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

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
