Answer:
X<7. Graph 7. Then put a open circle and arrow it going left! And there you go.
Step-by-step explanation:
Add 18 to both sides. Since -2x has a negative, you flip the sign to less than instead of greater than.
2nd answer.
any pts in the shaded region satisfies your simultaneous equation.
Answer:
a. has one solution
b. infinite solution
Step-by-step explanation:
a.
2(x - 1) + 6 = 4x - 22
2x - 2 + 6 = 4x - 22
2x - 4x = 2 - 6 - 22
-2x = -26
x = 26/2
x = 13
b.
6(2x + 1) – 2 = 12x + 4
12x + 6 - 2 = 12x + 4
12x - 12x = 4 + 2 - 6
0 = 0
Answer:
Here you go - IM NOT 100% SURE THESE ARE RIGHT
Step-by-step explanation:
1. 2 complex solutions
2. 1 complex solution
3. 1 complex solution
4. no complex solutions
a) n (No. of peoples) = 50
r (No. of prizes) = 3
p(n,r) = p (50,3)

b) n(No. of players)=14
r (No. of players for Batting)=9

c)n(Total applicants)=30
r(tester positions)=4
