Select the correct answer. For which quotient is x=7 an excluded value?
Lisa [10]

Answer:

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

Step-by-step explanation:

Given

See attachment

To answer this question, we start by equating the denominators of each option to 0; then, solve for x

(a):

\frac{7x}{x^2 - 10x + 21} / \frac{x + 7}{7}

This gives

\frac{7x}{x^2 - 10x + 21} * \frac{7}{x + 7}

Set the denominator to 0

(x^2 - 10x + 21)(x + 7) = 0

Solve for x

(x^2 - 7x - 3x + 21)(x + 7) = 0

Factorize:

(x(x - 7) - 3(x - 7))(x + 7) = 0

(x - 7)(x - 3)(x + 7) = 0

This implies that:

x = 7\ or\ x = 3\ or\ x = -7

From above, one of the values of x is 7.

This implies that x = 7 is an excluded value for this quotient.

Suppose the new actual number of pizzas sold today was 60. The original previous day sold was 65. Describe the number of pizzas
Lady bird [3.3K]
Answer: 1) Pizzeria must sell 78 pizzas for receiving the bonus.
2) The number of pizzas sold is decreased by Approximately 7.69 %.
Step-by-step explanation:
1) The number of pizza sold yesterday = 65,
The target for receiving the bonus = 20% more than the number of pizza sold yesterday
= 20% more than 65,
= 65 + 20% of 65 ( 1% = 0.01 ⇒ 20% = 0.2 )
= 65 + 0.2 × 65
= 65 + 13 = 78.
Hence, they must sell 78 pizzas for receiving the bonus.
2) If the actual number of pizza sold today = 60
⇒ Total reduction in the number of pizza = 65 - 60
= 5
Thus, the percentage decrease in the number of pizza
