Determine whether the point is on the graph of the equation 2x+3y=8.<br> (1,2)
geniusboy [140]

The point (1,2) is on the graph of the equation.

Explanation:

The equation is 2x+3y=8

We need to determine the point (1,2) is on the graph.

To determine the point (1,2) 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 (1,2) in the equation 2x+3y=8, we get,

2(1)+3(2)=8

Multiplying the terms within the bracket, we have,

2+6=8

Adding the LHS, we have,

8=8

Thus, both sides of the equation are equal.

Hence, the point (1,2) is on the graph of the equation 2x+3y=8

Gias gross annual salary is 46,392. what is the recommended maximum monthly rent she should pay?
jeyben [28]
The maximum monthly rent that she should pay is 2,784.
Solution:
1,082 x 12 months = 12,984
1,648 x 12 months = 19,776
1,933 x 12 months = 23,196
2,784 x 12 months = 33,408

Since her annual salary is 46,392, she can still afford to pay the rent for 2,784 per month, which equals to 33,408 annually.
