Answer: $-\frac{7}{10}$

Step-by-step explanation:

Ordered pairs are written as (x,y)

The difference between the x coordinates is -10

The difference between the y coordinates is -7

Slope is written as $\frac{rise}{run}$

So, the slope is $-\frac{7}{10}$

Answer:

speed of light movement when boat is 1 mile from light house is 0.029 miles/sec

Step-by-step explanation:

Given data:

distance of boat from light house is 2 miles

rate of turning of light is 100 degree per minute

w = 100 degree/min

$w = 100 \times \frac{\pi}{180} rad/min$

w = 1.745 rad/min

w = 0.0290 rad/sec

speed of movement of light $v = w\times r$

$v = 0.029 \times 1 = 0.029 mile/sec$

thus speed of light movement when boat is 1 mile from light house is 0.029 miles/sec

I need help please thanks

Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees
