Hello!
If we try and use 50 coupons for the existing members, and the problem states that they gave FOUR times more than that to potential members, and 250 being our max, then:
250-50= 200
50x4=200—-> then add existing members to get back to the original number
So that means that they gave 50 coupons to existing members.
Step-by-step explanation:
slope = y2 - y1
__________
x2 - x1
slope = (-10 -2) / (-16 - 4)
slope = -12/-20
slope = 3/5
Answer:
Cube 1
Step-by-step explanation:
Volume of cube 1
V = 25*25*25 = 15625
Volume of 2 cubes
V = 24*24*24 = 13824
V =7*7*7 =343
V total = 14167
The total volume is greater for the 1 cube
Answer:
The inverse of the function is;
x = (y + 2)/3
Step-by-step explanation:
Here in this question, we shall be calculating the inverse of a function.
The function is;
y = 3x - 2
Firstly, let w = x;
y = 3w -2
y + 2 = 3w
w = (y + 2)/3
Now replace w by x
x = (y + 2)/3
This is the inverse of the function
Given:
The polynomial function is
Yuri thinks that 
is a root of the given function.
To find:
Why cannot be a root?
Solution:
We have,
If is a root, then the value of the function at is 0.
Putting 
in the given function, we get
Taking LCM, we get
Since the value of the function at is not equal to 0, therefore, is not a root of the given function.
