Answer:
Um Yes i dont know how but -5 is not a lot and then it addition so Yes will be my answer to this. mY Opinion
Answer: D
Step-by-step explanation:
You should use <span>Pythagorean theorem
A^2+B^2=C^2
8^2+5^2=C^2
64+25= C^2
89=C^2
C=9.4333 Mi
The answer is B</span>
5 - v < 6, 5 - v >= 0
-5 + v < 6, 5 - v < 0
1) - v < 6 -5 (move 5 to the right side and then multiply by -1 both sides of the inequality)
v > -1 (don't forget that here v <= 5)
2) v < 6 + 5 (move -5 to the right side)
v < 11 (here v should be more than 5)
so from 1) you get that v is from -1 to 5 inclusive (-1;5]
and from 2) you get that v is from 5 to 11 (5;11)
so by adding up results from 1) and 2) you get v is (-1; 11)
answer: (-1; 11)
Part A: -x+y=5
+x +x
y=x+5
4x+x+5=10
5x+5=10
-5 -5
5x=5
x=1
1(-x) +y=5
-1+y=5
+1 +1
y=6
The solution is (1,6)
Part B:
-x+y=5
-1+6=5
5=5
4x+y=10
4(1)+6=10
4+6=10
10=10
