The correct answer is h = 9 and k = -8.
While this may seem like a much more complicated problem, the fact is that the vertex of the equation is aways expressed in terms of (h, k). So, since this vertex is already given, we know that the values are simply the values of h and k are simply the x and y values of the vertex. No math is really needed to solve this.
The greatest common factor of 22 and 99 would be 11. :)
Substitute y = 3x + 15 to the equation -4x + 7y = 20:
-4x + 7(3x + 15) = 20 <em>use distributive property</em>
-4x + (7)(3x) + (7)(15) = 20
-4x + 21x + 105 = 20 <em>subtract 105 from both sides</em>
17x = -85 <em>divide both sides by 17</em>
x = -5
Substitute the value of x to the equation y = 3x + 15:
y = 3(-5) + 15
y = -15 + 15
y = 0
<h3>Answer: x = -5 and y = 0</h3>
