Answer:</h2>
First: info on point-slope form.
- Formula: <em>y - y₁ = m(x - x₁)</em>
We need to find the slope of the line first.
Slope: 
Now we can complete the point-slope equation of the line.
*These equations are equivalent.
The product is
(-d)^2 -4^2 = d^2 -16 . . . . . corresponds to the 2nd selection
I think it’s E... because the first one was controlled and the second one is just observing the people that used it and the people that didn’t
Answer:
4) is the opposite function of 3), and vice versa. Because f(x) =2x-1 and its opposite f(x)=-2x+1. And we can see them both in pictures 3 and 4.
Step-by-step explanation:
A piecewise function is a function defined in a sequence of intervals. The most known piecewise function is the modular function. (1st picture)
An opposite function is given by f(x)=-x of f(x)=x
The following pictures describe the following functions:
1) f(x)=-|2x|+2
2) f(x)= 2.34x-2.34 and f(x)= -2.34x-2.34
Notice how the second function express the opposite line, by the opposite angular coefficient.
3) f(x) =2x-1 and f(x)=-2x+1
4) f(x) = -2x+1 and f(x)=2x-1
Different intervals but the same functions are graphed in 3 and 4. So the graph of f(x)=2x-1 and its opposite f(x)=-2x-1
Answer:
AB = 3√5
Explanation: You can use
a^2 + b^2 = c^2 formula.
6^2 + b^2 = 9^2.
36 + b^2 = 81.
81 - 36 = 45
√45 = 3√5
