Is (1, 3) a solution to this system of equations? x + 18y = 1 5x + 4y = 17

No

Step-by-step explanation:

18(3)=54+1=55 then 15(1)=15+12=27 so nothing would be equal making (1,3) not a solution.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
