1, 2, 3, 4, 5 idk i need some sets to be able to answer
<span />
I assume you mean these as fractions, which in that case it is A
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b / *(-1)
13 = k * 8 + b
---------------------
-11 = - k * 7 - b
13 = k * 8 + b
----------------------
2 = k
13 = 16 + b
b = 13 - 16 = -3
y = 2 x - 3 ( y varies directly with x )
Answer:
12.5
Step-by-step explanation:
25/8 x 8/5 x 5/2 simplify 25 by 5
5/8 x 8/1 x 5/2 simplify 8 by 8
5/1 x 1/1 x 5/2
5 x 1 x 5/2
5 x 5/2
25/2
12.5
