What are the solutions (coordinate points) to the system of equations?

  (-2, 0), (0, 6)

Step-by-step explanation:

A graphing calculator answers this easily. (See attached.) Solutions are (-2, 0) and (0, 6).

_____

Equate the expressions for y and solve the resulting quadratic.

  x^2 +5x +6 = 3x +6

  x^2 +2x = 0 . . . . . subtract 3x+6 to put in standard form

  x(x +2) = 0 . . . . . . factor

Values of x that make this true are x=0 and x=-2. The corresponding values of y are most easily found using the linear equation for y:

  y = 3·0 +6 = 6 . . . . . (x, y) = (0, 6) is a solution

  y = 3(-2) +6 = 0 . . . . (x, y) = (-2, 0) is a solution

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
