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.

Answer:
9 large apartments in B
Step-by-step explanation:
Same ratio
Building A = 12 small : 6 large
= 2 : 1
Building B = 18 small : x large
= 2 : 1
18/x = 2/ 1
18 = 2x
9 = x
Large apartments in B = 9
Is think your answer is x=y+5
Step-by-step explanation:
Area is 10pi I think Bc radius is radical 10 Bc 2 radical 10/2 is radical 10. Then we do pi times radical 10 to the second power. Radical 10 to the second power is 10 Bc we remove radical when it is to the second power. Therefore, it becomes 10 times pi or 10pi
