6x+12y+5+2y+8 what’s the coefficient of y and what’s the constant
Rudik [331]

The coefficient of y is 14 and the constant is 13.

You can find this by combining like terms first.

6x + 12y + 5 + 2y + 8

6x + 14y + 5 + 8

6x + 14y + 13

Now the coefficient is the number next to y. The constant is the number on its own.

If f(x) = 2x2 + 2 and g(x) = x2 - 1, find (f - g)(x)I
erastovalidia [21]

9514 1404 393

Answer:

  C. x^2 + 3

Step-by-step explanation:

Substitute for f(x) and g(x) and simplify.

  (f -g)(x) = f(x) -g(x)

  (f -g)(x) = (2x^2 +2) -(x^2 -1) = 2x^2 +2 -x^2 +1

  (f -g)(x) = x^2 +3

This is a continuous set of points in the coordinate plane. It can be, but is not always, straight.
castortr0y [4]

Answer:

Linear. While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value).
