Oksana_A [137]2 years ago
5 0

Answer:

1. 2x - 5

2. 5(x + y)

3. (5 - x)²

Step-by-step explanation:

1. Five less than the twice the number

Let the number be 'x'. 5 less than twice the number = 2x - 5

2. Five times the sum of two numbers

Let the two numbers be 'x' and 'y'. Then the notation would be: 5(x + y)

3. The difference of 5 and a number, squared

Let the number be 'x'. The mathematical expression for the above statement would be: (5 - x)².

A committee consisting of 3 faculty members and 5 students is to be formed. Every committee position has the same duties and vot
Lemur [1.5K]

Answer:

In 16170 ways the committee can be formed.

Step-by-step explanation:

3 faculty members and 5 students are required to form a committee.

The eligible to serve on the committee are 7 faculty members and 11 students.

If each committee position has the same duties and voting rights.

Then, the number of ways of selecting 3 faculty members out of 7 eligible faculty members is ^7C_{3} = 35.

Again, the number of ways of selecting 5 students out of 11 eligible students is given by ^{11}C_{5} = 462.  

Therefore, in (35 × 462) = 16170 ways the committee can be formed. (Answer)

The table below relates the number of rats in a population to time in weeks. Use the table to write a linear equation with w as
salantis [7]

Answer:

C(w) = 6w + 9

Step-by-step explanation:

Anytime 0 is given somewhere, it should be given close scrutiny. In an equation whose general form is

y = mx + b

0 will determine the y intercept immediately.

So when x = 0, y will equal

y = 0*m + 9

So b = 9

y = mx + 9 Now we need to find m

I should start using your variables.

C(w) = m*w + 9

when w = 3 then C(3) = 27

27= 3m +9

27-9 =3m + 9 -9

18 = 3m

18/3 = 3m/3

x = 6

So the complete equation is

C(w) = 6w + 9
