3 0

Answer:

  a proportional relationship exists if the ratio of values is a constant

Step-by-step explanation:

The equation describing a proportional relationship is ...

   y = kx

If you are given a table of values of x and y, they will be proportional if ...

  y/x = k

for all (x, y) pairs.

Find the area of the region bounded by the y-axis, the line y=6, and the line y = 1/2.
Ghella [55]

Solution:

As region bounded by y-axis, the line y=6, and the line y=1/2 is a line segment of definite length on y-axis.

We consider a line , one dimensional  if it's thickness is negligible.

So, Line is  two dimensional if it's thickness is not negligible becomes a quadrilateral.

So, Area (region bounded by y-axis, the line y=6, and the line y=1/2 is a line segment of definite length on y-axis)= Area of line segment between [,y=6 and  y=1/2.]= 6-1/2=11/2 units if we consider thickness of line as negligible.

COMBINATION/PERMUTATION MATH HELP???
Artyom0805 [142]
This type of combination problem involves combined probability, or the chance that a specific set could be chosen based on the probability of multiple variables.

The number that could be generated follows the example:

XXYZZZZ

where X describes a letter, and Y describes a number that isn’t zero, and Z describes any number.

Two probabilities exist in this situation, depending on the circumstances of the question. By pressing any number once, only 8 letters can be used (ten digits, minus the one and two keys, since they don’t have letters). This means that the probability of this event is:

8 x 8 x 9 x 10 x 10 x 10 x 10

where the two eights are for the letters, the nine is for the digit that isn’t zero, and the tens are for any numbers from the keypad. This permutation yields 5,760,000 choices.

If you are allowed to press the numbers more than once to generate a letter, then the probability changes to account for the entire alphabet. The new probability of this event is :

26 x 26 x 9 x 10 x 10 x 10 x 10

where this permutation yields 60,840,000 choices.

Hope this helps!

maw [93]

Answer:

x=-6

Step-by-step explanation:

The axis of symmetry is the lowest (or highest) point.  It is the line where it becomes the mirror image.

Looking at the graph, this is the line x=-6

x = -6
