Solve the equation Square root of x minus 5+ 7 = 11 for the variable. Show each step of your solution process. (10 points)
Murrr4er [49]

\sqrt{x - 5} + 7 = 11

(\sqrt{x-5}) ^{2} = (4)^{2}

|x - 5| = 16

x - 5 = +/- 16

x - 5 = 16     or     x - 5 = -16

<u>   +5</u>   <u>+5   </u>           <u>   +5 </u>    <u>+5  </u>

    x = 21       or        x = -11

Answer: x = {21, -11}

which table represents viable solutions for y=5x, where x is the number of tickets sold for the school play a y is the amount of
STALIN [3.7K]

Given:

The given equation is:

y=5x

Where x is the number of tickets sold for the school play a y is the amount of money collected for the tickets.

To find:

The correct table of values from the given options.

Solution:

We know that the number of tickets and amount of money collected for the tickets cannot be negative. So, options A and B are incorrect.

We have,

y=5x

For x=0,

y=5(0)

y=0

For x=10,

y=5(10)

y=50

For x=51,

y=5(51)

y=255

For x=400,

y=5(400)

y=2000

In option C, all the ordered pairs (0,0), (10,50), (51,255), (400,2000) are in the table. So, option C is correct.

For x=65

y=5(65)

y=325

Since the ordered pair (65,350) does not satisfy the given equation, therefore the option D is incorrect.

Hence, the correct option is C.
