4x/x adding 10 to each
4x+10/x+10 =2
Multiple x+10 to each side
4x+10=2x+20
Then subtract and get
2x=10
Divide
X=5
Now plug it back in

Domain : (-5, -4, -2, 0, 1)
range : (4,-1, 1,4,3)
Answer:
a
Step-by-step explanation:
Given
u = (x₁, y₁, z₁ ) and v = (x₂, y₂, z₂ ) then the dot product is
u • v = (x₁ x₂ ) + (y₁ y₂ ) + (z₁ z₂ )
Then
v • w
= (5 × 9) + (- 4 × - 2) + (4 × 7)
= 45 + 8 + 28
= 81 → a
THe problem is basically telling us: 
where P is the power disappated and V^2 is our voltage squared.
So, for the second example to find the power we simply have to plug k and our voltage back in, so:
