X=6 if you need an explanation commu
M<APB + m<BPC = 90 complementary angles
m<FPB + m<BPC = 180 linear pair
m<APB = m<EPD vertical angles
m<FPD = m<APC right angles are congruent
m<EPC + m<EPF = 180 linear pair
m<BPC = m<EPD vertical angles
Not always. Here's a statement that proves it wrong. 2 and 4 are a factor of 12. However, 8 is not a factor of twelve. In some cases though, it's right. 2 and 4 are a factor of 32. So is 8. So George is incorrect, it can only happen sometimes. Hope this helps.
It already is rounded to the nearest tenth...
F(-1) = 3
How did I figure this out?
f(-1) is substituted for f(x) so you must look at -1 on the x axis.
Once you've located -1 on the x-axis, locate what it equals to answer the question.
The answer should be the y-axis number that corresponds to -1 which is 3.
