Answer:
x=9, y=10. (9, 10). The two numbers are 9 and 10.
Step-by-step explanation:
3x+5y=77
x+y=19
------------------
3x+5y=77
-3(x+y)=-3(19)
---------------------
3x+5y=77
-3x-3y=-57
-------------------
2y=20
y=20/2
y=10
x+10=19
x=19-10
x=9

Here we know that an internet service provider is implementing a new program based on the number of connected devices in each household. Currently, customers are charged a flat rate of $175 per month. Assuming just a month, we can write a constant equation given by the form:
The new plan would charge a flat rate of $94 plus an additional $4.50 per device connected to the network. So the linear equation is:
So we need to find the number of devices, x, for which the cost of the new plan is less than the cost of the current plan. By using inequalities:
<em>So you should connect less than 18 devices in a month in order for the cost of the new plan to be less than the cost of the current plan.</em>
