Answer:
Step-by-step explanation:
y - 9 = 3(x - 0)
y - 9 = 3x - 0
y = 3x + 9
Answer:
Step-by-step explanation:
slope=m=(Y2-Y1)/(X2-X1)
As given values
take, (X1,Y1)=(-7,-4)
(X2-Y2)=(8,8)
hence X1=-7 , Y1= -4 , X2=8 , Y2= 8
putt the values in the above equation of slope we get ,
m=(8-(-4))/(8-(-7)
m=12/15 Ans
Answer:
![x^{2} +y^{2}=25](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2By%5E%7B2%7D%3D25)
Step-by-step explanation
The standard equation of a circle centered at origin is ![x^{2} +y^{2} =r^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2By%5E%7B2%7D%20%3Dr%5E%7B2%7D)
r = radius of the circle
The circle is passing through the point (0,5)
∴ radius ![r=\sqrt{(0-0)^{2}+(5-0)^{2} }](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B%280-0%29%5E%7B2%7D%2B%285-0%29%5E%7B2%7D%20%7D)
![r=\sqrt{0+25}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B0%2B25%7D)
![r=\sqrt{25}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B25%7D)
![r^{2}=25](https://tex.z-dn.net/?f=r%5E%7B2%7D%3D25)
∴ The equation of the circle is
![x^{2} +y^{2} = 25](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%2By%5E%7B2%7D%20%3D%2025)
The given graphs model exponential functions are a, b and c.
Option a, b and c are the correct answers.
To choose the graph.
<h3>What is exponential function?</h3>
A relation of the form y = ax, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.
Given that:
The three graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.
The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.
Therefore, the given graphs a, b and c are the correct answers.
