Y=-2/9x+2 turn this linear equation into standard form

1 answer:

3 0

Hi there!

Standard form is ax + by = c.

Now, we just need to simplify the equation enough so that we can get the answer:

y = -2/9x + 2
2/9x + y = 2

Since 2/9x + y = 2 is in standard form, it'd be the answer.

Hope this helps!

If u(x)=-2x^2+3 and v(x)=1/x what is the range of (u*v)(x) **the picture should help

nasty-shy [4]

We have that
$u(x)=-2 x^{2} +3 \\ \\ v(x)= \frac{1}{x}$
$u(v(x))=u( \frac{1}{x})=-2( \frac{1}{x} )^{2} +3 \\ u( \frac{1}{x})= \frac{(3 x^{2} -2)}{ x^{2} }$

using a graph tool
see the attached figure

The horizontal asymptote of this function is at y=3.
So,
the range of this function is from (−∞,3)
