Answer:
x=4 (solution) x=-14 (extraneous solution )
Step-by-step explanation:
|x+5|=9 -------original equation
Equation can be equal to +9 and -9
x+5 =9 x+5 =-9
x= 9-5 x=-9-5
x=4 (solution) x=-14 (extraneous solution )
for checking
x+5 = 9 x + 5=9
4+5= 9 -14+5=9
9=9 -9=-9
12a. Answer: d) x⁶ f'(x) + 6x⁵ f(x)
<u>Step-by-step explanation:</u>
Use the multiplication formula for derivatives:
y = a · b → y' = a'b + ab'
<u>y = x⁶ · f(x) </u>
a = x⁶ b = f(x)
a' = 6x⁵ b' = f'(x)
<u>y' = a'b + ab'</u>
y' = 6x⁵ f(x) + x⁶ f'(x)

12b. Answer: 
<u>Step-by-step explanation:</u>
Use the division formula for derivatives:
→ 

Note: You can also move the denominator to the top (it will have a negative exponent) and use the multiplication formula for derivatives.
Answer:
18
Step-by-step explanation:
you can do 12/2 to get 6 (the scale factor) and then multiply 3 by 6 and get 18
It would be 10000010. Have a good day
Answer: 2
