Answer:
x = –4
Step-by-step explanation:
x = –koef x / (2•koef x²)
Answer:
Inverse of given function = log(x)/log(3)
Step-by-step explanation:
<u>How to find the inverse of any function?</u>
- <em>In the complete function, replace y with "x" and x with "y"</em>
- <em>Then, solve the obtained equation from step 2 for y</em>
- <em>And, then the value obtained for "y" is the inverse required i.e. = f^{-1}(x) </em>
Now, we solve the problem:
Given :- y = 3^x
replacing the value of "y" with "x", we get,
x = 3^y
to solve for "y" we should take the "logarithm" for both sides
log (x) = y log(3)
or y = log(x)/log(3)
or f^(-1) (x) = log(x)/log(3)
Answer:
y=2/3x-5
Step-by-step explanation:
First, let's put this equation into slope-intercept form.
2x-3y=24
-3y=-2x+24
y=2/3x-8
For two lines to be parallel, they must have the same slope. Therefore our slope is 2/3.
Now, we must find b. To do that we can plug the y and the x in.
-7=2/3(-3)+b
-7=-2+b
-5=b
y=2/3x-5
y = 0 . . . . is the equation of the line.
_____
The line shows y to have the same value for every value of x. Thus the value of y is a constant, and there is no dependence on x at all. This is true for any horizontal line. Here, the constant value is zero, so the equation is ...
... y = 0
Answer:
x=13 degrees
Step-by-step explanation:
Since m is parallel to l, 119= (9x+2)
119=9x+2
Subtract 2
117=9x
Divide by 9
13=x
