Explain what the graph of the function represents. Be sure to use complete sentences. f(x) = -2/3 + 490.

parallel functions.

lines negative.

functions different in that they do not have the same y-intercept or x-intercept.

Step-by-step explanation:

1.   y = -⅔x + 490    

2.   I would start with the y-intercept(490) on the graph. Then from that point, I would use rise/run to find the next point: I would go down two points (because the slope is negative), and run three points to the right.

3.   f(x) = -⅔ + 490. The graph represents the total profits of last month.

4.   View file below.

5.   The graphs of these functions are similar in the fact that they are parallel to each other, therefore having the same slope.Both lines are also negative. They are different in that they do not have the same y-intercept or x-intercept.  

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
