Horizontal Shrink: y = cos 2x or if the coefficient of x is greater than 1
Vertical Stretch: y = 2 cos x or if the coefficient if cos x is greater than 1
Horizontal Stretch: y = cos (1/2) x or if the coefficient of x is less than 1
Vertical Shrink: y = (1/2) cos x or the coefficient of cos x is less than 1

The base value is 1 since it is the original coefficient of x and cos x. The values would adjust depending on the original coefficients.

Step-by-step explanation:

\frac{x - 9}{15}  =  \frac{2x - 9}{10}  \\

\frac{x - 9}{3}  =  \frac{2x - 9}{2}  \\

2( x - 9) = 3(2x - 9) \\

2x - 18 = 6x - 27

27 - 18 = 6x - 2x

9 = 4x

x =  \frac{9}{4} \\

Please help solve equation
gregori [183]
<h2><u>Solution</u> :-</h2>

Height of Eric = 6 + 1/6 feet

= 37/6 feet

Height of his brother = 5 + 3/4 feet

= 23/4 feet

Difference between their height :

= 37/6 - 23/4

= (74 - 69)/12

= 5/12

<u>Hence</u>,

Eric is 5/12 feet taller than his brother.
