Answer:
The ordered pair is (2,3)
Step-by-step explanation:
we know that
If a system of equations has infinite solutions, then the equations are the same
we have
3ax+3y=5b -----> equation A
2x+y=5 ----> equation B
Multiply equation B by 3 both sides
3*(2x+y)=5*3
6x+3y=15 -----> equation C
Compare equation A and equation C
so
3ax=6x------> 3a=6 -----> a=2
5b=15 ------> b=3
The ordered pair is (2,3)
I think its 15+y or 15y im not surw
Answer:
r≥2.5
it can't be < because the green dot is filled in
r is larger than 2.5 because the arrow goes to the right
