Answer:
none of the above
f(x) ≈ 197·1.03^x; approximately 3% daily
Step-by-step explanation:
If we let x represent days, then x/7 represents weeks and we can rewrite f(x) as ...
f(x/7) = 197·1.25^(x/7) = 197·(1.25^(1/7))^x
f(x) ≈ 197·1.03^x
__
The daily multiplier of 1.03 represents a daily growth rate of
1.03 -1 = .03 = 3%
_____
These answers are not found among the offered choices:
f(x) = 197·1.03^x
3% daily growth
Step-by-step explanation:
Just substitute any number for one variable to find the value of the other.
Eg:
2x-y=11
2(1)-y=11
2-y=11
-2 -2
-y=9
-y/-1=9/-1
y=-9
So (1,-9) is a solution to the equation.
Follow the steps and find many more solutions.

Answer: <em>Yes</em>, a coefficient can have two variables.
Area Of Rectangle
= 2 length × 2 width
= 2 l + 2 w
l = 2 w -3................equation (i)
2 l + 2 w = 42..........equation (ii)
2(2 w -3) + 2 w =42
4 w - 6 + 2 w = 42
4 w + 2 w = 42 + 6
6 w = 48
w =8
l = 2 w - 3
l = 2×8 - 3
l = 13
Length = 13
Width = 8
