Which function has the same graph as x + y= 11?

leonid [27]

Answer:

f(x) = 11 - x

Step-by-step explanation:

We have to find a function that has a graph as x + y = 11.

Now, the equation given is

x + y = 11

⇒ y = 11 - x

So, if we consider x as an independent variable and y as a dependent variable whose values are dependent on the values of x, then er can write y = f(x) = 11 - x

So, the function f(x) = 11 - x has the same graph as x + y = 11. (Answer)

galben [10]

Answer:

$2.3\times 10^{-2}$

Step-by-step explanation:

Given equation,

$2.9\times 10^{-7}=\frac{(x)(x)^2(4.6)}{(4.6)^2(3)^2}$

$2.9\times 10^{-7}=\frac{x^3}{9\times 4.6}$

$(\because a^m = \frac{1}{a^{-m}})$

By cross multiplication,

$2.9\times 9\times 4.6\times 10^{-7}=x^3$

$120.06\times 10^{-7}=x^3$

$\implies x = (120.06\times 10^{-7})^\frac{1}{3}$

$=0.0228980999294$

$\approx 0.023$

$=2.3\times 10^{-2}$
