What does x equal in 7+2/5x=-5
Anna007 [38]

Answer:

x = -30

Step-by-step explanation:

subtract 7 from both sides ( 7+2/5x -7, -5-7 )

simplify ( 2/5x = 12 )

multiply both sides by 5 ( 2/5x times 5 = 5 (-12) )

simplify ( 2x = -60 )

divide both sides by 2 ( 2x / 2, -60 / 2 )

x = -30

Write the equations in graphing form, then state the vertex of the parabola or the center and radius of the circle.
Sati [7]
All we need is to put this form in the vertex form f(x) = (ax+b)^2 + c

So we have <span>f (x)= 3x^2+12x+11 ....

Let's complete the square (if you aware of it)
</span><span>
f(x)= 3x^2+12x+11 = 3(x^2+4x)+11 = 3(x^2+4x+4-4)+11
=</span><span> 3([x^2+4x+4]-4)+11 = 3[(x+2)^2-4]+11 =3</span><span>(x+2)^2 - 12 +11 = 3</span><span><span>(x+2)^2 -1

so our form would be:

f(x)=3(x+2)^2-1


Here is a parabola with vertex of (-2,-1) and with positive </span> slope (concave up)





</span>

I hope that helps!
