Locate 1 on the x axis. This is the horizontal number line.
Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.
Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.
If the input it is x = 1, then the output is y = -4
So that's why the answer is choice A
Answer:
this is not an answer sorry, but someone answered me with a link and I opened it and it virused my phone
X−7<1
Add 7 to both sides.
x−7+7<1+7
x<8
To plot this on a number line, put a circle around 8 and a line going to the left with an arrow at the end.
Answer:
so I think your trying to find what c is right
if that so.that will be 90° that is an right angle all right angles are 90° I might be wrong because I'm not sure on what your trying to find but I hope I helped just a Little bit
