Answer:
The co-ordinates of K¹( -1 , -2 )
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given that the point K( -2,1 )
<em>when rotating a point 90° about the origin </em>
Given point A(x,y) transformation to A¹( - y,x )
Given point K(-2,1) → K¹ ( -(1) , -2)
<u><em>Final answer</em></u>:-
<em>The co-ordinates of K¹( -1 , -2 )</em>
Step-by-step explanation:
x +
x + x - 1

x
Simplify 
(((3 • (x3)) + 5x) -
) + 1
3.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using x as the denominator :
3x^3 + 5x (3x^3 + 5x) • x
3x^3 + 5x = ———————— = ——————————————
1 x
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
4.1 Pull out like factors :
+ 5x
x}{x}[/tex]
5.1 Adding a whole to a fraction
Rewrite the whole as a fraction using x as the denominator :
1 1 • x
1 = — = —————
1 x
The sum can be rewritten as y=4x, where y=f(x).
Now, we can rewrite the equation a x=y/4
Therefore, inv(f(x))=x/4
