I hope this helps. Use the formula: 4•3.14 (pi) •9 squared
Graphically: graph your equations and look for the intersections (these are your answers).
Algebraically: set your equations into y = format (below) and plug your values into the quadratic formula.
y = ax^2 + bx + c
(example: y = 2x^2 + 5x + 6; a = 2, b = 5, c = 6)
Answer: 25 ounces of yogurt
Step-by-step explanation:
Blueberries to Yogurt
2 to 5
10 to ?
The original ratio is 2 ounces of blueberries and its now 10 ounces. We got ten ounces by multiplying 2 by 5. To get the ounces of yogurt, you have to also multiply by 5.
5 x 5 = 25
So the ratio of blueberries to yogurt is now, 10 to 25.
Hope this helped!

Answer:
Step-by-step explanation:
First, you want to simplify so the equation would be x+2≤6 or x≤4
Because you are solving for x you want to graph a vertical line on 4.
Then you shade on the left side of the line because it is less than or equal to. If it were just less then you would do a dashed line on 4 but because it is also equal to 4 then you keep it a solid line.
I recommend using Desmos graphing calculator.
