Y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.
X+y=29.8
Y=29.8-x so
1.45x+1.55(29.8-x)=20 then solve for x
1.45x+46.19-1.55x=20
-0.1x=20-46.19
-0.1x=−26.19
X=26.19/0.1
X=261.9
Y=29.8-261.9
Y=−232
Answer:
30%
Step-by-step explanation:
15/(15+18+17) = 15/50 = 0.3 = 30%
Coordinate of point Z is 8. That is because the distance from point X to point Y is 3-(-2)=3+2=5, and same is from point X to point Z: 3+5=8. So the answer is Z=8.
