Answer:
x = 3
Step-by-step explanation:
=> 4x-5x+9=5x-9
=> -x-5x = -9-9
=> -6x = -18
=> x = 18/6
=> x = 3
In total 2/4 + 3/4 = 8/4 x 5 = 25/20 total
2/4 x 5 = 10/20 milk
3/4 x 5 = 15/20 flour
This is a linear function.
A linear function is a straight line that has a slope, and follows the formula: <em>
y = mx + b</em>
In which:
y = y
m = slope
x = x
b = y -intercept
