Ainat [17]

Solving for y:
4x-3y=10. (subtract 4x on both sides)

Answer:

D = 51, other = 30

Step-by-step explanation:

d = | 5 1 |

|-1 10|

D = (5 x 10) - ( 1 x -1) = 50 + 1 = 51

| 2 4|

|-3 9|

(2 x 9) - (4 x -3) = 18 + 12 = 30

Rachel hikes at a steady rate from a ranger station to a campground that is 20 mi away. After 2 h, she is 13 mi from the campgro

Angelina_Jolie [31]

Answer:

-3.5

The distance Rachel covers per hour is 3.5 miles

Step-by-step explanation:

After 2 hours, she is 13 miles from the campground.

After 4 hours, she is 6 miles from the campground.

Let x be the number of hours, y be the number of miles from the campground, then we have two points (2,13) and (4,6).

The equation of the line passing through the points $(x_1,y_1)$ and $(x_2,y_2)$ is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute:

$x_1=2\\ \\y_1=13\\ \\x_2=4\\ \\y_2=6$

Hence,

$y-13=\dfrac{6-13}{4-2}(x-2)\\ \\y-13=-3.5(x-2)\\ \\y=-3.5x+7+13\\ \\y=-3.5x+20$

The slope of the line is $-3.5$ and it represents that the distance Rachel covers per hour is 3.5 miles.
