Answer:
C
Step-by-step explanation:
The function f(x) = -1/3x - 5 will be verbally described using the words for the operations of multiplication and subtraction. These words would include difference, product, decrease, subtracted, less than and times. The options include:
A. The function value is the difference between x times -1/3 and 5.
This is the equation since it separates the -1/3x and 5 terms using the word and.
B. The function value is 5 less than the product of x and 1/3.
This is the equation since it separates the -1/3x and 5 terms using the word and.
C. The function value is -1/3 of x subtracted from 5.
This is NOT the equation since it DOES NOT separate the -1/3x and 5 terms using the word and. It also suggests 5 - 1/3x by subtracting from 5.
D. The function value is -1/3 of x decreased by 5.
Though this doesn't use the word and, it separates the -1/3 and 5 terms by the order and still subtracts 5.
Answer:
<h2><u><em>
15 cm</em></u></h2>
Step-by-step explanation:
Find the length of a square that is equal in area to a rectangle measuring 45cm by 5 cm
45 x 5 = 225 cm²
- length of the square = √A
√225 = <u><em>15 cm</em></u>

Answer: w = 4, l = 5
Step-by-step explanation:
area of a rectangle = lw
l = 2w - 3 based on question
area = (2w-3)w multiply through parentheses
area = 2w^2 - 3w
area = 20 plug in area
20 = 2w^2 - 3w
move all terms to one side
2w^2 - 3w - 20 factor
(2w+5)(w-4) set both terms equal to 0 and solve
w = -2/5, 4
w can only be positive so w = 4
plug w into l
l = 2w - 3= = 2 * 4 - 3 = 5
