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.
Answer:
yes

if it is a terminating decimal(a decimal that ends) it will be rational
Hey try using cymatn.com !!!
Answer:
x=5.5
Step-by-step explanation:
We can solve this equation by using the various properties and PEMDAS.
First, we would want to subtract 18 on both sides, to even out the equation.
The result is -7x=-38.5
Now we can isolate the x by dividing both sides by -7.
-38/-7=5.5
Thus, x=5.5
Hope this helps!
