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
This is what I would write
Y=34x+(-7) tho this is in y=Mx+b form so I hope this helps
4x - 3y =5
3y = 4x - 5
y = 4/3 x - 5/3
Equation of the line passing through the point (-6,3) and parallel to L
a) Parallel lines have same slope so slope = 4/3
y - 3 = 4/3(x + 6)
y - 3 = 4/3 x + 8
y = 4/3 x + 11
Answer:
Equation y = 4/3 x + 11
b) Perpendicular lines, slope is opposite and reciprocal so slope = -3/4
y - 3 = -3/4 (x + 6)
y - 3 = -3/4 x - 4.5
y = -3/4 x - 1.5
Answer:
Equation y = -3/4 x - 1.5
Hello,
If the rate of return on an investment was 3% and the inflation rate was also 3%, then your buying power would remain the same. The two equal values would cancel each other out.
Imagine being given $300 and than having to pay $300, you are back where you started.
Good luck,
MrEQ
