Answer:

Step-by-step explanation:

4/5-(-3/10)=4/5+3/10=8/10+3/10=11/10

5.5-8.1=-2.6

-5-5/3=-15/3-5/3=-20/3

-8 3/8-10 1/6=-67/8-61/6=-445/24

-4.62-3.51=-8.13

In the table below, x represents the miles traveled and y represents the cost to travel by train.
Afina-wow [57]

Answer:

Third option

m = 2.25

Step-by-step explanation:

The slope of the function is equal to its rate of change between two points.

For example, for a couple of points (x_1, y_1),\ (x_2, y_2)

The slope is:

m =\frac{y_2-y_1}{x_2-x_1}

In this problem we have the following points

1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)

We calculate the slope between the first two points

m =\frac{15.25-8.50}{5-2}=2.25

We calculate the slope between the points 3 and 4

m =\frac{31-22}{8-4}=2.25

We calculate the slope between the points 2 and 3

m =\frac{22-15.25}{8-5}=2.25

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

PLEASE HELP
shtirl [24]

Answer:

70 m

Step-by-step explanation:

AB makes a 30-60-90 triangle with the wall.

AC makes a 45-45-90 triangle with the wall.

In a 30-60-90 triangle, the short leg (opposite of the 30° angle) is half the hypotenuse.

In a 45-45-90 triangle, the legs are the same length.

So the distance between the left wall and the laser is 60/2 = 30 m.

The distance between the right wall and the laser is 40 m.

The total distance is therefore 70 m.

The sign would be negative

X is in the negative area meaning that when x/y and multiplied by y, it would stay negative since y is positive
