Answer:

Step-by-step explanation:

20 = 8x + 4r can be rewritten in multiple ways.

1.  Reduce the coefficients:  5 = 2x + r

or

2.  Solve for r:  r = 5 - 2x

or

                                 5 - r

3.  Solve for x:  x = -----------

What is 8.545 kilograms rounded to the nearest hundredth?
ohaa [14]
8.545 rounded to the nearest hundredth is 8.55. I think so because the number in the hundredth place is 4, the number on the right of it is 5. 5 is equal to 5 so the 4 turns into 5

Can you solve this for me
guajiro [1.7K]
g(h(x))=g(\sqrt{x+7})=\dfrac{2}{\sqrt{x+7}+9}\\\\f(g(h(x)))=f\left(\dfrac{2}{\sqrt{x+7}+9}\right)=7\cdot\left(\dfrac{2}{\sqrt{x+7}+9}\right)+9\\\\f(g(h(x)))=\dfrac{14+9\sqrt{x+7}+81}{\sqrt{x+7}+9}\\\\(f\circ g\circ h)(x)=\dfrac{95+9\sqrt{x+7}}{9+\sqrt{x+7}}

With some extra effort, the radical can be removed from the denominator. That result is

(f\circ g\circ h)(x)=\dfrac{9x+14\sqrt{x+7}-792}{x-74}

The preferred form would be the one with the radical in the denominator, as it correctly shows the domain of the function to be x ≥ -7. The function actually is defined at x=74, which the "rationalized" form does not show.
