Answer:
y= 2/3x +1
Step-by-step explanation:
The y intercept is 1 It crosses the y axis at 1. So the point is (0,1)
Another point on the line is (3,3)
We can calculate the slope
m = (y2-y1)/(x2-x1)
= (3-1)/(3-0)
=2/3
The equation for a line is y=mx+b where m is the slope and b is the y intercept
y= 2/3x +1
Answer: Infinitely many solutions.
Step-by-step explanation:

Use
for y in 

Infinitely many solutions.
Answer:
y = ( x − 2 ) ^ 2 + 3
y = x^2 − 4x + 7
Step-by-step explanation:
y = a ( x − h ) ^ 2 + k
where vertex is (h,k) = (4,-1)
h=4, k=-1
y = a ( x − 4 ) ^ 2 - 1
sub ( 2,3 )
3 = a (2 - 4)^2 - 1
a=1
y = 1 ( x − 2 ) ^ 2 + 3
y = ( x^2 − 4x + 4 ) + 3
y = x^2 − 4x + 7
There are 83210 subscribers after 5 days
<h3>How to determine the number of subscribers?</h3>
The given parameters are:
- Initial, a = 93000
- Rate, r = 2.2%
The number of subscribers each day is calculated as:
f(n) = a * (1-r)^n
This gives
f(n) = 93000 * (1 - 2.2%)^n
Evaluate the difference
f(n) = 93000 * 0.978^n
At 5 days, we have:
f(5) = 93000 * 0.978^5
Evaluate
f(5) = 83210
Hence, there are 83210 subscribers after 5 days
