Here are the steps to calculating the given equation:
Distribute 2 to x and 6: 2x-12+14=38
Group like terms: 2x+(-12+14)=38
Combine like terms: 2x+2=38
Subtract number on 'x' side: 2x+2-2=38-2
Simplify: 2x=36
Divide: 2x/2=36/2
Simplify: x=18
Label with correct terms:
I cannot do this because you did not provide sufficient information, I would need to know what the difference between the two, or if 'x' stood for one particular temperature. Hope that helped enough with what you provided.
Answer:
24 is the whole desposited. unless you are not counting the money she spent to open it. then it would be $23.50
The first point could be (5, 40)
The second could be (25, 20)
That's just assuming the number of minutes are the x-coordinates...
Hope this helps!
Sine is an odd function, meaning that sin(-x)=-sin(x) ∀ x ∈ R.
=>
sin(-t)-sin(t)=-sin(t)-sin(t)=-2sin(t)=-2a
