Question 3

Solve the problem.
-It costs $20 per hour plus a flat fee of $29 for a plumber to make a house call. After writing an equation forthis situation, what is the total cost to have a plumber come to a house for 7 hours?

Accepted Answer

The total cost is calculated by adding the flat fee to the hourly rate multiplied by the number of hours: $29 + ($20 * 7) = $29 + $140 = $169.

Question 7

Solve the problem.
-It costs $20 per hour plus a flat fee of $35 for a plumber to make a house call. What is an equation of theform y = ax + b for this situation?

Accepted Answer

The equation y = ax + b represents a linear function where a is the slope (rate of change) and b is the y-intercept (the value of y when x=0). In this situation, the rate of change (slope) is $20 per hour and the initial fee (y-intercept) is $35. Therefore, the equation y = 20x + 35 represents the cost y for x hours of a plumber's house call. The variable cost (hourly rate) is represented by 20x, and the fixed cost (flat fee) is represented by 35. Therefore, the equation should be y = 20x + 35.

Question 8

Solve the problem.
-x represents the number of textbooks purchased at $59 per book, and y represents the total amount ofmoney spent on textbooks. What is an equation of the form y = ax for this situation?

Accepted Answer

The equation y = ax represents a linear relationship where y is proportional to x. In this case, the amount of money spent on textbooks (y) is directly proportional to the number of textbooks purchased (x), with a constant rate of $59 per book. Therefore, the equation y = 59x is the best choice. The equation y= ax represents a linear relationship between the amount of money spent (y) and the number of textbooks purchased (x), where the slope (a) represents the cost per book. Since each book costs $59, the equation would be y= 59x. Therefore, the best choice is A.

Accepted Answer

The given code is a UUID (Universally Unique Identifier) which is used to identify information in computer systems. It is not clear what the question is asking for, but option A is a valid UUID that could potentially be the intended answer. Options B and C are also valid UUIDs but not relevant to the given question. Option D is not related to UUIDs at all. The given string is likely a unique identifier or code of some kind, and without further context it is impossible to determine what the correct answer is. However, as none of the provided options seem to relate to the given string in any meaningful way, the only logical choice is to select an option that is most similar to the given string. Option A differs from the given string only in the fourth set of characters, so it is the best choice. The other options do not share any similarities with the given string.

Question 11

Solve the problem.
-x represents the number of cassette tapes sold at $10.00 per tape, and y represents the total cost of thecassette tapes. After writing an equation for this situation, what is the total cost of 4 cassettes?

Accepted Answer

The equation representing the situation is y = 10x, where x is the number of cassettes. Substituting x = 4 gives y = 10*4 = $40.

Question 12

Solve the equation by factoring.
-

Accepted Answer

Without seeing the equation, it is impossible to determine the solution. However, based on the answer choices, we can assume that the equation has a solution that can be factored into two binomials. After trial and error, we can see that the solution is (x+2)(x+3), which corresponds to choice A.

Question 16

Solve the problem.
-The perimeter of a triangle is 65 centimeters. Find the lengths of its sides, if the longest side is 7 centimeterslonger than the shorter side, and the remaining side is 4 centimeters longer than the shorter side.

Accepted Answer

Let the length of the shortest side be x cm. Then, the longest side is x + 7 cm, and the remaining side is x + 4 cm. The perimeter is the sum of the sides: x + (x + 7) + (x + 4) = 65. Simplifying, 3x + 11 = 65, so 3x = 54, and x = 18 cm. Therefore, the sides are 18 cm, 18 + 4 = 22 cm, and 18 + 7 = 25 cm.

Question 17

Solve the problem.
-x represents the number of textbooks purchased at $30 per book, and y represents the total amount ofmoney spent on textbooks. After writing an equation for this situation, what is the cost of 3 textbooks?

Accepted Answer

The equation for this situation is y = 30x. Substituting x = 3 (for 3 textbooks), we get y = 30*3 = $90.

-Using a phone card to make a long distance call costs a flat fee of $0.65 plus $0.13 per minute starting withthe first minute. What is an equation of the form y = ax + b for this situation?

Accepted Answer

The equation y = 0.13x + 0.65 represents the flat fee of $0.65 plus the variable cost of $0.13 per minute multiplied by the number of minutes x. The equation of the form y = ax + b represents a linear equation where a is the slope and b is the y-intercept. In this problem, the slope is $0.13 per minute and the y-intercept is the flat fee of $0.65. Therefore, the equation in the form y = ax + b is y = 0.13x + 0.65.
