Answer:
The answer is x=9 so, its option 3.
Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, 
Period is
divided by the coefficent of x, in this case, 
Phase shift, is how much you sum or subctract from x inside the sine, in this case
.
Midline you get by hiding the sine and reading what's left, in this case, -4.
4y=-20+3x and 4y=13.6x-20
so
-20+3x=13.6x-20
3x=13.6x
3=13.6 so it is wrong and system doesn’t have solution
Answer:
Option A.
Step-by-step explanation:
Area of a square is
.... (1)
where, x is side length.
The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.

It is given that bob currently owns 250,000 square feet of land.
Fist find the length of each side.


Taking square root on both sides.

Differentiate with respect to t.

Substitute x=500 and
in the above equation.


Farmer bob is losing 2,000 square feet of land per year.
Therefore, the correct option is A.
7/8 + 7/12 = 35/24 = 1 11/24
