Answer 3

Recall what the graph a line is first,\[y=mx+b\]so first you need to put the function you have in that form, remembering the inequality, now also remember, that when you divide or multiply by a negative number, that you need to flip the inequality sign the other way, so for instance\[-2x \ge 10\rightarrow x \le -5\]so solve for y like that and tell me what you get

Answer 4

i put B as the answer already, im not sure if im going to get it right

Answer 5

That is indeed correct, i just hope that you understand why

Answer 6

yes thank you, you are very helpful

Answer 7

could you help with one more?

Answer 8

@Embryo

Answer 9

sure

Answer 10

im guessing B

Answer 11

nope nope, so to answer this, you need to know what the general equation of absolute value is\[y=\left| x-h \right|+k\]so in this, h means how far to the right you go, and k is how far up you go, the trick here, is that you look at your graph, find where the vertex is, in this case, your vertex is (5,5), so what you plug into that general formula is k=5, and h=5\[(h,k)=(5,5)\]

Answer 12

So would it have been C?

Answer 13

not quite yet, you also need to look at the inequality, since your're shading in everything that is under the graph, the inequality should be less than or equal to\[y \le \left| x-h \right|+k\]try plugging in the values i showed you earlier, the vertex of your graph, which was\[(5,5)=(h,k)\]and remember to keep the subtraction between the x and h

Answer 14

well i got it wrong already, i dont really need to figure out the answer anymore :/ lol
but thank you!
