When using distributive properties yes.

Yes, this is true. When using the distributive property, you do the number times the letters/numbers inside and do the operation that was inside the parenthesis. So, you do 5 times p and 5 times c. The operation inside the parenthesis what addition, so you add the two products. The new equation would be 5p+5c. So, as an inequality, 5p+5c=5(p+c).

3x - 3y = -12      ------------- (1)
7x + 2y = -19     --------------(2)

(1) x 2 : 6x - 6y = - 24       ----------- (1a)
(2) x 3 : 21x + 6y = -57     ----------- (2a)

(1a) + (2a) : 27x =  - 81
                        x = - 3

Sub x = -3 into (1) :  3(-3) - 3y = - 12 
                                               y = - 12  + 9
                                               y = - 3

Use f(x) = 1)2 and f^-1(x) = 2x to solve the problems. a) f(2) b)f^-1(1) c)f^-1(f(2))​
Luden [163]

a) f (2)  = 1

b) f^{-1}(1)=2

c) f^{-1}(f(2))=2

<u>Step-by-step explanation:</u>

f^{-1} - Indicates that we have to find the inverse of the function

Given data:

f(x)=\left(\frac{1}{2}\right) x --------> eq.1

f^{-1}(x)=2 x ---------> eq.2

To find f(2), f^{-1}(1), f^{-1}(f(2))

Case a)

Now, substitute x = 2 in the equation 1 to find f (2)

 f(2)=\left(\frac{1}{2}\right) \times 2=1

Case b)

Now, substitute x = 1 in the equation 2 to find  f^{-1}(1)

  f^{-1}(1)=2(1)=2

Case c)

In general,

    f^{-1}(f(x))=f\left(f^{-1}(x)\right)=x

Thereby,

   f^{-1}(f(2))=2 \text { where } x=2
