answer: 3/1
Step-by-step explanation:
This is like a puzzle, and each part tells you something. The first statement tells us that x is a negative number and y is a positive number. The next statement, x + y , is what we need to know. The first absolute value gives us x. Solve for the absolute value, that is, what is inside can be either negative or positive so either x-9 = 12 or x - 9 = -12. Solve those for x = 21 or x = -3. We know that x is negative from that first statement, , so x is -3. Do the same with the other absolute value to solve for y, then add the two together to get your final answer. hope this helps a bit!

if x=degrees then the measure of the arc is
x/360=arclegnth/circumference
(if you understna that the angle's fraction out of 1 whole=arc's fraction out of circumference, you can use that info to make your own formula)
so
find circumference
c=pid
c=3.14*16
c=50.24
so
270/360=x/50.24
3/4=x/50.24
multiply both sides by (4*50.24)
150.72=4x
divide both sides by 4
39.68
round
37.7
answer is D

Sample Answer: The value of m must be greater than the value of n. When you multiply the binomials, the middle term is the result of combining the outside and inside products. So, bx = –nx + mx, or bx = (–n + m)x. This means that b = –n + m. When adding numbers with opposite signs, you subtract their absolute values, and keep the sign of the number having the larger absolute value. Since b is positive, m must have the larger absolute value.
its right ur welcome
Answer:
(m - n ) = b
mn = c
The relationship between m and n is such that their product is c and their difference is b
Step-by-step explanation:
roots are x = -m and x = n
-m = -b/2 - root(b*b + 4c)/2
n = -b/2 + root(b*b + 4c)/2
(x + m)(x -n) = x*x +(m - n)x - mn
(m - n ) = b
mn = c
