The horizontal compression of a graph means that the graph has come closer to the y-axis. Horizontal stretching and compression occur when a factor is multiplied to the original equation. If the factor being multiplied is greater than 1, then the graph is compressed. If the factor being multiplied is less than 1, the graph is stretched. Therefore, in this case, a number greater than 1 must be multiplied to -x + 5.
The answer is B. F(x) = -2(x-5)
<h2><em><u>negative relationship and not a causal relationship</u></em></h2>
1 / (1/6) = x / (2/3)...1 drop to 1/6 dash = x drops to 2/3 dash
cross multiply
(1/6)(x) = (1)(2/3)
1/6x = 2/3
x = 2/3 * 6
x = 12/3 = 4 drops <==
We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.
A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles
