Answer:
y = 40 x = 80
Step-by-step explanation:
520 = 3.25x + 6.5y and x+y=120
x+y=120
x = 120-y
520 = 3.25(120-y)+6.5y
520 = 390-3.25y+6.5y
520 = 390+3.25y
130=3.25y
40 = y
x = 120-y
x = 120-(40)
x = 80
here's a graph
The point is on the graph of the equation.
Explanation:
The equation is
We need to determine the point is on the graph.
To determine the point is on the graph, we need to substitute the point in the equation and find whether the LHS is equal to RHS.
Thus, substituting the point in the equation
, we get,
Multiplying the terms within the bracket, we have,
Adding the LHS, we have,
Thus, both sides of the equation are equal.
Hence, the point is on the graph of the equation
