Answer:
a = -8 + sqrt(10)/ 10
Step-by-step explanation:
-4log(a+8)=2
Divide each side by -4
-4/-4log(a+8)=2/-4
log (a+8) = -1/2
Raise each side to the power of 10
10 ^ log(a+8)= 10^-1/2
a+8 = 1/ sqrt(10)
Subtract 8 from each side
a +8-8 = -8 + 1 /sqrt(10)
a = -8 + 1/sqrt(10)
We do not like sqrt's in the denominator
a = -8 + sqrt(10)/ 10
3x + 17 - 5x = 12 - (6x+3)
4x + 17 = 9
4x = -8
X = -2
Answer:
So, sorry
Don't know this type of question.....
Step-by-step explanation:
Given
f(x) = |x + 2|
g(x) = - (x)²
Now
(g•f) (3) = g ( 3 + 2 )
= g(5)
= - (5)²
= -25
Hope it will help :)
