Answer:
Equation of the straight line in point-slope form
y -(-7) = 
(x-8)
Equation of the straight line
3x +4y +4=0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the point ( 8,-7) and 
Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'
y - y₁ = m (x-x₁)
y -(-7) = (x-8)
4( y+7) = -3(x-8)
4y +28 = -3x +24
3x +4y +28 -24 =0
3x +4y +4=0
The symbols, you mean? Those are called "parentheses".
A<span>ngle ADB is 24 degrees and forming triangle BAD, the sum of the angles should be 180.
180- (24+116) = 40 degrees.

Answer:
1.6 meters per second.
Step-by-step explanation:
We have been given an position function 
and we are asked to find the speed of the rock after 1 second.
Derivative of this function will give us speed function.
Now let us find derivative when t=1,
Therefore, the speed of the rock after 1 second will be 1.6 meters per second.
