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.
Answer:
6,048
Step-by-step explanation:
l=3w
3w + 3w + w +w =96
8w =96
w=12
l= 36
12×36×14 = 6,048
Answer:
F(x)= -19
Step-by-step explanation:
Just plug in ‘-3’ for every ‘x’ in the equation.
4(-3)-7
-12-7
F(x)= -19
It is calculations because with measurements you would just put a decimal. The calculator uses improper fractions.
