The equation which is results from taking the square root of both sides of the provided equation is,

<h3>What is the square root?</h3>
A square root of a number is the value which is when multiplicand by itself gives the same value as the number posses.
Let a number is <em>a. </em>Then this number in the form of square root can be written as,
The given algebraic equation in the problem is,

Take the square root, in both sides,

Cancel out the square root with the square of the number as,

Hence, the equation which is results from taking the square root of both sides of the provided equation is,

comparing the relation given
thus y= -2x +1 to the general equation of a line
where y= mx + c
where m is the gradient and c is the intercept on the y-axis.
from the question, the gradient is -2 and since the line is perpendicular, the gradient is given as

so substituting the value of m in to the equation

=

as the gradient
equation of line is given by
y - y1 = m( x-x1)
from the question y1= -2 and x1=1
substitute them
y-(-2) = 1/2 (x -1)
y+2 =1/2 (x-1)
multiplying through by 2
2 (y+2) = x-1
2y +4 = x-1
2y =x-1-4
2y =x-5
x -2y -5 = 0
therefore the equation for the line is x-2y -5=0
Answer: the many shall not be televised
Step-by-step explanation:
Answer:
steps below
Step-by-step explanation:
post here 16 and 17, should be able to do 18 and 19 yourself
16.
y=-8 for x≤-6
y=-1/4 x + 2 for -4≤x≤4
y=4 for x>4
17.
y=-x-4 for x<-3
y=x+1 for -3≤x≤1
y=-6 for x>4
Cos N= 5/13, and tan N=12/5.
