Step-by-step explanation:
Answer:
B
Step-by-step explanation:
y≥-2x-2
put x=0,y=0
0≥-2
which is true.
so (0,0) lies on it.
graph is a solid line.
so B satisfies it.

2.25
Step-by-step explanation: Replace the z with the value given (-18) and then multiply that by 1.1 you can then add it to 21.3 and then do the exponent
Answer:
The solution of the given equations are (3,2).
Step-by-step explanation:
Given equations are :
3d−e=7 ...(1)
d+e=5 ...(2)
Add equations (1) and (2) we get :
3d-e+d+e=7+5
4d = 12
d = 3
Put the value of d in equation (2).
3+e=5
e = 2
So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).
