Answer:
16 1/3 lbs
Step-by-step explanation:
We can write a ratio to solve
7 lbs x lbs
-------------- = -------------
3 loaves 7 loaves
Using cross products
7 * 7 = 3x
49 = 3x
Divide each side by 3
49/3 = 3x/3
16 1/3 lbs
The rate of change of a linear equation (first degree) is equivalent to the slope of a line. Slope is described as the vertical movement (rise) of the line over its horizontal counterpart (run). In determining the rate of change or slope (m) given 1 data point (x',y'), point-slope form is applicable. Point-slope form is: (y-y') = m (x-x'). Substitute the given point (-5,-1) in the equation. By substitution, [y-(-1)] = m [x-(-5)]. Re-arranging the equation, the rate of change or slope is, m = (y+1)/(x+5).

Answer:
Step-by-step explanation:
4x - 12 ≤ 16 + 8x
4x - 8x ≤ 16 + 12
- 4x ≤ 28
<em>x ≥ - 7 or [ - 7, ∞ )</em>
