Answer:

-1/9, 1/9

Step-by-step explanation:

If we represent this with an equation, we get 3 + |-9x| = 4. Subtract 3 from both sides and we get |-9x| = 1. There are two solutions to this, 1/9 and -1/9, since they both multiply to a number whose absolute value is 1. (-9 * 1/9 = -1, 9 * 1/9 = 1. -1 has an absolute value of 1.)

Answer:

The sin of 20 degrees is 0.34202, the same as sin of 20 degrees in radians. To obtain 20 degrees in radian multiply 20° by / 180° = 1/9 . Sin 20degrees = sin (1/9 × .

What is the inverse function of F(x) = -3/2x - 8

GrogVix [38]

Answer:

f-1(x)=- $\frac{2}{3}$ x- $\frac{16}{3}$

Step-by-step explanation:

First, switch f(x) to the variable "y".

y=- $\frac{3}{2}$ x-8

Next, swap "x" and "y" with each other.

x=- $\frac{3}{2}$ y-8

Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...

2x=-3y-16

Now move -16 to the left side.

16+2x=-3y

To get "y" by itself, lets divide each side by -3. Our result is...

y=- $\frac{2}{3}$ x- $\frac{16}{3}$

To finish the problem off, replace y with f-1(x) and your complete answer will be...

f-1(x)=- $\frac{2}{3}$ x- $\frac{16}{3}$

Evaluate the expression for the given value of the variables.

zzz [600]

For every c substitute 4 and for every d substitute -2

c=4
d=-2

6c + 5d - 4c - 3d + 3c - 6d

= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)

=24+(-10)-16-(-6)+12-(-12)

=24-10-16+6+12+12

=28
