Step-by-step explanation:
If your question is x² + 5xy
Then,
Numerical coefficient = Number in the given expression
Numerical coefficient = 5
Option A
Answer:
log4x+log4(x-6)=2
place under single log using multiplication rule
log4(x(x-6))=2
convert to exponential form:(base(4) raised to log of number(2)=number(x(x-6)
4^2=x(x-6)
16=x^2-6x
x^2-6x-16=0
(x-8)(x+2)=0
x=8
or
x=-2 (reject, x>0)
Step-by-step explanation:
It says the sum, which hints that the two numbers will be added
So we can start the equation with 10+(1/3n)
we are then told they add up to 25
So they will equal 25
So the equation is
10+(1/3n)=25

Answer:
1/2
Step-by-step explanation:
The midpoint is the average of the end points:
(-3 +4)/2 = 1/2
The coordinate of the midpoint is 1/2.
Replace f(x) with y:
y = 3x +2
interchange the variables:
x = 3y +2
switch the equation so the Y is on the left side:
3y +2 = x
subtract 2 from each side:
3y = x-2
divide each term by 3 to get y alone:
y = (x-2)/3
replace y with inverse of F(x) which is f^-1(x):
f^-1(x) = -(x-2)/3
