Y should also be halved.

For example, if x=4 and y=2, x=2y.
If x is halved for x=2, you get 2=2y, or y=1, which is still one half of x, so the proportion remains the same.

You have two exponential functions. One function has the formula g(x) = 5 x . The other function has the formula h(x) = 5-x . Wh

AVprozaik [17]

Given the exponential functions $g(x)= 5^{x}$ and $h(x)= 5^{-x}$

$k(x)=(g-h)(x)$
$k(x)=g(x)-h(x)
$
$k(x)= 5^{x} - 5^{-x}$
$k(x)= 5^{x} - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{x} 5^{x} }{ 5^{x} } - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{2x} }{ 5^{x} } - \frac{1}{ 5^{x} }$
$k(x)= \frac{ 5^{2x}-1 }{ 5^{x} }$

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

1/4 of the 300 skiers are beginners......1/4 of the 260 snowboarders are beginners..

so we want the total number of beginners..

the distributive property in this situation would be :

1/4(300 + 260) .......to solve this, u first have to get rid of the parenthesis. To do this, u multiple the number directly to the left of the parenthesis, by everything in the parenthesis.....u distribute it.

1/4(560).....now we multiply

560/4 = 140

this way

1/4( 300 + 260) = 1/4(300) + 1/4(260) = 300/4 + 260/4 = 75 + 65 = 140
