24 degrees if ur decreasing
<span>N + D = 55 coins (1) (N stands for nickels,
5N + 10D = 390 cents (2) D stands for dimes)
Simplify (2) by canceling the factor 5 in both sides:
N + 2D = 78 (3)
Subtract eq(1) from eq(3). You will get
D = 78 - 55 = 23.
Answer. 23 dimes and 55-23 = 32 nickels.
Check. 23*10 + 32*5 = 390 cents</span>
Area = 1/2pi•r^2
1/2pi•9^2= 127.23 cm^2
Answer:
We can express the equation for any linear equation with slope -2 and point (x0,y0) as:

Step-by-step explanation:
Incomplete question:
There is no point to complete the equation.
As we have no point to complete the linear equation, we will solve for any given point (x0,y0) and a slope of m=-2.
The linear equation can be written generically as:

If a point, like (x0,y0) belongs to the linear equation, it satisfies its equation. Then:

Then, we can calculate b as:

We can express the equation for any linear equation with slope -2 and point (x0,y0) as:
