Determine whether the relation is a function.<br><br> (4,0), (4,1), (5,2), (6,3), (6,4)
Alexxandr [17]

Answer:

The relation is not a function.

Step-by-step explanation:

In order for a relation to be a function, there can only be one output for every x value. If you were to graph this equation, it would not pass the vertical line test, as 4 has two outputs (0 and 1) and 6 has two outputs (6 and 4).

What are the roots of the function y = 4x2 + 2x - 30?
a_sh-v [17]

Answer:

-3, 5/2

Step-by-step explanation:

What are the roots of the function y = 4x2 + 2x – 30?

To find the roots of the function, set y = 0. The equation is 0 = 4x2 + 2x – 30.

Factor out the GCF of : 2, so the equation becomes 0 = 2(2x2+x-15)

Next, factor the trinomial completely. The equation becomes: 0=2(x+3)(2x-5)

Use the zero product property and set each factor equal to zero and solve.

x+3=0      2x-5 = 0

x = -3, 5/2

The roots of the function are -3, 5/2.

Hope this helped!

Luis hizo un viaje en el coche en el cual consumio 20 l de gasolina. el trayecto lo hizo en dos etapas en la primera consumio 2/
algol13

Answer: 24\ liters

Step-by-step explanation:

Let be "x" the amount of gasoline in liters that the car's tank had at the beginning of the trip.

 1. In the first part of the trip the amount of gasoline the car used can be expressed as:

 \frac{2}{3}x

2. After the first part of the trip, the remaining was:

x-\frac{2}{3}x=\frac{1}{3}x  

3. In the second part of the trip the car used \frac{1}{2} of the remaining. This is:

(\frac{1}{3}x)(\frac{1}{2})=\frac{1}{6}x

4. The total amount ot gasoline used in this trip was 20 liters.

5. Then, with this information, you can write the following equation:

\frac{2}{3}x+\frac{1}{6}x=20

6. Finally, you must solve for "x" in order to find its value. This is:

\frac{2}{3}x+\frac{1}{6}x=20\\\\\frac{5}{6}x=20\\\\5x=120\\\\x=24
