Answer:
what
Step-by-step explanation:
The function is given by
y=45,200 + 1,900x
and is of the form y = mx+b , where m is the rate of change and b is the fixed value ( or we can say initial value)
Now when we compare we get m = 1,900 for our problem .
So the population increases every year by 1,900.
Answer:
x=3 and y=4
Step-by-step explanation:
solve x-y=-1 to get x:
x−y=−1
x−y+y=−1+y(Add y to both sides)
x=y−1
Substitute y−1 for the x value in x+2y=11:
3y/3=12/3
y=4
Substitute 4 for the y value in x=y−1:
x=y−1
x=4−1
x=3
so y=4, and x=3
