=73\\x=73-19\\x=54\\$

She bought 54 child tickets and 19 adult tickets.
