The nature of a graph, which has an even degree and a positive leading coefficient will be<u> up left, up right</u> position

<h3 /><h3>What is the nature of the graph of a quadratic equation?</h3>

The nature of the graphical representation of a quadratic equation with an even degree and a positive leading coefficient will give a parabola curve.

Given that we have a function f(x) = an even degree and a positive leading coefficient. i.e.

y = f(x) = 2x²+ 4

The domain of this function varies from -∞ < x < ∞ and the parabolic curve will be positioned on the upward left and upward right x-axis.

write five pairs of integers (a,b) such that a divided / b is equal to 2 is is equal to -3 one such pair is is 6 and -2 because

nataly862011 [7]

Answer:

(10,5), (-12,-6), (-18, -9), (-8, -4), (20,10)

(-15, 5), (-18, 6), (-21,7), (33, -11), (24, -8)

Step-by-step explanation:

10/5=2, -12/-6=2, -18/-9=2, -8/-4=2, 20/10=2

-15/5= -3, -18/6= -3, -21/7= -3, 33/-11= -3, 24/-8= -3

ack has a collection of 10 pairs of gloves in his wardrobe. Before a business trip, he has to pack his luggage, and he selects 8

Leto [7]

Answer:

$\frac{{10 \choose 8}2^8}{{20 \choose 8}}\approx 0.091$

Step-by-step explanation:

We can think of the 10 pairs of gloves as simply being gloves of different colors. Picking no matching pair is the same as picking no 2 gloves of the same color. To compute the probability of doing so, we can compute the number of ways to select 8 gloves from different colors, and divide that by the total number of ways to select 8 random gloves out of the 20 gloves.

To compute the number of ways in which we can select 8 gloves from different colors, we can think of the choosing procedure as follows:

1st step- We choose from which 8 colors are we going to pick gloves from. So we have to pick 8 out of 10 colors. This can be done in ${10 \choose 8}$ ways.

2nd step - We now have to choose which glove are we going to pick from each of the chosen colors. Either the left one or the right one. For the first chosen color we have 2 choices, for the second chosen color we have 2 choices, for the third chosen color we have 2 choices, and so on. Therefore the number of ways in which we could choose gloves from the chosen colors is $2^8$

And so the total number of ways in which we could choose 8 gloves from different colors is

${10 \choose 8 }2^8$

Now, the total numer of ways in which we could choose 8 gloves out of the 20 gloves is simply ${20 \choose 8}$

So the probability of picking no mathing pair is

$\frac{{10 \choose 8}2^8}{{20 \choose 8}}\approx 0.091$

X over 2x+1. What is x?

tatiyna

Answer:

$x= - \frac{1}{2}$

Step-by-step explanation:

Given:

$\frac{2x+1}{x}$

Let us assume that this equation is equal to 0.

Hence $\frac{2x+1}{x}=0$

Now Solving the above equation we get,

$\frac{2x+1}{x}=0\\\\2x+1=0\\2x=-1\\x= - \frac{1}{2}$

Hence by solving the equation we get $x= - \frac{1}{2}$
