Answer: 9
you have to multiply. f × x. substitute x as 3 shown in the question and on the x side of the tabel you will see 3 right across from it is 9 that's how I got my answer.
20y+5x≤100 divide all terms by 5
4y+x≤20 subtract x from both sides
4y≤-x+20 divide both side by 4
y≤-0.25x+5
So just in simplest terms, the slope is slightly negative and it should be shaded under the line since y is less than the line...so it is the second graph.
OK. Instead of trying to find a quick, slick, easy, short way,
let's just do it the long, sensible way. We'll find the value of
each function at x=-2 and at x=-4, then see which one changed
the most and which one changed the least.
g(x) . . . (table)
when x=-2 . . . g(x) = 0
when x=-4 . . . g(x) = -8
Amount of change . . . 8
h(x) = |2x + 3| + 7
h(-2) = |-4+3| + 7 = 1+7 = 8
h(-4) = |-8+3| + 7 = 5+7 = 12
Amount of change . . . . . . . 4
m(x) . . . (graph)
m(-2) . . . . . -10
m(-4) . . . . . less than -18
maybe -20 or -25
Amount of change . . . more than 8
maybe 10 or 15
Largest change . . . m(x)
Smallest change . . h(x)
