The answer is the last option: The associative property of multiplication
N(n-1)/2
for any integer n, n to the 3rd power > 0. (-2)^2 = -2 *-2=-8
each angle in a right triangle has a different measure.
both fractions reduce to 1/3
Answer:
C
Step-by-step explanation:
Since lines a, b, c, d, and XY are all parallel to each other, and are a part of the same triangle, they are all similar. Thus, we can compare rates -- the distance between P to Y is 12, and 2/3 of 12 is 8, so we need to find that length, which is C
Graph this equation on a graphing calculator, the line crosses the x axis 3 times, those points are at -4 , 2 , and 6
to find on calc, enter equation is y=, then hit 2nd , trace , 2: zero
Answer:
A)equation=A=318-27.9·T
b)A=318-27.9·6= A=150.6 students per counselor
C)200=318-27.9·T= 4.2 Years
Step-by-step explanation:
A) A=318 students per guidance counselor, that number decreases
T= time that passed from 2009
Then the equation would be like==
A(students per counselour)= 318(Number in 2009)-27.9(Less every year)·T
b)Resolve thje equation changing T by 6---->Thats because 2015-2009=6
A=318-27.9·6= 150.6 students per counselor.
C) Resolve the equation changing A by 200
200=318-27.9·T= (200-318)÷(-27.9)== 4.2 years(T)
