Given f (x) = -12x + 72, find x when f(x) = 24.

Neko [114]

Answer:

x = 4

Given:

f(x) = -12x + 72

f(x) = 24

Step-by-step explanation:

$= > - 12x + 72 = 24 \\ \\ = > - 12x = 24 - 72 \\ \\ = > \cancel{- }12x = \cancel{-} 48 \\ \\ = > 12x = 48 \\ \\ = > x = \frac{48}{12} \\ \\ = > x = 4$

Can someone help me please? I don't nderstand this

musickatia [10]

Answer:

perpendicular(p)=5

base(b)=12

hypotenuese(h)=?

using pytha goras theorem,

h^2=P^2+b^2

h^2=(5)^2+(12)^2

h^2=25+144

h^2=169

h^2=13^2

I don’t understand how to do this

schepotkina [342]

Answer:

The solution is $x =0.$

Step-by-step explanation:

The equation

$\bold{(1).}\: sin(\dfrac{3\pi }{2} +x)+sin(\dfrac{3\pi }{2} +x) =-2$

can be rewritten as

$2* sin(\dfrac{3\pi }{2} +2) =-2$

and can be further simplified to

$sin(\dfrac{3\pi }{2}+x ) =-1$ .

Now, taking the inverse sine of both sides we get:

$sin^{-1}(sin(\dfrac{3\pi }{2} +x) =sin^{-1}(-1)$

$\bold{(2).}\: \dfrac{3\pi }{2} +2 =sin^{-1}(-1)$

The value of the right side on the interval $[0,2\pi)$ is

$sin^{-1}(-1) = \dfrac{3\pi}{2} \: \:( \text{or }270^o)$ ,

which makes the equation (2)

$\dfrac{3\pi }{2}+x =\dfrac{3\pi}{2}$

solving for $x$ gives

$\boxed{x = 0}$

which is our solution.
