Solve the math problem

Mathematics
1 answer:
Kisachek [45]3 years ago
3 0

Answer:

See below & pic.

Step-by-step explanation:

Now I understand the problem.

I corrected the answers I had given you, and wrote them in the blanks, and I filled in the rest a drew the graph.

See the picture below.

I think the question is not the cost and the earnings per hour. Rathe it means the cost and earnings as a function of hours.

I wrote those equations. Then I filled in the tables.

The breakeven point, when cost and earnings are equal, is at 6 hours, when both cost and earnings are $54. That is where the two lines intersect in the graph.

Answer: (i) 4x - 40 = 76

(ii) 29 questions

Can you help me with a question? What is the equation of the blue line?
Artist 52 [7]

Answer:

y = -x - 1

Step-by-step explanation:

y = mx + b

<u>slope (m):</u> Since the line is going downhill, the slope will be negative

slope = rise / run

slope = 1 / 1

slope = 1

m = -1

<u>y - intercept (b):</u> this when x = 0, the line is crossing the vertical line (y-axis)

b = -1

so y = mx + b is

b = -1, m = -1

y = (-1)x + (-1)

2^3+5x(6+4)÷2, for MATH LIB
Lynna [10]

Evaluate 2^3+5x(6+4)÷2 following Order of Operations rules (PEMDAS):

Work within parentheses is done first, followed by exponentiation, and then mult. and div., and finally add'n. and subtr'n.

Thus, 2^3+5x(6+4)÷2 becomes 2^3+5x(10)÷2

8 + 50x/2

adding and subtracting one step equations. A dividing board is 12.4 feet above the ground. The bottom of the pool is 16.9 feet b
melisa1 [442]

Answer:

The distance is 29.3 feet

Step-by-step explanation:

Here, we want to find the distance from the diving board to the bottom of the pool

To get this, we will need to add the height of the diving board above the ground plus the distance of the bottom of the pool below the ground

Mathematically, we can have this as:

12.4 + 16.9

= 29.3 feet
