$\bf \begin{cases} f(x) = x\\ g(x) = 2x+7 \end{cases}~\hspace{7em}g(x)=11\implies \stackrel{g(x)}{11}=2x+7 \\\\\\ 4=2x\implies \cfrac{4}{2}=x\implies \implies \boxed{2=x} \\\\[-0.35em] ~\dotfill\\\\ f[90x]\implies f\left[90\left( \boxed{2} \right)\right]\implies f(180)=\stackrel{x}{180}$

What can you tell about a triangle when vibe three side lengths

ale4655 [162]

Answer:All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.

Hope it helps...

Describe using words in a sentence the transformations that must be applied to the graph of f to obtain thegraph of g(x) = -2 f(

grin007 [14]

we have

f(x)

and

g(x)=-2f(x)+5

step 1

First transformation

Reflection about the x-axis

f(x) -----> -f(x)

step 2

Second transformation

A vertical dilation with a scale factor of 2

-f(x) ------> -2f(x)

step 3

Third transformation

A translation of 5 units up

-2f(x) -------> -2f(x)+5
