aliya0001 [1]
The answer 
<span>2x - y + z = -3          (1)
2x + 2y + 3z = 2       (2)
3x - 3y - z = -4          (3)

</span> (1) - (2)              3y +2z =5
 3 .(1) - 2.(2)       3y+5z = -1<span>

let 's solve 
</span>3y +2z =5
3y+5z = -1<span>
z= - 2, and 3y =5+4=9,  y=3, so  </span>2x - 3 -2 = -3 implies x= 1
<span>
finally x=1, y=3 and z= -2
proof 
</span>2x - y + z = -3??     2.1 - 3 -2 = -3  (true)<span>

Answer:

<h3>              a. the  vertex represents a minimum point</h3><h3>              b.  f(x) = (x + 5)² - 5</h3>

Step-by-step explanation:

a.

a = 1 > 0  ← that means the parabola opens up, so the vertex is minimum of the function

b.

  f(x)=x^2+10x+20\\\\f(x)=\underline{x^2+10x+25} - 25+20\\\\f(x)=(x+5)^2-5
