Use related facts to determine whether the given value is a solution for each equation
solong [7]
For these questions it's asking you to substitute the value into the equation.
For example question 5 says,
26= y-9;y=35
basically it's saying if y=35, is the equation correct or not.
In this case: 26= 35 -9 is correct.
So your answer is true.
Hope this helps Xx

The graph is touching the x-axis at x= 2 and is turning away.

When a graph exhibit such a behavior at a root, we say that the multiplicity of the root is 2. So the roots of the polynomial are x = 2 and x = 2. The factors of the polynomial are (x - 2) and (x - 2)

The polynomial thus can be written as product of its factors as (x-2)(x-2)

So the correct answer to this question is option B
