Step-by-step explanation:
Just divide it using a calculator, although I don't know how to convert it into a fraction. Sorry!
Solution for 1/3*-1/9y=3 equation:
<span>y in (-oo:+oo)
((-1*(1/3))/9)*y = 3 // - 3
((-1*(1/3))/9)*y-3 = 0
((-1/3)/9)*y-3 = 0
-1/27*y-3 = 0 // + 3
-1/27*y = 3 // : -1/27
y = 3/(-1/27)
y = -81
</span><span>y = -81</span>Solution for 2/3*1/5y=9 equation:
<span>y in (-oo:+oo)
((1*(2/3))/5)*y = 9 // - 9
((1*(2/3))/5)*y-9 = 0
((2/3)/5)*y-9 = 0
2/15*y-9 = 0 // + 9
2/15*y = 9 // : 2/15
y = 9/2/15
y = 135/2
y = 135/2

Y= x²- 6x +7
Vertex form is y= a(x-h)² +k
The vertex form of this equation would be y= (x-3)²- 2 because if we transform to the standard form it would be equal to y= x²-6x+7 so we just have to complete the perfect square (which means to complete, following the rules, with the numbers that will make this equation right in the standard form).
How our x² is equal to 1 on our standard form (like it is not 2x², it is just x²), our ''a'' on the vertex form is 1 so we simply don't have to write the 1 in front of it so it stays y= 1(x-3)² -2 or y=(x-3)²-2. Look how it works: (x-3)² we use the rule of a²+2ab+c² which is the square of the first x² plus two times the first term times the second -6x plus the square of the last term (-3)² = 9 so we have x²-6x+9 - 2 that gives us the standard form x²-6x+7. So, that's true that the vertex form is y=(x-3)²-2
