Answer: x = -2, -2/3
If it wrong I am sorry
Answer:
y=1/2x
Step-by-step explanation:
Slope intercept form is the most commonly used linear equation:
It goes like this:
In this equation, m is the slope and b is the y-intercept.
Your line has a slope of 1/2. So, your m-value is 1/2.
y=1/2x+b
B, your y-intercept, is at the origin.
The origin is the point (0,0).
So b, is 0 (y-intercept is the y-value when x is 0)
y=1/2x+0
=
y=1/2x
Answer:
14 months
Step-by-step explanation:
1/3 x 12 = 4.
1/3 x 2 = 2/3.
12 + 2 = 14.
