Answer:
Equation: x=2
Solution = 2
Step-by-step explanation:
add like terms so regular numbers like -5 and -3. Add positive 5 to 3 to get 2
And next the variables -2x+3x= x
Answer:
Not equal
Step-by-step explanation:
To find if they are equal, find the product of each first by multiplying each term using exponent rules.
and
These expressions are not the same.

Answer:
See proof below
Step-by-step explanation:
Let x,y be arbitrary real numbers. We want to prove that if x≠y then f(x)≠f(y) (this is the definition of 1-1).
If x≠y, we can assume, without loss of generality that x<y using the trichotomy law of real numbers (without loss of generality means that the argument in this proof is the same if we assume y<x).
Because f is strictly increasing, x<y implies that f(x)<f(y). Therefore f(x)≠f(y) because of the trichotomy law, and hence f is one-to-one.
Step-by-step explanation:
To plot (1,-3), start at the origin (0,0) and move right 1 unit and down 3 units.
