The correct answer is: slope-intercept form

Step-by-step explanation:

Step 1

Recall that the first step in solving a system of linear equations using the substitution method is to solve one of the equations for one of its variables.

Of all the forms listed, only the slope-intercept form of an equation automatically has one of its variables solved-for (point-intercept form is not a real form). This means that if one of the equations in a system is already in slope-intercept form, then the first step can be skipped in using the substitution method.

Step 2

Match your solution to the correct answer choice.

Answer choice C is the only answer choice that identifies the form of linear equation that is the simplest to start when using the substitution method. Select answer choice C and move on to the next question.

Answer:

  A. point-slope form

Step-by-step explanation:

In general, the equation in point-slope form will give an expression that can substitute for "y", as that form is ...

  y = [something]

_____

In specific instances, the other forms of the linear equations may work, but that is not guaranteed.

If the Math Olympiad Club consists of 11 students, how many different teams of 3 students can be formed for competitions?
vivado [14]

Answer:

165 different teams of 3 students can be formed for competitions

Step-by-step explanation:

Combinations of m elements taken from n in n (m≥n) are called all possible groupings that can be made with the m elements so that:

  • Not all items fit
  • No matter the order
  • Elements are not repeated

That is, a combination is an arrangement of elements where the place or position they occupy within the arrangement does not matter. In a combination it is interesting to form groups and their content.

To calculate the number of combinations, the following expression is applied:

C=\frac{m!}{n!*(m-n)!}

It indicates the combinations of m objects taken from among n objects, where the term "n!" is called "factorial of n" and is the multiplication of all the numbers that go from "n" to 1.

In this case:

  • n: 3
  • m: 11

Replacing:

C=\frac{11!}{3!*(11-3)!}

Solving:

C=\frac{11!}{3!*8!}

being:

  • 3!=3*2*1=6
  • 8!=8*7*6*5*4*3*2*1=40,320
  • 11!=39,916,800

So:

C=\frac{39,916,800}{6*40,320}

C= 165
