Hello I have a math meeting at 10 (less than an hour) and I need your help answering these questions! I will give 20 pts Describe a real-world situation in which opposite quantities combine to make zero.
What are the associative and commutative properties?
How can the associative, commutative and additive inverse properties be useful when adding and subtracting rational numbers? Use the equation below to demonstrate these properties: $25.00 -$15.00 -$37.00 +$ 50.00= balance in bank account

c. 6tan80

step-by-step explanation:

see below

step-by-step explanation:

x+2> 6

subtract 2 from each side

x+2-2 > 6-2

x > 4

there is an open circle at 4 since is it is greater than and the line goes to the right

yes.. it's proven to be 36.

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
