statements
case a) The domain is {x|x ≤ –2}-------> Is False
the domain is all real numbers---------> the interval (-∞,∞)
case b) The range is {y|y ≤ 6}.------> Is True
The range is the interval (-∞,6]
case c) The function is increasing over the interval (–∞ , –2).-----> Is True
See the attached figure
case d)The function is decreasing over the interval (−4, ∞).-----> Is False
In the interval (-4,-2) the function is increasing and in the interval (-2,∞) the function is decreasing (See the attached figure)
case e)The function has a positive y-intercept.------> Is True
The value of y-intercept is

Answer: It costs $1.22 to make each paperweight.
Step-by-step explanation:
Given : Selling price of 95 identical paperweights = $230.85
Then, Selling price of 1 paperweight = (Selling price of 95 identical paperweights) ÷ 95
= $ (230.85 ÷ 95) = $ 2.43
Now, selling price of each paperweight = 2 x ( cost of each paperweight)
⇒ cost of each paperweight = (selling price of each paperweight ) ÷ 2
⇒ cost of each paperweight = $ 2.43 ÷ 2 = $ 1.215 ≈ $ 1.22
Hence, it costs $1.22 to make each paperweight.
Answer:
z = 10
Step-by-step explanation:
the steps have been attached above
To form a linear pair means that when added, they equal 180 degrees.
but if they have equal measures....180/2 = 90...then they would both equal 90 degrees.....and 90 degrees is a right angle.
So ABC and CBD are both right angles
