Question 1

What phrase can be used in place of √176?

Accepted Answer

4√11

Answer

To simplify the square root of 176, you need to find the largest perfect square factor of 176. The number 176 can be expressed as the product of 16 and 11 (16 × 11 = 176). Therefore, √176 can be rewritten as √(16 × 11), which simplifies to √16 × √11, resulting in 4√11.

Question 2

What expression can be used in place of 64x2 – 225?

Accepted Answer

(8x – 15)(8x + 15)

Answer

The expression 64x² – 225 is a classic example of a difference of two squares. Recognize that 64x² is the square of 8x, and 225 is the square of 15. Applying the difference of squares formula, a² – b² = (a – b)(a + b), we factor the expression as (8x – 15)(8x + 15).

Question 3

Which of the following best depicts the equation of the line that crosses (32,24) and (-10,-8)?

Accepted Answer

y = 16/21x – 8/21

Answer

To find the equation of the line, first calculate the slope (m) using the two given points (32, 24) and (-10, -8). The slope is (24 - (-8)) / (32 - (-10)) = 32 / 42 = 16/21. Then, use the point-slope form y - y₁ = m(x - x₁) with one of the points, for example (32, 24): y - 24 = (16/21)(x - 32). Simplifying this equation yields y = 16/21x - 8/21.

Question 4

In a grocery store, a customer purchased 58 products for a total of $4.20. Bananas made up the majority of the products, with some apples included.

‥ Each apple costs $0.05
‥ Each banana costs $0.10

Which set of equations may be used to determine, from the customer's purchases at the grocery shop, a) the number of apples and b) the number of bananas?

Accepted Answer

a + b = 58
0.05a + 0.10b = 4.20

Answer

Let 'a' represent the number of apples and 'b' represent the number of bananas. The first equation represents the total number of items purchased: a + b = 58. The second equation represents the total cost based on the price of each item: 0.05a (cost of apples) + 0.10b (cost of bananas) = 4.20 (total cost). This system accurately models the given scenario.

Question 5

Which of the following represents 6x² – 17x + 5 in factored form?

Accepted Answer

(2x – 5)(3x – 1)

Answer

To factor the quadratic expression 6x² – 17x + 5, we look for two binomials that multiply to this trinomial. By testing combinations of factors for 6x² (e.g., 2x and 3x) and 5 (e.g., -5 and -1), we find that (2x – 5)(3x – 1) correctly expands to 6x² - 2x - 15x + 5, which simplifies to 6x² – 17x + 5.
