Answer:
-3
Step-by-step explanation:
First, you can factor out a 6:
Next, you can factor the quadratic:
Since the only value of x that could set this equation equal to 0 is -3, that is the answer. Hope this helps!
The answer is C. y= 3/2 x. You can check by multiplying 3/2 by 3, if you get 7, it is correct
Answer:
(1) 2 (2) (-1/2,0) (3) (0,1)
Step-by-step explanation:
The slope of the line is the number times x. This equation is y=mx+b, where m is the slope and b is the y-intercept. In this case, m is 2, so we have our slope. The y-intercept is easy, as we already know it to be (0,1). The x-intercept is the point where the line hits x when y=0. To solve for the x-intercept, we set y to 0 and solve. We have 0=2x+1. First, we subtract 1 from both sides and get -1=2x. Next, to get x by itself, divide both sides by 2. Now we have -1/2=x. Now we have our x coordinate for our x-intercept. Because of this, we get (-1/2,0) as our x-intercept.
