Answer:

x          y

-10      -1

0         4

4          6

6          8

Step-by-step explanation:

an output is 4 more than half its input.

Input of a function is x and the output of a function is y

output y is 4 + half of input x

y= \frac{1}{2} x + 4

Now we complete the below table, plug in the value of x  and find out y

x = -10 , y= \frac{1}{2}(-10) + 4=-5+4 = -1

x = 0 , y= \frac{1}{2}(0) + 4=0+4 = 4

x = 4 , y= \frac{1}{2}(4) + 4=2+4 = 6

x = 8, y= \frac{1}{2}(8) + 4=4+4 = 8

Explain how the energy of a toy car is transformed as it slides down a ramp. Give evidence that the energy of the car remains th
yaroslaw [1]
<span>At the top of a ramp, all of the energy of the car is potential: that is, it has yet to be moved but has the ability to move. As the car is sliding down the ramp, the potential energy is being transformed into kinetic energy, which reaches a maximum at halfway down the ramp. After this point, the kinetic energy begins to lessen and the potential energy begins to increase, until the car comes to a full stop, at which point kinetic energy is at zero and the potential energy is again at a maximum.</span>

Solve for the variable: 12 = 5x = 7
IrinaVladis [17]

Hello from MrBillDoesMath!

Answer:  x = 1

Discussion :

Per the author, the equation to solve is  12 = 5x + 7

Isolate the "x" variable by subtracting 7 from both sides of the equation:

12 = 5x + 7

-7 =        -7

---------------------

12-7 = 5x + 0


or


5 = 5x

Dividing both sides by 5 gives x - 1

What are the possible rational zeros for f(x)=3x^4+x^3-13x^2-2x+9?
zaharov [31]

Answer:

Option 4 (±1, ±1/3, ±3, ±9) is the correct option.

Step-by-step explanation:

The given expression is f(x)=3x^{4}+x^{3}-13x^{2}-2x+9

We have to find the possible rational zeros for the function.

So by the rational zero theorem factors will be

=±(Factors of constant term 9)/±factors of coefficient of x^{4}

=±(Factors of 9)/±(Factors of 3)

=±(1, 3, 9)/±(1, 3)

=±(1, 3, 9, 1/3)

So option 4 is the correct answer.
