Answer:
Step-by-step explanation:
m=7
So by using point slope form
y-y1=m(x-x1)
y-(-2)=7(x-7)
y+2=7x-49
y-7x+51=0
The vertex is the point where the function changes direction, in this case from growing to decrease. That is the point wiht x-coordinate 4 and y-coordinate 1, so the point is (4,1).
There are two opposite pairs and I am not sure if this is a select all question.
But here are the following:
B) C and F are pairs. That is -4 and 4
D) A and H are pairs. That is -8 and 8
Hope this helps!
<em>Answer:</em>
<em>The unknown angles are 45 and 63</em>
<em>Step-by-step explanation:</em>
<em>5x + 7x + 72 = 180 (angle sum property)</em>
<em>12x + 72 = 180</em>
<em>12x = 180 - 72</em>
<em>12x = 108</em>
<em>x = 108/12</em>
<em>x = 9 </em>
<em />
<em>Therefore, 5x = 5*9 = 45</em>
<em> 7x = 7*9 = 63</em>
