Consider the quadratic equation 2x2 + 3x + 5 = 0.

Anastaziya [24]

Answer:

The discriminant of this quadratic equation is less than zero.

This means the quadratic equation will have no real solution(s) and two complex solution(s).

Step-by-step explanation:

The discriminant is found using the formula b^2 - 4ac.

Therefore, the discriminant is (3)^2 - 4(2)(5), which yields -31.

Since the discriminant is negative, there are no real solutions.

set up and solve a system of equations to solve the problem The school band sells carnations on Valentine's Day for $3 each. It

sasho [114]

Answer:

Number of carnations = 6

Step-by-step explanation:

Let the number of carnations school band buys from florist be x.

Cost of each carnation = $0.50

Total cost for x number of carnations = $0.50x

Also , delivery cost = $15

So, total cost on buying x number of carnations from florist = 0.50x + 15

Now,

School band sells carnations at a price of $3 each.

Total revenue they get get after selling x number of carnations = $3x

We need to find that , when will the cost of the carnations be equal to the revenue from selling them.

i.e 3x = 0.50x + 15

or 3x - 0.50x = 15

or 2.50x = 15

or x = $\frac{15}{2.50}$

or x = 6

so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue
