Answer: x = -26
Step-by-step explanation:
3x-47
substitute x with 7: 3(7)-47
3(7) = 21 -47 = -26
Answer:
lnx/ln4
Step-by-step explanation:
Given
y=4^x
In order to find the inverse of the function the first step is to replace the y with x and x with y
So,
Replacing x with y and y with x
x= 4^y
We have to find the value of y explicitly to find the invers.
The above equation can also be written as:
4^y=x
As the variable is in exponent, to bring it down, ln has to be taken on both sides.
ln 4^y =ln x
The power of will be multiplied with the ln.
y ln4=lnx
y=lnx/ln4
So,
The inverse is lnx/ln4 ..
Answer:
y-1=2(x-3)
Point slope form is Y-y1=m(X-x1)
M= slope
y1= the y co-ordinate of your point
x1= the x co-ordinate of your point
Answer:
y = 9x^2 + 12x - 12.
Step-by-step explanation:
y = (3x - 2)(3x + 6)
y = 9x^2 - 6x + 18x - 12
y = 9x^2 + 12x - 12.
Hope this helps!
