Step-by-step explanation:
<u>Step 1: Define</u>
d(x) = 5x - 12
d(-4) is x = -4
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: d(-4) = 5(-4) - 12
- Multiply: d(-4) = -20 - 12
- Subtract: d(-4) = -32

Answer:
well its a whole
diameter is all the way across so take 8.5 and times it by 3.14 which is 26.69 that is your volume but if you want a more mathematical answer then
1 inch = 2.54 cm
16 oz = 1 lb
28.3 g = 1 oz
volume of a sphere = 4/3pi(r)^3
Step-by-step explanation:
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
m = (-5 - 3)/(-14 + 2)
m = -8/-12
m = 2/3
Slope = 2/3
