Answer:

Hello! I am also having trouble in algebra! From what I can see so far this is what the problem should look like...

Step-by-step explanation:

A. Yes, it s a linear function because it matches the equation y=mx+b

B. The domain is 1, 2, 3 , 4, and 5. This is because there are 5 services you can choose from. The domain is discrete because you can't have half a service.

C. Because I'm also doing this book (I'm in Algebra 1 in 8th grade), I'm also just learning this! So sorry, but I don't know how to solve this one either... can someone please help?

Thanks! Also, just a tip, if you're having trouble ever again go to slader.com where they have all the answers to any textbook. They also have really good explanations! However, for this one, I didn't understand it on slader so I came on here! Good luck and if anyone can help with C that would be much appreciated.

Option A:

The simplest radical form of x is 3\sqrt{15}.

Solution:

Hypotenuse = 16 in

Two sides are 11 in and x.

To find the value of x:

Pythagoras theorem:

In a right angle triangle, the hypotenuse is equal to the sum of the other two sides.

11^2+x^2=16^2

121+x^2=256

Subtract 121 from both sides of the equation.

121+x^2-121=256-121

x^2=135

Taking square root on both sides of the equation.

\sqrt {x^2}=\sqrt {135}

x=3\sqrt {15}

Hence option A is the correct answer.

Hence the simplest radical form of x is 3\sqrt{15}.

Given that 3(x-c)=2x+5 where c is an integer, shoe that x cannot be a multiple of 6
olga nikolaevna [1]

Answer:

The explanation in the procedure

Step-by-step explanation:

we have

3(x-c)=2x+5

solve for c

3x-3c=2x+5

3c=3x-2x-5

3c=x-5

c=(x-5)/3

For x=6 -----> Find the value of c

c=(6-5)/3=1/3 ------> is not an integer

therefore

x cannot be a multiple of 6

maw [93]

Answer:

  m∠2 = 16° or 25°

Step-by-step explanation:

The sum of angles 1 and 2 is congruent to angle CED.

  20° +(x^2)° = (9x)°

  x^2 -9x +20 = 0 . . . . . divide by °, put in standard form

  (x -5)(x -4) = 0 . . . . . . . factor

  x = 5 or 4

  m∠2 = (x^2)° = (5^2)° or (4^2)°

  m∠2 = 16° or 25°
