Answer:
a10 b10
Step-by-step explanation:
Exponent is the expression in where you convert product factor expression into a shorter expression. So really you use it to make the question simpler and shorter(easier to understand).
To approximate the distance of points with three dimension, make use of the equation,
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2 +(z2 - z1)^2)
Substituting all the data from the points given,
<span>d = sqrt ((2 - -2)^2 + (-7 - 3)^2 +(4 - -5)^2) = sqrt 197
</span>
Thus, the distance from the points is approximately 14.04 and that is letter D.
Remember solving inequalities is setting up two smaller inequalities one positive one negative. Also, when you divide or multiply by a negative number to solve for x the inequality changes over.
Answer:
(a) 
(b) 
(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
Step-by-step explanation:
We have given points are 
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through 
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by 
So 

(b) Equation of line is given 
This line is parallel to x axis so slope will be zero
So equation of line will be 

(c) Answer of part a is equation of line
which is parallel to y axis and in part by equation of line is
which is parallel to x axis
