Answer:
The diameter of the circle = 10 cm
The radius of the circle= 10/2= 5 cm
Step-by-step explanation:
Area of the circle = pi r^2
= pi 5^2
=3.14 *25
= 78.5 cm ^2
 
        
             
        
        
        
 Which inequality represents this situation ?

Hello there! 
How do you find the y-intercept? 
Answer: To find the y-intercept, substitute in 0 for x and solve for y 
y = x² + 3x + 5 
y = (0)²  + 3(0) + 5 
y = 0 + 0 + 5 
y = 5 
Thus, the correct answer is option D (0,5) 
I really hope this answer is clear enough for you to understand. If you have questions about the answer, please let me know. 
As always, I'm glad to be your helper this evening~!

Hello,
The line passes through (-1,3) and (9,11)
slope=(11-3)/(9+1)=8/10=4/5
y-3=4/5(x+1)
==>y=4/5 *x +19/5
