Answer:
Step-by-step explanation
I get the same answer you do, but I'm not at all certain I'm correct. I would have done it just as you did letting each y value define the new x value and then putting the - on the left in at the very end.
f(1) = 3
f(3) = -1
f(-1) = 7
But there is a minus in front of the left most f. That would make it - 7

x = - k/ rh-a

Answer:
22 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here sum = 3600° , then
180° (n - 2) = 3600° ( divide both sides by 180° )
n - 2 = 20 ( add 2 to both sides )
n = 22
Answer:
Step-by-step explanation:
Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> <u>3 3/17</u>
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
<u>y= 14.25</u>
Answer:
54 square units
Step-by-step explanation:
144 - 18 - 4(18) = 54 square units
