Answer:
Step-by-step explanation:
-3m*n+4m-3 when m=2:n=-2
-3(2)*(-2)+4(2)-3=
12+5=17
Answer:
2cnd one 3rd one 4th one last one
Step-by-step explanation:
Answer:
For example 
Step-by-step explanation:
A non-unit fraction is a fraction of which the numerator is not equal to one. Additionally, the question does not state to pick three different ones and thus you can pick any fraction that when multiplied by three (since you take three fractions together) add up to a whole number (I'm picking the whole number to be one here just to make it simple), where the numerator is not equal to one of course.
For example: , because 3· = 
= 1
Infinitely many solutions can be found: for example 
An expression that represents how the four friends would split a bill of ’x’ dollars is: x/4
If their total bill was $124.00:
124/4 = 31
Each friend should pay $31.00
Answer: B. The domain is {x|x<0 or x>0} and the range is {y|y>0}
Step-by-step explanation:
f(x)=x^-2
----------------------------
#1 Any negative (-) exponents means the answer will be 1/ the term
- for example, 3^-2=1/3^2=1/9
NOTE: NEGATIVE EXPONENTS DOES NOT MEAN IT IS A NEGATIVE NUMBER, IT IS STILL A POSITIVE NUMBER IF THE BASE IS POSITIVE.
-----------------------
The domain, which will be the value of x.
x can be any real number, except 0, because 0 can't go to negative exponents or else it will be undefined.
{x|x<0 or x>0}
-------------------------------------
The range, which will be the value of y.
Since the x value is being squared, it is always positive
{y|y>0}
