Answer:
x² + y² = 4²
Step-by-step explanation:
The standard equation of a circle centered at the origin and with radius r is
x² + y² = r²
Note that the point (4, 0) is 4 units horizontally and to the right of the center (0, 0). Thus, we know immediately that the radius is 4.
Thus the equation of this circle is x² + y² = 4²
Answer:
The solution is given below:
Step-by-step explanation:

As we know the value of k and r so the equation will be





9514 1404 393
Answer:
y = 0
Step-by-step explanation:
Subtracting the right side gives ...

The factor multiplying y cannot be zero, so y must be zero.
The x axis is labeled as Number of days.
<h3 /><h3>What is graph?</h3>
Graph is a mathematical representation of a network and it describes the relationship between lines and points.
let x be the number of days and y be money.
So, the equation is
y = -7x + 150.
Hence, the x axis is labeled as Number of days.
