Answer:
-8x^2 -4x
Step-by-step explanation:
f(x) = –4x – 2
g(x) = 2x
(f · g)(x) = (-4x-2) * (2x)
distribute
= -2x*4x -2x*2
= -8x^2 -4x
Answer:
A. x ≤ 
Step-by-step explanation:
-9x + 2 > 18 or 13x + 15 ≤ -4
-9x > 16 or 13x ≤ -19
x > 
or x ≤
From the choices given, only x ≤ proves to be correct answer.
Answer:
5
Step-by-step explanation:
Using fractions:
= 
+ = 
= 5
Using decimals:
= 2.5
2.5 + 2.5 = 5
<u>Answer:</u>
log7
<u>Step-by-step explanation:</u>
We are given the following expression in terms of log and we are to solve it:
log (14/3) + log (11/5) - log (22/15)
Just to recall, when we divide two values that have the same base, we basically subtract the exponents.
So applying this rule here to get:
(log11 - log5) + (log14 - log3) - (log22 - log15)
= log11 - log5 + log14 - log3 - log2×11 + log5.3
= loh11 - log5 + log14 - log3 - log2 - log11 + log5 + log3
Cancelling out the like terms to get:
= log14 - log2
= log 14/2
= log7
