(x+5,y-6) is the coordinate notation.
Answer:
.12
Step-by-step explanation:
18=3(x-1)
18=3x-3
18-3=3x
15=3x
15/3=x
x=5
(6n^2-4)+(-2n^2+9)
6n^2-4-2n^2+9
4n^2+5
Hope this helps!
Answer:
See below
Step-by-step explanation:
y = -6x^2 + 24x-100
solve for 'x'
y + 100 = -6x^2 + 24x = -6(x^2-4x) complete the square for x
(y+100) /(-6 ) = (x-2)^2 -4 add 4 to both sides
(y+100)/(-6) +4 = (x-2)^2 sqrt both sides
sqrt [ ( y+100)/(-6) + 4 ] + 2 = x change x and y
y = ± sqrt [ (x+100)/(-6) + 4 ] + 2 simplify (if needed)
<u>y = ± sqrt( -x/6 -12.666) + 2 </u>
