Answer:
To find a slope perpendicular to another line, you need to change the sign and flip the fraction.
Your answer:
m = -2/3
Answer:
Step-by-step explanation:
The definition of a function f from A to B, regardless to injectivity or surjectivity, is that the domain of f is A, in its entirety.
This means that if f:A→B, then for every a∈A, there is a unique b∈B such that the pair (a,b)∈f.
So the converse holds just for it to be a function from A to B.
Answer:
12.5%
Step-by-step explanation:
8+4+4=16
2/16*100=12.5
12.5%
Step-by-step explanation:
1/a + 1/b + 1/c = 1/(a+b+c)
=> 1/a + 1/b = 1/(a+b+c) -1/c
=> (b+a)/ab = {c - (a+b+c)/c(a+b+c)
=> (a+b)/ab = -(a+b)/(ac+bc+c^2)
=> 1/ab = -1/(ac+bc+c^2)
=> -ab = ac+bc+c^2
=-c^2 = ab+bc+ca
Similarly we can show that
-b^2 =ab+bc+ca and -c^2 = ab+bc+ca
So a=b=c. since -a^2 = -b^2 = - c^2
Then 1/a + 1/b + 1/c = 1/(a+b+c) => 3/a= 1/3a
=> 1/a^5 + 1/b^5 + 1/c^5 =3/a^5=(( 3/a )(1/a^4)
= 1/3a × 1/a^4 = 1/3a^5 = 1/(a^5 +b^5+c^^5)

The measure of x is 100 degrees.
Explanation: a line is 180 degrees and we remove 80 from it because that’s the angle GFH, 180-80= 100 degrees
