Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes

r-ruslan [8.4K]

Answer:

The equation has two zeros because the discriminant is greater than 0.

Step-by-step explanation:

3x^2 – 7x + 4

a=3 b = -7 c=4

The discriminant is

b^2 -4ac

(-7)^2 - 4(3)(4)

49 - 48

Since the discriminant is greater than zero, there are two real solutions

At Ree Ski Center, the most people will pay for a neck warmer is $10. The manager of Ree Ski Center knows he needs a 30% markup

taurus [48]

Let $x$ be the most the manager can pay the suppliers.

Then, we know from the information given in the question that the manager needs a 30% markup based on cost.

Therefore, the guiding equation will be:

$x+\frac{30}{100}x\leq 10$

because $10 is the most people will pay for a neck warmer.

Thus, the above equation will become:

$x+0.3x\leq 10$

$1.3x\leq 10$

$x\leq \frac{10}{1.3}=7.69$

$\therefore x\leq 7.69$

Thus, the most a manager can pay the suppliers for neck warmers and still keep the selling price at $10 is $7.69
