Given that angle ABC=70° and that angle BCD=110°. Is it possible (consider all cases) that Line AB is parallel to line CD ?

no

Step-by-step explanation:

Since ∠ABC=70 and ∠BCD=110, BC is common line

AB can't be parallel to CD as ∠ABC≠∠BCD

the answer is no

60 for the first and 130 for the second

step-by-step explanation:

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
