Answer:

x = 36

Step-by-step explanation:

y = \frac{x}{4} - 7

and y = 2 so...

2 = \frac{x}{4} - 7

Bring -7 to the other side to get +7

2 + 7 = \frac{x}{4}

9 = \frac{x}{4}

Bring the 4 in \frac{x}{4}  to the other side to get x4

9 x 4 = x

∴ x = <u>36</u>

What are the zeros of the polynomial function? <br><br> F(x)= x^2 +12x
Pavel [41]

Answer:

x = 0 and x = -12 are the two zeroes

Step-by-step explanation:

"Zeroes" of a function are also called the solutions, roots or x intercepts.

The zeroes are the numbers that give the function a values of 0, so find what value for 'x' yields F(x) = 0 as a result.

With quadratic equations (equations with x² as the largest exponent), you factor the equation.  

Step 1: Set the equation equal to zero

  x² + 12x = 0

 Depending on the equation, there are several methods you can use to factor, for this one we can factor out an 'x' since both terms have an 'x' in them.  We get...

  x(x + 12) = 0      

So now, using the "zero product property" which means that if two things are multiplied together, and the result is zero, then either the first term is zero, the second term is zero, or they are both zero.  So we set each term equal to zero and solve.

So

either    x = 0     or        x + 12 = 0

Solve each for x to get your two anwers.

x= 0 is already solved, so 0 is our first zero

Now solve

x + 12 = 0  

  x = -12             (subtract 12 from both sides to isolate x)

sashaice [31]

Answer:

616/2500

Step-by-step explanation: You first have to find the number of times a Blue marbles was chosen: 22

Then find the total number of marbles that were chosen. Make a fraction out of it: 22/50

You then see how many times tails was flipped: 28

Do the same thing again: 28/50

Then multiply the two fractions together:

22/50 * 28/50 = 616/2500
