A.
pb=4x+2+7x+7+5x-4
pb=16x+5
pp=x+3+x+7+2x-5
pp=4x+5
B.
pb-pp=16x+5-(4x+5)
pb-pp=16x+5-4x-5
pb-pp=12x
C.
pb(3)=16*3+5=53
pp(3)=4*3+5=17
Answer:
(-∞,+∞)
Step-by-step explanation:
Because the equation does not have the y in a denominator, there should be an infinite number of solutions for the range.
