Solve for x in the figure. 78° [(5x-210

Sergeeva-Olga [200]

Answer:

$78 = (5x - 2) \\ \\ 78 = 5x - 2 \\ \\ 78 + 2 = 5x \\ \\ 80 = 5x \\ \\ x = \frac{80}{5} \\ \\ x = 16$

it's was vertical angel they are equal ( = ) each other

F(x)=x-1/x^2-x-6 which is the graph of

hoa [83]

Answer:

The graph is attached below.

Step-by-step explanation:

As you have not added the graph, so I will be solving the function for a graph.

Given the function

$f\left(x\right)=x-\frac{1}{x^2}-x-6$

$x-\mathrm{axis\:interception\:points\:of\:}-\frac{1}{x^2}-6:$

$\mathrm{x-intercept\:is\:a\:point\:on\:the\:graph\:where\:}y=0$

$-\frac{1}{x^2}-6=0$

$-1-6x^2=0$

$\mathrm{No\:Solution\:for}\:x\in \mathbb{R}$

$\mathrm{No\:x-axis\:interception\:points}$

$y-\mathrm{axis\:interception\:point\:of\:}-\frac{1}{x^2}-6:$

$y\mathrm{-intercept\:is\:the\:point\:on\:the\:graph\:where\:}x=0$

As we know that the domain of a function is the set of input or argument values for which the function is real and defined.

$\mathrm{Domain\:of\:}\:-\frac{1}{x^2}-6\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x0\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:0\right)\cup \left(0,\:\infty \:\right)\end{bmatrix}$

$\mathrm{Since}\:x=0\:\mathrm{is\:not\:in\:domain}$

$\mathrm{No\:y-axis\:interception\:point}$

$\mathrm{Asymptotes\:of}\:-\frac{1}{x^2}-6:\quad \mathrm{Vertical}:\:x=0,\:\mathrm{Horizontal}:\:y=-6$

$\mathrm{Range\:of\:}-\frac{1}{x^2}-6:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)$

The graph is attached below.

How to solve this??? e^(2x) - e^x = 6

Ray Of Light [21]

$e^{2x}-e^x=6$
$(e^x)^2-e^x-6=0$
$(e^x-3)(e^x+2)=0$

$e^x=3$
$e^x=-2$

therefore $x=\ln3$ and $x=\ln-2$
because $\ln-2$ doesn't exist, the only solution to your equation is $x=\ln3$
