State the practical meaning of the slope and y-intercept for the situation described. The cost, in dollars, of retaining the services of a computer repairman in Anchorville is given by C = 48x + 18, where x is the number of hours worked. a. 48 signifies the hourly rate, and 18 signifies the overhead charge. c. 18 signifies the hourly rate, and 48 signifies the overhead charge. b. -48 signifies the hourly rate, and 18 signifies the travel cost.

Answers

Answer 1

Answer: The practical meaning of the slope and y - intercept of the linear equation, C = 48x + 18 is that 48x is the variable cost depending on the number of hours and 18 is the fixed cost or the overhead change. Hence, the answer to the question above is letter A.

Answer 2

Answer:

Answer:

answer is A

Step-by-step explanation:

Answer:

Option: c is the correct answer.

c) 70

Step-by-step explanation:

There are two choices in the quality of the item i.e. Cotton or wool.

There are 5 choice of color.

Also there are seven sizes.

Hence, in order to find the total number of items that are needed for a complete assortment we need to use to method of permutation.

i.e. the calculation is:

$2_P_1* 5_P_1* 7_P_1\n\n\n=(2!)/((2-1)!)* (5!)/((5-1)!)* (7!)/((7-1)!)\n\n\n=(2!)/(1!)* (5!)/(4!)* (7!)/(6!)\n\n\n=2* 5* 7\n\n\n=70$

Hence, the answer is:

c) 70

There are two types in five colours so 2x5=10. There are then seven sizes of each so 7x10=70. Your answer is C.70. I really need brainliest answers.

How are expressions and equations different

Answers

An "equation" has a left side, a right side and an equals sign separating the sides. An "expression," by contrast, doesn't have any "sides" and is simply what the name suggests: An algebraic "expression."

Expressions have no equal sign, while equations have equal signs.

The length of a rectangle is 4 more than 3 the width. If the perimeter of the rectangle is 18.4 cm, what is the area of the rectangle?

Answers

im assuming you mean 4 more than 3 times the width so we'll make the width x and the length 3x + 4
perimeter is all of the sides added together so our equation is 2(x) + 2 (3x + 4) because there are two sides for length and two for width. we expand this equation to: 2x + 6x + 8 which equals 8x + 8. this is equal to 18.4 so 8x + 8 = 18.4
subtract each side by 8: 8x = 10.4
divide each side by 8: x = 1.3
if x = 1.3 then the width = 1.3
if the width = 1.3 then the length = 7.9 because 3(1.3) + 4 = 7.9
area is length times width so 1.3 x 7.9 = 10.27
The area is equal to: 10.27
