The system of inequalities is:

y ≤ -0.05*x^2 + 6x

y >  1.5x + 45

(30, 90) is not a solution of that system, while (60, 160) is a solution.

<h3>How to get the system of inequalities?</h3>

We know that the revenue y is given by:

y ≤ -0.05x^2 + 6x

And we know that the costs are 1.5x + 45, and the revenue must be larger than that, so we also have the inequality:

y >  1.5x + 45

So the system is:

y ≤ -0.05*x^2 + 6x

y >  1.5x + 45

Now, the point (30, 90) means that we need to replace x by 30 and y by 90, replacing that in the second inequality, we will get:

90 > 1.5*30 + 45 = 90

90 > 90

This is false, so the point is not a solution of this inequality, meaning that the point is not a solution of the system.

For the second point we do the same: x= 60, y = 160, replacing that in the second inequality we get:

160 > 1.5*60 + 45 = 135

160 > 135

This is true, now we need to check with the other inequality.

160 ≤  -0.05*60^2 + 6*60 = 180

This is also true.

So the point (60, 160) is a solution to the system.

5х - у = -4 slope intercept form​
statuscvo [17]

Answer:

y = 5x + 4

Step-by-step explanation:

5x - y = -4

5x - 5x - y = -4 - 5x

-y = -5x -4

-y/-1 = -5x/-1 -4/-1

y = 5x + 4

Zoe creates a spreadsheet to make simple interest calculations. The user input values for the principal, rate, and time in years
Readme [11.4K]

Answer:

a. For A2 to compute the interest.

b. For B2 to compute the principal.

c. For C2 to compute the interest rate.

d. For D2 to compute time in years, given the interest, rate, and the principal.

e. For E2 to compute the time in months, given the time in years.

a) A2 = B2 x C2 x D2

b) B2 = A2/ (C2 x D2)

c) C2 = A2/ (B2 x D2)

d) B2 = A2/ (C2 x D2)

e) E2 = 12 x D2

I know they only asked for principle, I just added for imformation lol
