Answer:
D) 2/3 x - 8
E) -4x + 11
Step-by-step explanation:
y ∈ R | -∞ < y < ∞ just means that the range for y is all real numbers in a function. For y to be all real numbers, the function, when graphed, has to have no top or bottom limit. The only graphs without top or bottom limits are D and E.
A has a bottom limit
B has a bottom limit
C has a top limit

Step-by-step explanation:
Perimeter of the given triangular above = sum of all its sides.

Collect like terms


If Bob creates a new triangle that is 7 less than twice of the perimeter of the triangle above, the expression of the new triangle would be:

Simplify


New perimeter =

Let's name all the purchases "x"
so 

of them were stuffed animals, and out of that 

 were bears. 
to get the results we have to multiply the fraction of bears by the fraction of the stuff animals: 

.  
and now we simplify: 

=

and this is the answer!
