Answer:
(2,5)

Explanation:
The solution of the system is the order pair that satisfies both equations.
The first given equation is:
x = y - 3
This can be written as:
y = x+3 .......> I

The second given equation is:
x^2 - 6x + 13 = y .........> II

Substitute with I in II and solve for x as follows:
x^2 - 6x + 13 = y
x^2 - 6x + 13 = x + 3
x^2 - 6x + 13 - x - 3 = 0
x^2 - 7x + 10 = 0
(x-5)(x-2) = 0
either x = 5
or x = 2

Substitute with x in equation I to get y as follows:
at x = 5 : y = 5+3 = 8...> first solution is (5,8)
at x = 2 : y = 2+3 = 5...> second solution is (2,5)

(2, 5) and (5, 8) are the solutions to the system of equations.

We have y=x^2-6x+13 and x=3-y. 

Let's substitute x+3 for y in y=x^2-6x+13. We get (x+3)=x^2-6x+13. Now, factor to solve for x.

0=x^2-7x+10  \\ 0=(x-5)(x-2) \\ x = 2, \ x = 5

Now, substitute each value of x into one of the original equations to solve for y. 

y-3=2  \\ y = 5

y-3=5  \\ y=8
(2,5),(5,8)

  • <em>Answer:</em>

<em>1172. 08 in²</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

<em>A(prism) = 2(lw + lh + wh) - Ab(cylinder)</em>

<em>= 2(16*11 + 16*11 + 11*11) - πr²</em>

<em>= 2(176 + 176 + 121) - 3.14*16</em>

<em>= 2*473 - 50.4</em>

<em>= 946 - 50.24</em>

<em>= 895.76 in²</em>

<em>A(cylinder) = πr² + 2πr*h</em>

<em>= 3.14*16 + 2*3.14*4*9</em>

<em>= 50.24 + 226.08</em>

<em>= 276.32 in²</em>

<em>A(total) = 895.76in² + 276.32in² = 1172.08 in²</em>

<em>Good luck !</em>
