Step 1: Substitute -2 in for x in the equation.
** Remember the f(x) is y, not x

f(x) = -2 - 7

Step 2: Solve the math problem that you are left with.
f(x) = -9
__________________________________________________________

f(x) = -9 is your final.

F(x) = x - 7
x = -2

f(-2) = -2 - 7
f(-2) = -9

Step-by-step explanation:

charging the phone for 1 minute ,it has 2%

i.e,1----->2

After 2 minutes from that time ,i.e total 3 minutes

it has 6% charge

i.e,3--------->6

from the both the above cases ,1 minute provide 2%=6/3

=2

Hence,

for getting 50%charge=50/2

=25 min

and,for 90 %charge=90\2

=45 min

Please please please please help i need to pass please
labwork [276]

Answer:

D

Step-by-step explanation:

Solution:-

The standard sinusoidal waveform defined over the domain [ 0 , 2π ] is given as:

                                   f ( x ) = sin ( w*x ± k ) ± b

Where,

                 w: The frequency of the cycle

                 k: The phase difference

                 b: The vertical shift of center line from origin

We are given that the function completes 2 cycles over the domain of [ 0 , 2π ]. The number of cycles of a sinusoidal wave is given by the frequency parameter ( w ).

We will plug in w = 2. No information is given regarding the phase difference ( k ) and the position of waveform from the origin. So we can set these parameters to zero. k = b = 0.

The resulting sinusoidal waveform can be expressed as:

                           f ( x ) = sin ( 2x )  ... Answer

Solve for y. 3y – 12 = –6                                           A. –54          B. 2          C. 18          D. –6
erastova [34]
3y - 12 = -6
3y = 6                 | Add 12 to both sides
 y = 2                  | Divide by 3 on both sides
