  5a. parallel lines

  5b. distinct non-parallel lines

  5c. the same line (twice)

  6. x-3y=21; 9x+3y=9

Step-by-step explanation:

5. a. "Inconsistent" equations have no solution. As lines on a graph, they are parallel lines. (Any parallel lines will do.)

5. b. "Consistent and Independent" lines are distinct lines that are not parallel. (Any non-parallel lines will do.) They don't have to cross each other on this graph, but they need to have different slopes.

5. c. "Consistent and Dependent" lines are the same line. How you show two lines being the same line is up to you. You could label them as such, or perhaps you could draw a dashed line on top of a solid line. You need to communicate to your teacher that you know the two lines are the same.

6. We can let 'x' represent "a number", and 'y' represent "a second number". Then the given relations are ...

  x -3y = 21

  9x +3y = 9

(These have the solution (x, y) = (3, -6).)

im like 90% sure its a meme

step-by-step explanation:

good luck tho

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
