Answer:
not a function
Step-by-step explanation:
When a left-side point originates more than 1 arrow, the relation is not a function. There are two such points here, so this relation is not a function.
Answer:
1. gcd(77,30)=1

Since 1 is the last non zero remainder appearing in these equations then, 1 is the gcd of 77 and 30.
2. u=-11, v=18
Using the Euclidean Algorithm we have that

Now, we express the remainder as linear combinations of 49 and 30.

Then 
3. x=18
If
then
for some
.
Then, if k=7,

Answer:Step-by-step explanation:
All. They all add up to 40.
Answer:
x<-5 . All you have to do is pemdas which is parentheses,exponents, multiplication, division, addition and subtraction

by making r the subject, you need to divide the whole equation by 2πh
s/2πh = 2πhr/2πh
cancel out
r = s/2πh
