The first inequality given is:
5x - 11 < -11
5x < -11 + 11
5x < 0
x < 0
This means that : x ∈ ]-∞,0[
The second inequality given is:
<span>4x + 2 > 14
</span>4x > 14-2
4x > 12
x > 3
This means that:
x ∈ ]3,∞[
Since the two inequalities are linked by an "or", this means that the solution is the union of the two intervals:
x ∈ ]-∞,0[ U ]3,∞[
This is going to be hard but I'll try to figure it out may take a while
P(x,y) = P'(y,x)
It interchanges the x- and y-coordinates.
Unknown but if u know lmk
She can draw a triangle and then write the lenghts of the triangles with the same numbers
