r = 1/21
Answer:
Micheal = Kevin - 334mm
Kevin > Ben > Micheal
so you add smthing less than 334mm to Micheal's distance that is not a negative number
Answer:
1. 
2. 
3. Domain: 0≤x≤7
Range: 0≤y≤12
Step-by-step explanation:
1. Assuming 1 unit = 1 box on the grid, therefore, coordinates of C and D would be:
C(0, 0),
D(7, 12)

2. Equation of the using the slope-intercept formula,
, where,

b = y-intercept, which is where the line CD cuts the y-axis = 0
Plug in the values for m and b into the formula to get the equation of the line:


3. The domain for C to D part = all x-values = 0≤x≤7
The range = all y-values = 0≤y≤12
Answer:
Step-by-step explanation:
1.5(x + 4) - 3 = 4.5(x - 2)
1.5x + 6 - 3 = 4.5x - 9
1.5x + 3 = 4.5x - 9
3 + 9 = 4.5x - 1.5x
12 = 3x
12/3 = x
4 = x <======
