16. If y varies directly as x, and x = 9 when y = 15, find y when x = 33?​

Answer:

y=55 when x is 33

Step-by-step explanation:

Use the direct variation formula:

\frac{y}{x} =k  or \frac{y}{x} =\frac{y}{x}

Insert the given values:

\frac{15}{9}=\frac{y}{33}

To simplify the equation, cross multiply:

15(33)=9(y)\\\\495=9y

Isolate the variable. Divide both sides by 9:

\frac{495}{9} =\frac{9y}{9} \\\\55=y

Therefore, when x is 33, y is 55.

A home is to be built on a 56 foot 9 inch wide lot. The house is 5 feet 5 inches from the side of the lot and is 34 feet 10 inch
daser333 [38]
<span>Total lot - house -other side
=(56 ft 9 in) - (34 ft 10 in) - (5 ft 5 in)
=(55 ft 21 in) - (34 ft 10 in) - (5 ft 5 in)
=16 ft 6 in
Convert to inches: </span>16 ft x 12 in/ft)+ 6 in= Total in inches<span>192 in + 6 in= Total in inches
198 in= Total in inches 
Check: One side + house + other side = Lot width
(5 ft 5 in)+(34 ft 10 in)+(16 ft 6 in)=Lot width
56 ft 9 in=Lot width, which equals the given.</span>

Given the equation −4Square root of x minus 3 = 12, solve for x and identify if it is an extraneous solution.
Darina [25.2K]

Answer:

There is no solution for the given radical equation.

x = 225/16 is an extraneous solution.

Step-by-step explanation:

The given equation is  

Add 3 to both sides of the equation

Squaring both sides

Divide both sides by 16

Substituting back the value of x in original equation to check the extraneous solution.

 

Since -18≠ 12. Hence, the value of x does not satisfy the equation.

Therefore, x = 225/16 is an extraneous solution.
