14x^2 + 37x + 5....Richard is designing a new website for students to create study groups and collaborate with other students.

Furkat [3]

Answers:
1) The constant of the polynomial expression represents the:
number of group members when the site launches

2) The binomial (1+7x) is a factor of the polynomial expression and represents the:
number of members per group after x months

Solution:
1) The estimate for the total number of groups members (y) is given by the polynomial expression:
y=14x^2+37x+5
where x is the number of months since the site's launch.

When the site launchs:
x=0→y=14(0)^2+37(0)+5=14(0)+0+5=0+0+5→y=5
The number of group members when the site launches is 5
And the problem says: "The site will launch with five study groups"

2) The site will launch with five study groups, each with its creator as its only member, then the number of members per group is 1.
Richard estimates that seven new members will be added to each study group every month (x), then:
The number of members per group after x months will be: 1+7x

Which of the following is an example of a valid use of the multiplication property of equality? A. to isolate s in the equation

marusya05 [52]

Answer:

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.

Step-by-step explanation:

We have a set of an example of equations; we need to study the use of multiplication property of equality.

A. to isolate s in the equation s – 4 = –12, divide both sides of the equation by.In this sentence, to isolate s we do not need multiplication only addition and subtraction.

B. to isolate s in the equation s – 4 = –12, multiply both sides of the equation by. In this sentence, to isolate s we do not need multiplication only addition and subtraction.

C. to isolate s in the equation –4s = –12, divide both sides of the equation by -4. This sentence is correct, and it uses division. However, we are studying multiplication property not division.

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1. Firstly, it is a good idea to change both negative signs to positive by multiplying by -1 to isolate s.

Finally, we can conclude that a valid use of the multiplication property of equality is D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.
