Answer:
See below
Step-by-step explanation:
"Like terms" are terms with the same variable or exponents.
You can add or subtract these just like you would with regular numbers.
Examples:
2x + 4x = 6x
5xy + 7xy = 12xy
6 + 5 = 11
Let me know if you need more examples or have any questions :)
Answer:
The domain of a function is the complete set of possible values of the independent variable. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
Step-by-step explanation:
When finding the domain, remember:
The denominator (bottom) of a fraction cannot be zero
The number under a square root sign must be positive in this section
The range is the resulting y-values we get after substituting all the possible x-values.
Answer:
One match: 3-0
2nd match: 0-1
3rd match: 0-0
Step-by-step explanation:
We have been given that a hockey team played three matches, scoring 3 goals and received 1 goal. The team won one of the matches, another match was a draw and lost the third.
Since team won 1 mach, lost 1 match and 1 match was draw, so the possible score of 3 matches:
The match, in which team won, the team's score would be 3 goals and opponent's score would be 0 goals. Therefore, hockey team won by 3 goals.
The match, in which opponent team won, the team's score would be 0 goals and opponent's score would be 1 goal. Therefore, opponent hockey team won by 1 goal.
Since third match was a draw, so both teams scored no goals in 3rd match.
-2.1-6x=1.5 add 2.1 to both sides
-6x=3.6 now divide both sides by -6
X= -.6
First off, you really don't need to write "what percent???" here.
25% of 80 is 0.25(80) = 20.
