Masja [62]3 years ago
5 0

Answer:

B. (-2, -6)

Step-by-step explanation:

The constant term is the product of the values in the solution set. (Both A and B give 2·6 = 12.)

The coefficient of the x term (8) is the opposite of the sum of the values in the solution set. That is, the solutions add up to -8.

... A: 2+6 = 8 ≠ -8 . . . . <em>not</em> the solution set

... B: -2 +(-6) = -8 . . . . these values are the solution set.

The solution set is (-2, -6).

Yuri [45]

Question:

A cafeteria offers oranges, apples, or bananas as its fruit option. It offers peas, green beans, or carrots as the vegetable option. Find the number of fruit and vegetable options. If the fruit and the vegetable are chosen at random. what is the probability of getting an orange and carrots? Is it likely or unlikely that a customer would get an orange and carrots?

Answer:

The probability of getting an orange and carrots is \frac{1}{9}

Step-by-step explanation:

The fruits offered in cafeteria = oranges, apples, or bananas.

The vegetables offered in cafeteria  = peas, green beans, or carrots.

There are 3 fruits and 3 vegetables . Therefore the total possible number of  outcomes is  = 3 \cdot 3 =  9

Now the probability of getting an orange and carrots = \frac{1}{9}

The possibility is very unlikely to happen
