the bag of rice weighs 4.5 pounds
Multiply 4.5 with 16 oz (as 1 lb = 16 oz)
4.5 x 16 = 72.
The bag of rice has 72 oz of rice inside.
The recipe only needs 60 oz of rice ∴ True, you will have enough, with 12 oz left over.
hope this helps
You just find the quartiles which are 62 and 50 the mines them which equals 12.
The roots: this is when y=0, so in yours there are 2 roots. Just look at the x value when y=0 and that is your roots.
Y intercept- this is when x=0, so just look at the y value below x=0 and that is the y intercept. Note the answer will probably be in the form (0,_)
Vertex=do you see a pattern? Well the vertest would be the highest or lowest point of the quadratic equation. Your vertex would be (5,-9) because just look at x=4 and x=6, bit of the y values are -8 and when you look at x=3 and x=7 they are also the same because this is a quadratic equation.
Max or min: yours is a minimum because (5,-9) is the lowest point. Every value left and right of this are higher up the graph, so this would be a minimum.
*something that will help you see this all more clearly is if you graphed this or put it into Desmos to see the vertex etc.
