Answer:
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.As we have seen in examples above, we can represent a function using a graph. Graphs display many input-output pairs in a small space. ... The most common graphs name the input value x and the output value y , and we say y is a function of x , or y=f(x) y = f ( x ) when the function is named f .
Step-by-step explanation:
Brainlist will be very accept if you want took me a while to do :)
12x15=18(3x+4)
180=54x+72
-72 -72
108=54x
/54 /54
2=x
X=2 the other person is a d0uche for answering like that so I answered instead of them
When solving a system by graphing you need to see where the lines intersect.
Below is a picture of these lines graphed. The green line is y = x +4 and the blue line is y = 4x - 1
The red dot represents the intersection is about (1, 5)
The original point is: (1.667, 5.667)
Hope this helped!
X/26=28
•26=•26 (cancels each other out)
X=728
