You want to use the addition property, so you need to ADD each term. Just change the minuses to pluses, making sure you keep the negative with the number


5x-8x-7y+y =

5x + -8x + -7y +y

How do you find the area of a triangle ?
katovenus [111]

Answer:

to find the Area of a Triangle, you have to multiply the base times the height of the triangle to find the Area.

Step-by-step explanation:

For example..

If the Base ( bottom part of the triangle) was 10 and the height ( the vertical line of the triangle) was 5, you would multiply them together to get 50. So 5o would be the area of the Triangle.

The velocity of a 150 kg cart changes from 6.0 m/s to 14.0 m/s. What is the magnitude of the impulse that acted on it?
tatuchka [14]
<span>An impulse is the change in momentum. Momentum is mass times velocity. Because the mass does not change, a change in velocity is what creates an impulse. (14.0 m/s - 6.0 m/s) = 8.0 m/s. (150 kg)x(8.0 m/s) = 1200 kgm/s.</span>

Y = 2 - 4x input output
tester [92]

Every function is a rule which tells you how to associate inputs and outputs. The input, also known as independent variable, is often indicated with the letter x, while the output, also known as dependent variable, is often indicated with the letter y.

With this notation, we write y = f(x), read "y is a function of x", in the sense that the value of the variable y depends on the value of the variable x, and f is the function that tells you how y depends on x.

In your example, you have y = f(x) = 2-4x, which means "subtract four times the input (4x) from 2"

So, it doesn't matter which input you chose (i.e. the value for x), because you will always have to behave this way:

  • Pick an input value, x
  • Multiply it by four to get 4x
  • Subtract this number from 2: 2-4x

Here are some examples of explicit calculations: if I choose x = 2 and input, the workflow will be

  • Pick an input value, 2
  • Multiply it by four to get 8
  • Subtract this number from 2: 2-8=-6

So, if the input is 2, the output is -6

Similarly, if we choose x = 0 as input, we have:

  • Pick an input value, 0
  • Multiply it by four to get 0
  • Subtract this number from 2: 2-0=2

So, if the input is 0, the output is 2. And so on: for every possible value for x you have the correspondant value for y, with the function f telling you how to associate one with the other.
