Answer:
20
Step-by-step explanation:
In area you have to multiply so 10 x ? = 200
10 x 20 = 200
5x = 4y - 3
The correct answer is D. 5x - 4y = -3
This is because standard form is the form ax + by = c, where a, b, and c are coefficients or constants of the variables x and y. Thus, Answer D (above) is the correct answer to this problem, as it is the only option that fits this.
Answer:

Step-by-step explanation:
The exponential function that decrease by 15% every time x increases by 1 is given by:

We simplify the parenthesis to get:

Therefore the decrease by 15% every time x increases by 1 is

The second choice is correct.
