Answer:
Step-by-step explanation:
(3,1) lies below the vertex, so the parabola opens downwards.
Equation for a down-opening parabola with vertex (2,3):
y = a(x-2)² + 3, a<0
Plug in (3,1) and solve for a:
1 = a1² + 3
a = -2
y = -2(x-2)² + 3
Answer:
C. 3x + 5 = 2x -6
Step-by-step explanation:
Answer:
-3x+42+9x=6x+42
0x=0
x=0
Step-by-step explanation:
there is no solution
The answer is A. 21.6 just add, 9.2+0.5+6+5.9=21.6
I hope this helps!
The equation would be ' y = 1/2x'
