ROC is often used when speaking about momentum, and it can generally be expressed as a ratio between a change in one variable relative to a corresponding change in another; graphically, the rate of change is represented by the slope of a line.
Oh okay have a good night !
Answer:
800+700+700+3000 is what will get you your answer 5200 is your answer
Step-by-step explanation:
You can see almost immediately that the second equation, 3x + y = -2, can be solved for y: y = -3x - 2. (Answer A). This -3x - 2 can in turn be subbed for y in the first equation, 4x + 3y = 4. Doing so, we get 4x + 3(-3x - 2) = 4.
Carrying out the indicated opeations: 4x - 9x - 6 = 4, or -5x = 10. Thus,
x = -2. Find y using y = -3x - 2 (from above): y = -3(-2) - 2 = 4.
Thus, the solution is (-2,4). We were not asked to solve this system of equations, but doing so illustrates the helpfulness of elimination of variables in solving simultaneous equations.
For this question, we want to match the width of the smaller rectangle with the width of the larger rectangle, and we want to match the length of the smaller rectangle with the length of the larger rectangle.
Thus, we have two possible answers.
OR
Thus, B is our answer.
