The problem is basically asking you _ x 4 = 50, so, what is 1/4 of 50? (12.5)
Dr black is standing 13 feet from a streetlamp. The lamp is making his shadow 9 feet long. He estimates that the angle of elevation from the tip of his shadow to the top of the streetlamp is 50° to the nearest foot the streetlamp is about 26 feet tall.
I hope this helps!
Y = 5x - 2
9y = -2x + 10
9y = 3x + 8
y = (3/9)x + 8/9
F(-2) = 4x(-2) = -8;
g(f(-1))= g(-8) = 2x(-8) -1 = -16 - 1 = -17.
