Answer:
$4.99
Step-by-step explanation:
20 - 5.03 = 14.97
14.97 ÷ 3 = 4.99
Step-by-step explanation:
The given equation is :
2x+7y=11
We need to tell the point (-5,3) lies on the graph of the above equation of not.
Put x = -5 and y = 3 in the LHS of the above equation.
LHS = 2x+7y
= 2(-5)+7(3)
= -10 +21
= 11
It means, when we put x = -5 and y = 3 in the above equation, we get 11. Hence, (-5,3) lies on the graph of the equation.
A counter example disproves a statement.
