-0.2k = -15 ( then divide -0.2k on both sides)
The answer is then k= 75
Salutations!
Insert brackets to make this calculation right 4x2+5-3
The brackets should be inserted outside 2+5. If you add brackets outside teh rest of the numbers the calculation would not make sense.
4 × (2 + 5) - 3
Hope I helped (:
have a great day!
No, you can not separate:
ln ( 7 + x ) ≠ ln 7 + ln x
You can separate just if you have a logarithm of multiplication.
For example:
ln ( 7 · x ) = ln 7 + ln x
So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.
