1. Multiply each amount of money by the number of jewelry. :120x15=1800 90x9=810 60x10=600 15x3=45.
2. Add all the amounts of jewelry together. : 15+9+10+30=64
3. Add all the answers in step 1 together. :1800+810+600+45=3255
4. Divide your answer in step 3 by the answer in step 2: 3255/64=50.859375
5. 51.0 is your answer if you round it up!!
I know this is correct! I worked this myself twice!!
Hope this helps!!:)
Assuming you're asking "for which values of the function has an inverse that is a function", the answer is "all the odd exponents ".
Infact, if is even, you have that
and so is not injective, and thus not invertible
On the other hand, if is odd, we have:
- is continuous.
- The first two points tell us that the function is surjective.
- Moreover, the derivative is . Since is even, we have , thus the function is always increasing, and so the function is also injective.
- Injective and surjective means bijective, and the function can be inverted.
Answer:
The square root of 49 is rational
Step-by-step explanation:
If we take the square root of 49, we get 7, which is a rational number.
Answer:
5
Step-by-step explanation:
Answer:
y=1/2x+5
Step-by-step explanation:
Plug it into the formula for a point and a slope.
(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))
Y-8=1/2(x-6)
Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.
