Answer:

x , reciprocal= 1/x

x+2(1/x)=27/5

x+2/x=27/5

x^2+2=27/5*x

x^2-27/5*x+2=0

(x-5)(x-2/5)=0

x=5, 2/5

Hello,

$m(x) = 5x + 4\\n(x) = 6 x-9\\Part\ A:\\(m + n)(x)=m(x)+n(x)=5x+4+6x-9=11x-5\\Part\ B:\\ (m-n)(x)=m(x)-n(x)=5x+4-(6x-9)=5x-6x+4+9=-x+13\\Part\ C: \\(m\ o\ n)(x)=m[n(x)]=m(6x-9)=5*(6x-9)+4=30x-45\\$

A ball is thrown at a 30 degree angle above the horizontal with a speed of 10 ft/s. After 0.50s the horizontal component of it's velocity will be the same. In a projectile motion the horizontal component of the velocity is said to be constant. Therefore, it will be equal to the initial velocity.

What is the line of symmetry of the parabola y=x2+6x-9?

Rzqust [24]

First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry

1st: group the number
(X2+6x)-9

2nd: use b/2

6/2 = 3 , 3^2= 9

(X2+6x+9)-9-9

(X2 + 3)-18

Vertex is 3,-18 so the symmetry is 3
