Answer:

Step-by-step explanation:

Let's start by prime factorizing (finding the prime factors) of 16 and 21:

$16=4*4=2*2*2*2=2^4$

$21=3*7$

We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.

1 What is the equation of the line parallel to 8x - 16y= -14 and passing through (3, 0)?

andreev551 [17]

Answer:

8x -16y = 24

Step-by-step explanation:

8x - 16y= -14

A parallel line (i.e. same slope) will be: 8x - 16y= c

We have to find the value of "c".

If it passes through (x, y) = (3, 0) ⇒ 24 - 0 = c,

so equation is 8x -16y = 24
