Answer:
Step-by-step explanation:
Think of the ">" as an equal sign. So, y=-4x+1. You need to plot the y-intercept, which is (0,1). Go down 4 and to the right 1. Plot the point. Keep doing this. If you want to do it the opposite way, go up 4 and to the left right.
The radius going through the tangent point is perpendicular to the tangent line, so ΔQRT is a right triangle.
QT²=QR²+RT²
QR and QS are both radii, so QR=QS=15
QT²=15²+36²
QT=39
They marked it up to 2979 since 993*3(aka 200%). You then multiply 2979 by 1.14 to get the total of $3396.06
