Answer:
(a) |-9| ≠ |9| is NOT TRUE.
(b) is TRUE
(c) -7 ≤ -5 is TRUE
(d) |-1| ≥ 0 is TRUE.
Step-by-step explanation:
Solving each expression separably:
(a) |-9| ≠ |9|
By the definition of <u>MODULUS FUNCTION</u>: IxI = x, if x > 0
= (-x) if x <, 0
⇒ I-9I = -(-9) = 9, and I9I = 9
So, I-9I = I9I . Hence, |-9| ≠ |9| is NOT TRUE.
(b)
⇒
and (-8) < 3.
Hence, is TRUE
(c) -7 ≤ -5
-7 < -5 on the number line of integers.
Hence, -7 ≤ -5 is TRUE
(d) |-1| ≥ 0
I(-1)I = -(-1) = 1
and 1 > 0
Hence, |-1| ≥ 0 is TRUE.
Answer:
each circle weight 3 grams
Step-by-step explanation:
I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo,
<em>This hanger is in balance. There are two labeled weights of 8 grams and 20 grams.The four circles each have the same weight.</em>
<em>what is the weight of each circle.</em>
My answer:
Let x is the the weight of the circle
Because this hanger is in balance, so we can form the equation:
20 = 8 + 4x
<=> 4x = 20-8
<=> 4x = 12
<=> x = 3
So each circle weight 3 grams
