If one number is five more than another number, and the smaller number is half of the larger number, what are the two numbers?
Ymorist [56]

Answer:

<h2>Larger number = 10</h2><h2>Smaller number = 5</h2>

Step-by-step explanation:

Let larger number be x

Let smaller number be y

x = 5 + y---> equation (i)

y =  \frac{1}{2} x

x = 2y-----> equation (ii)

Equate equation (i) and (ii),

5 + y = 2y

Move variable to L.H.S and change its sign:

Similarly, Move constant to R.H.S and change its sign

y - 2y =  - 5

- y =  - 5

The difference sign (-) will be cancelled on both sides

y = 5

Putting the value of y in equation (ii) in order to find the value of X ( larger number)

x = 2y

Plug the value of y

= 2 \times 5

Calculate the product

= 10

Hence,

Smaller number = 5

Larger number = 10

Hope this helps..

Best regards!!

If (x)=<br> X-2<br> and d(x) = x + 3, what is the domain of (cd)(x)?
Nata [24]

Answer:

Option (2)

Step-by-step explanation:

Given functions are,

c(x) = \frac{5}{x-2}

d(x) = x + 3

Equation of the composite function will be,

(cd)(x) = c(x) × d(x)

          = \frac{5}{(x-2)}\times (x+3)

          = \frac{5(x+3)}{(x-2)}

This function is defined only when denominator is not equal to zero.

(x - 2) ≠ 2

Therefore, for real numbers except x = 2 will be the domain of the composite function.

Option (2) will be the answer.
