Answer:
All angles must add up to 180, so if you add 69+5x+2+9y-3, it is = to 180.
First we can subtract 68 cancelling out 69, 2 and -3 so it is
5x+9y = 112. I assume this is an iscoceles triangle so we already knew 9y - 3 = 69, y=8, x=8
The answer is A. The line would run through the point (-6,8) and run parallel to the x -axis, tangent to the circle.
Image of A (2-8, 6+4) =(-6,10)
image of B (-1-8, 5+4)=(-9,9)
Sally paid $3.82 while Martha paid $1.82 (which makes a total of $5.64 and shows that Sally paid $2 more than Martha)
2x-10+4x-18=4x
6x-28=4x
2x=28
x=14 is the solution
6x-28=4x is equivalent
Hope this helped!
