What is the equation of the line that passes through the point (4,-4) and has a slope of -3?
zhuklara [117]

The equation of the line that passes through the point (4,-4) and has a slope of -3 is y = -3x + 8.

<h3>How to find the equation of a line?</h3>

The equation of a line can be represented in slope intercept form as follows:

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore, the equation of the line that passes through the point (4,-4) and has a slope of -3 can be found as follows;

m = -3

Hence,

y = -3x + b

using (4, -4) let's find the y-intercept.

-4 = -3(4) + b

-4  = - 12 + b

b = -4 + 12

b = 8

Therefore, the equation is y = -3x + 8

Keith is racing his little sister Pattie and has given her a 15 foot head start. She runs 5ft/sec and he is chasing at 8ft/sec.
hodyreva [135]
Pattie runs at 5 ft/sec
She has got a head start of 15 feet.
So after 1 second, Pattie runs = (5+15) ft <span>                                                   
                                                  = 20 </span> ft
After 2 second Pattie runs = (20+5)ft
                                           = 25 ft
After 3 second Pattie runs = (25+5) ft
                                           = 30 ft
After 4 seconds Pattie runs = (30+5) ft
                                             = 35 ft
After 5 seconds Pattie runs = (35+5) ft
                                             = 40 ft
After 6 seconds Pattie runs  = (40+5) ft
                                             = 45 ft
Now Keith runs at 8 ft/sec
After 1 second Keith runs = 8 ft
After 2 second Keith runs = (8+8) ft
                                           = 16 ft
After 3 second Keith runs = (16+8) ft
                                           = 24 ft
After 4 second Keith runs = (24+8) ft
                                          = 32 ft
After 5 second Keith runs = (32+8) ft
                                           = 40 ft
After 6 second Keith runs = (40+8) ft
                                           = 48 ft
So Pattie will stay ahead of Keith upto 4 seconds. In the 5th second Pattie and Keith will be level and in the 6th second Pattie will be overtaken by Keith.

Two cars are driving away from an intersection in perpendicular directions. The first car's velocity is 777 meters per second an
salantis [7]

Answer:

The rate of change of the distance between the cars at that instant is 5.46 meters per second

Step-by-step explanation:

Speed of first car = 7 m/s

Speed of second car = 3 m/s

At instant, distance of first car from intersection = 5 meters

distance of second car from intersection = 12 meters

Therefore, we have

Distance between both cars at intant = √(12² + 5²) = 13 m

Rate of cahnge of distance is given by;

2ddd/dt = d(x² + y²)/dt = 2xdx/dt + 2ydy/dt

= 26dd/dt = 2×5×7 + 2×12×3 = 142

dd/dt = 142/26 = 5.46 m/s.

That is the rate of change of the distance between the cars at that instant = 5.46 meters per second.
