Since prime numbers only have two factors (itself and 1) then it would have to be the same number. So it would be the number besides one. Ex. Prime number: 7, the GCF would be 7 if it was compared with itself.
Step-by-step explanation:
Y=9
Replace y in the equation:x+9=3
X=9-3=6
So it's D(6,9)
Cost=$200
sales tax rate, r= 8%
tax=cost*r=$200*0.08=$16
total cost = cost+tax=$200+$16=$216
Answer:
answer is the ratios are not equivalent or not in proportion
Step-by-step explanation:
you can find it by crops multiplication
4/7
8/11
4*11
8*7
44=56
Therefore it is not in proportion
Answer:
16
Step-by-step explanation:
f(x) = 2x² when x>4
We cannot use this expression of f to calculate f(4)
because ,this expression define f for the value of x
that are greater (not equal) than 4.
………………………………………………………
f(x) = 4x when x ≤ 4 , here x is can be equal to 4
(notice the sign ≤ )
Therefore
f(4) = 4 × (4) = 16
