how do you indicate congruent segments in a diagram? how do you indicate congruent angles in a diagram?
ICE Princess25 [194]

9514 1404 393

Answer:

  • segments: using the same number of hash marks
  • angles: using the same number of arcs, or hash marks on an arc

Step-by-step explanation:

The attached diagram shows that segments AC and BD are congruent by using a single hash mark on each of those segments. If other segments are congruent, but not congruent to these two, the "decoration" would be different, probably two hash marks. Segments marked with the same "decoration" are intended to be understood as congruent.

__

The "decoration" used for congruent angles is an arc of some kind. Here, a single arc is used to signify angle CAB is congruent to angle DBA. Additional arcs could be used for other congruent angles, or hash marks can be put on the arcs.

Given f(x) = -x + 2, find f(-1)
jarptica [38.1K]

f(x) = -x + 2

f(-1)   This means that they want you to find the value of f(x) or y when x = -1.

f(x) = -x + 2     Substitute/plug in -1 into "x" since x = -1

f(-1) = -(-1) + 2     (two negative signs cancel each other out and become positive)

f(-1) = 1 + 2

f(-1) = 3

Think about the function f(x) = 3 - 2x.<br><br> What does the notation f(0) mean?
dlinn [17]
In order to find this you have to replace any x with zero therefore we will have
3 - (2*0) => 3-0 = 3
so the answer is 3
