x=4
Step-by-step explanation:
2log(x)+log(5)=log(80)
log(x^2)+log(5)=log(80)
log(5x^2)=log(80)
5x^2 =80
x^2 =80/5
x^2=16 , taking square root both sides
x=√16
=4
Answer:
2
Step-by-step explanation:
You can rewrite thosee two equations as -9x+12=-6, because f(x)=f(x)
Now isolate x
-9x+12=-6
-9x+12-12=-6-12 (subtract 12, subtraction property of equality)
-9x=-6-12
-9x=-18 (simplify)
-9x/-9=-18/-9 (divide by 9, division property of equality)
x=2
