y increases by 8
given y = 4x - 3 then an increase in x of 2 units gives
y = 4(x + 2) - 3 = 4x + 8 - 3 = 4x + 5
change in y = 4x + 5 - (4x - 3) = 4x + 5 - 4x + 3 = 8
Step-by-step explanation:
I have no idea if I'm doing it right but my guess would be to take the values that we get from f(x) and g(x) when x = 1. Therefore we get that f(x) is equal to 4 and g(x) is equal to -1. We than just do f/g which is 4/-1 which gives us the final answer of -4 which is option B.
Answer: Option B, -4
A B C D E F G and L are proportional
and H I J and K are non-proportional.
D is the only viable answer among these, as A, B, and C all contain two even integers which, by definition, have a greatest common factor of 2.
<em>Correction: </em>I was incorrect in saying that <em>all </em>even integers have a greatest common factor of 2; 2 is at least guaranteed to be <em>one of the common factors </em>in any group of even numbers, but these examples all have it as their <em>greatest </em>common factor as well.
