Substitute w = 1 and w = 3 to determine if the two expressions are equivalent
Effectus [21]

Answer:

Expressions are not equivalent

Step-by-step explanation:

Given expressions are:

4(3w+4)\ and\ 16w+12

Putting w=1 in both expressions

4(3w+4)\\=4[3(1)+4]\\=4(3+4)\\=4(7)\\=28\\\\16w+12\\=16(1)+12\\=16+12\\=28

Both expression have value 28 on w=1

Putting w=3 in both expressions

4(3w+4)\\=4[3(3)+4]\\=4(9+4)\\=4(13)\\=52\\\\16w+12\\=16(3)+12\\=48+12\\=60

Both expression have different values at w=3

Hence, in order for the expressions to be equivalent they both should produce same value on w=3 too.

So, it can be concluded that both expressions are not equivalent ..

G = {(1, 1), (1, 2), (1, 3), (1, 4)} Is G a function and why? Yes, no two ordered pairs in this list has the same second element
inna [77]

Answer:

No, each ordered pair in this list has the same first element.

Step-by-step explanation:

An input can only have 1 output, but multiple inputs can have the same output. How you can check this if you have a graph is if you can draw a straight line (top to bottom) anywhere on the graph and it intersects with the line once or not at all.
