Find the standard equation of a parabola with a vertex of (-3,1)

kkurt [141]

1. Parabola's equation is y = a(x + b)^2 + c, where (b, c) is the vertex.
2. We have y = a(x - 3)^2 + 1
3. Take everything to the left side:
-a(x - 3)^2 + y - 1 = 0
That's the standard equation. Hope this helps! :)

5r^2-13r-6=0 How do I solve this

frosja888 [35]

$5 {r}^{2} - 13r - 6 = 0 \\ a = 5 \\ b = - 13 \\ c = - 16 \\$

r= -(-13)±>

$\sqrt{( - 13) {}^{2} } - 4.5( - 6)$

2.5

r= 13±17

10

r=13+17

10

r=13-17

10

$r = 2 \\ r = \frac{ - 2}{5}$

Simplify: 3m/m-6*5m^3-30m^2/5m^2 A.7 B.m+7 C.m+8 D.3m

VLD [36.1K]

I think you meant this: (3m/m-6)*(5m^3-30m^2/5m^2)
If that's the case, the simplified form:
=3m
