Answer:
the only one that is a function is B
Step-by-step explanation:
the rest of them have repeating inputs which makes them no functions
1. f = g(m1 - m2)/d2
2. f d2 = g(m1 - m2)
3. f d2/g + m1 - m2
4. f d2/g + m2 = m1
5. [Answer] m1 = f d2/g + m2
Answer:
infinitely many solutions.
Step-by-step explanation:
y=4x
y-4=4 (x-1)
Lets substitute the first equation into the second equation.
4x -4 = 4(x-1)
Distribute
4x-4 = 4x-4
Subtract 4x from each side
4x-4x-4 =4x-4x-4
-4=-4
This is always true. X can be anything. We have infinite solutions
On a calculator of you put in 1/4 it would give you 0.25 or simply .25
Sure... a good example of that is when you have non-linear expressions in the system, like say for example a linear and a quadratic, like y = 4x and y = x².
recall that for a system of equations, where the graph of both equations intersect, is the solutions, check the picture below.
