Answer:
z = -166
Step-by-step explanation:
1. Subtract 3 from both sides to get z/2 = -83
2. Multiply 2 by both sides to get z = -166
z = -166
Answer: -1
-2-3-(-4)
-5-(-4)
-1
3. Answer: y = 4
<u>Step-by-step explanation:</u>
Need to find the slope (m):


= 
= 0
Now input ONE of the points (1, 4) and the slope (m = 0) into the Point-Slope formula:
y - y₁ = m(x - x₁)
y - 4 = 0(x - 1)
y - 4 = 0
y = 4

4. Answer: 
<u>Step-by-step explanation:</u>





Desmos is a graphing calculator just put in your equation and it will show you the graph for it
The lower end of the range is
42.670 - 0.002 = 42.668 mm
The upper end of the range is
42.670 + 0.002 = 42.672 mm
The range of acceptable values is 42.668 mm to 42.672 mm.
