Answer:
Step-by-step explanation:
for domain x+4≠0
x≠-4
domain={R-{-4}}
R=all real numbers.
y(x+4)=x
yx+4y=x
yx-x=-4y
x(y-1)=-4y
so Range ={R-{-1}}
Answer:
point w
and point x
Step-by-step explanation:
point w is the reflection in the x axis and point x is reflection in the y axis
Answer:
x =-4
Step-by-step explanation:
4x+9 = -2x-15
Add 2x to each side
4x+2x +9 = -2x+2x-15
6x+9 = -15
Subtract 9 from each side
6x +9-9=-15-9
6x = -24
Divide each side by 6
6x/6 = -24/6
x = -4
Here is how you find the answer: (not "bUt JuSt UsE yOuR cAlCuLaToR")
Factor x3−18x+27
x3−18x+27
=(x−3)(x2+3x−9)
Hope this helps!!!!!!!
