A=1 b=2
a = 1 \\ b = 2 \\ c =  - 35
\frac{ - b  \pm \sqrt{{b}^{2}  - 4ac} }{2a}
\frac{ - 2 \pm \sqrt{4 - 4(1)( - 35)} }{2}
\frac{ - 2 \pm \sqrt{144} }{2}  =  \frac{ - 2 \pm12}{2}  = 5 \: or \:  - 7

In a right triangle, Sin (30 + x) º = Cos (3x) º. What is the value of x?
pogonyaev

Answer:

x=15^\circ

Step-by-step explanation:

In a right triangle:

\sin \theta =cos(90^\circ-\theta) $ (Complementary angles)

Therefore, given:

Sin (30 + x) \º = Cos (3x) \º\\30+x+3x=90^\circ\\30+4x=90^\circ\\4x=90^\circ-30^\circ\\4x=60^\circ\\$Divide both sides by 4\\x=15^\circ

What is the inverse of the function f(x) = 2x + 1?
timama [110]

Answer:

  (a)  h(x) = 1/2x -1/2

Step-by-step explanation:

The inverse of the function y = f(x) is found by solving x = f(y).

__

<h3>setup</h3>

  x = f(y)

  x = 2y +1 . . . . . . use the definition of f(x)

<h3>solution</h3>

  x -1 = 2y . . . . . subtract 1

  (x -1)/2 = y . . . . divide by 2

  y = 1/2x -1/2 . . . . eliminate parentheses

  h(x) = 1/2x -1/2 . . . write in functional form

The inverse of f(x) = 2x+1 is ...

  h(x) = 1/2x -1/2

Which two numbers add up to 3 and are multiplied to 4
DedPeter [7]
There are no two numbers that will add up to 3 and when multiplied become 4.

However there are 2 numbers if you multiply them it is -4. And when you add them it is 3. Those two numbers would be 1 and -4
