Given functions are


The total number of ducks and swans in the lake after n months can be determined by adding the functions s(n) and d(n).





Taking 2 as common, we get

Hence The total number of ducks and swans in the lake after n months is
Answer:
y=11
Step-by-step explanation:
3y=y+22
3y-y=y-y+22
2y=22
y=11

Answer:
y-intercept (0,11/5)
x-intercept (11/2,0)
Step-by-step explanation:
The y-intercept is obtained when the x-coordinate equals 0 (x=0)
so the y-intercept is (0,11/5)
The x-intercept is obtained when the y-coordinate equals 0 (y=0)
In this case
0 = -(2/5)x+11/5---->(2/5)x = 11/5 ----> x=(5*11)/(5*2) = 11/2
So the x-intercept is (11/2,0)
The height of Ernies shadow is 4 feet when his height is 6 feet.
<h3>
equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the length of his shadow. Given that the ratio of ernie's height to his shadow's height is 1.5 to 1. Hence:
- (1.5/2.5) * y = 6
- y = 10 feet
(1/2.5) * 10 = x
x = 4 feet
The height of Ernies shadow is 4 feet when his height is 6 feet.
