Answer: B) -48
Step-by-step explanation:
If the system of two linear equations 
has infinitely many solutions , then
For the given system of linear equations : 
We , will have
The value of 
Hence, the value of rs is -48.
Thus , the correct option is B) -48.
-18 +30s -72t +12u is the answer
Answer:
x = 81
Steps:
It says that y ~ √x
We have points (9, 18) as a guide.
We can write y = f(x) = a√x +b
Use points (9, 18) as a guide
18 = a√9 +b
18 = 3a + b
One solution might be a = 6, which means f(x) = 6√x
Thus when y = 54,
54 = 6√x
9 = √x
81 = x
Answer:
20
Step-by-step explanation:
the number line is patterned in twos, so the dot will be at 20, since its 4 spaces away from 12
