All of them are statistical
2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3
Answer:
2 x 10^1 (it looks weird how i typed it so its the first answer btw)
Step-by-step explanation:
(6.4 x 10^3) / (3.2 x 10^2) 1. Follow PEMDAS
(6400) / (320) 2. Divide regularly
20 3. Take the 20 and put it in scientific notation
2 x 10^1
hope this helps :)
Answer:
Step-by-step explanation:
4/5
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.
