I believe it would be "y"
Step-by-step explanation:
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Answer:
f(x) = x² - 81 = ( x+ 9)(x - 9) Difference of two squares
g(x) = x+9/x-9
g(x) . f(x) = x + 9/ x - 9 × (x+9)(x - 9)
= ( x + 9)(x +9)
= ( x + 9)²
= x² + 18x + 81
Hope this helps.
Answer:
m=-1
Step-by-step explanation:
Since you no what x is you can subst. it into the second equation so 2m+11-9=0 so 2m+2=0 then subtract 2 from both sides 2m=-2 than divide m=-1
Answer:
s = u/tv
Step-by-step explanation:
To make s the subject of the formula in the equation of; u = tsv
,just divide both sides by (tv)...in which on the right hand side...it will cancel out t and v,hence leaving only s and then only the left hand side..it will give you your answer;
; u = tsv
; u/tv = tsv/tv
; s = u/tv
