Answer 1

Answer: 1. I would call quadrants i, ii, iii, iv as a, b, c, d

2.Which type of variables are usually on the y-axis and represent output?
they usually are the dependent variables, that is, they depend on the x value, such as velocity, price, income.

3.Which type of variables are usually on the x-axis and represent input?
those are the independent variables such as time, distance, price.

4.Which type of slope is represented on a graph as a horizontal line?
the slope of an horizontal line is zero.

5.Find the slope of 2x + 4y = 12
the general form of the line is:
4y = - 2x + 12
y = -(1/2)x + 3

hence the slope is -1/2

Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.

Answers

Answer:

adult tickets 6.9

children tickets 3.9

Step-by-step explanation:

3x + y = 24.60 L1

5x + 4y = 50.10 L2

5L1 - 3L2

15x + 5y = 123

-15x - 12y = -150.3

-7y = -27,3

y = -27,3/-7

y = 3.9

3x + y = 24.60

3x + 3.9 = 24.60

3x = 24.60 - 3.9

3x = 20.7

x = 20.7 / 3

x = 6.9

How many inches are in 13 and a half feet

Answers

The best way to work this is out, is to find out how many inches there are in a foot, and half a foot. One foot is equal to 12 inches, and half a foot is equal to 6 inches. It's best to find the whole numbers first. The best way to do this is to simply multiply the length (12in) by the feet (13), 13x12= 156 inches.
You've then got half a foot, which is six inches, so you then have to add this to the 156, giving you 162.
In thirteen and a half feet, there are 162 inches,
Hope this helps :)
