Answer:

  6

Step-by-step explanation:

If we place no restrictions on the values of the variables, there are an infinite number of possible solutions.

In this scenario, it is reasonable to require all variables have non-negative integer values. That restricts the solutions to ...

  (x, y, z) ∈ {(15, 20, 0), (12, 22, 1), (9, 24, 2), (6, 26, 3), (3, 28, 4), (0, 30, 5)}

There are 6 solutions to her problem.

noname [10]

Simetría Traslacional

En este caso la imagen no se refleja, ni gira alrededor de una eje, sino que más bien es como si se multiplicara el objeto que aparece en ella, como ocurre por ejemplo con la siguiente fotografía.

si calculamos y planteamos todo lo dicho tendremos que:

AR=360/3=120

ojo:tambien se puede venir los calculos del cuadro de simetria y solo cuando se te presenta una sametrica indiguididuil bueno asi yo lo llamo espero te halla servido

If we change the equation for the quadratic function form y=2x^2+3x-5 to y= -2x^2+3x-5 describe what changes in the graph.
r-ruslan [8.4K]
First convert them to vertex form

first one is y = 2(x + 0.75)^2 - 6.125

2nd is   y = -2(x - 0.75)^2 - 3.875

the -2  will cause  a reflection of the first equation in the x axis . then a translation  down  of 6.125 + 3.875 = 10 units , followed by
  a translation of  -0.75-0.75 = -1.5 units to the right = 1.5

At how many points does the graph of the function below intersect the x-axis?
kotegsom [21]

A. 2 is the right answer

Step-by-step explanation:

Given function is:

y=3x^2-5x+1

The graph of any function is made by plugging in the inputs and finding the respective outputs hence creating points on graph.

The graph of function can be created using online graphing tools.

We have used the online graphing calculator "Desmos" to draw the graph of the given function (Picture Attached)

In the picture we can see that the line of graph intersects the x-axis on two points only.

Hence,

A. 2 is the right answer

kenny6666 [7]

Answer:

Bb or BB = 75%

Explanation:

In order to solve this question we have to use the Punnett square.

The Punnett square demonstrate the genetic results when two individuals cross. In order to make the square, we have to draw a big square with small squares inside, each representing all possible combinations of alleles. Since we have 2 alleles we have 4 possible combinations, that means 4 small squares.

In the up part of the square we introduce the alleles of the parent 1 and in the left part the alleles of parent 2. The results will be written in the small squares.

The attached image represents the crossing of two heterozygotes Bb x Bb

Represented by red there's 25% of probability of the puppy be homozigot BB, that means he will be black.

Represented by green there's 50% of probability of the puppy be heterozigot Bb, that means he also will be black, since B is dominant.

Represented by blue there's 25% of probability of the puppy be homozigot bb. That means he will be brown, since there's no dominant B there.

Total: 25% (BB) + 50%(Bb) = 75% of being black
