Replace all the x values with -3
f(-3)=-2(-3)^2+5(-3)
f(-3)=2(9)-15
f(-3)=18-15
f(-3)=3
Hope I helped :)

Answer:
(y+15) = 4/5(x+5)
Step-by-step explanation:
slope = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5
(y+15) = 4/5(x+5)
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.

Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.

Answer:
Hello,
sin y=4/20=1/5
==> y=11,5369590...°
