Answer:
A) y>=-1
Step-by-step explanation:
The line itself is y=-1, but it is also filled in. Therefore, we are down to either A or C as the right answer
Since (0,0) is a solution to the inequality as indicated by the shade, we know that since y=0 in the origin, 0 is greater than -1, so therefore A is the correct answer.

Answer:
1:25 (dm:km)
Step-by-step explanation:
For the ratio, you compare two units.
Naturally, we could say that 2 dm corresponds to 50 km
Written in fraction form:
2dm/50km
Simply the fraction normally:
1dm/25km
Just replace the "/" with ":"
1:25 (dm:km)
1) 2x+1x= 63
2) 3x= 63
3) 3x/3= 63/3
4) x= 21
5) 2(21)+1(21)=63
6) 42+21= 63
The 2 groups would be 42 to 21.
