Pls Answer Quickly and if you know. Will Give Brainliest!! A deli owner has determined that his revenue, y, from selling sandwiches each day is at most -0.05x^2+6x , where x represents the number of sandwiches he sells. To make a profit, his revenue must be greater than his costs, represented by the expression 1.5x+45.

Write a system of inequalities to represent the values of x and y where the deli owner makes a profit. Then complete the statements.
The point (30,90) is of this system.
The point (60,160) is of this system.

First Blank Choices:
a nonviable solution
not a solution
both a viable and a nonviable solution
a viable solution

Second Blank Choices:
both a viable and a nonviable solution
a viable solution
not a solution
a nonviable solution

First blank: non-viable solution because the costs aren't less than the revenue

Second blank: viable solution because the costs are less than the revenue

Step-by-step explanation:

First: Insert the x into the equation and work it out to see if it is less than the y.

(30,90)  x=30 y=90

y=1.5(30)+45

y=45+45

y=90  

Non-Viable

Second: Insert the x into the equation and work it out to see if it is less than the y.

(60,160) x=60 y=160

y=1.5(60)+45

y=90+45

y=135

Viable

(hope this helps :P)

the first blank is not a solution. The second blank is a viable solution.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
