zubka84 [21]

Answer: $(x+2)^{2}+(y-4)^{2} =16$

and

$(x-6)^{2} +(y+4)^{2} =20$

Step-by-step explanation:

Equation for a Circle

$(x-h)^{2} +(y-k)^{2} =r^{2}$

h= -2 k= 4 r= 4

$(x+2)^{2}+(y-4)^{2} =16$

Part 2

Complete the Square

$x^{2} +y^{2} -12x+8y+32=0\\(x^{2}-12x+-)+(y^{2}+8y)=-32\\(x^{2} -12x+36)=(y^{2} +8y+16)=-32+36+16\\\\(x-6)^{2} +(y+4)^{2} =20$

Each day, a salesperson earns $25 plus 5% of their total sales for the day. The salesperson's goal is to earn more than $50 on T

Lera25 [3.4K]

The true statement about the inequality is that Total sales per day is greater than $250

<h3>How to write and solve inequality equation?</h3>

Total sales per day = x

Amount earned per day = 25 + 5% of x

= 25 + 0.05x

Thursday = 4th day of the week

The inequality:

4(25 + 0.05x) > 50

100 + 0.2x > 50

100 - 50 > 0.2x

50 > 0.2x

x > 50/0.2

x > $250
