Answer:
None of the choices are correct.
Step-by-step explanation:
In order to correctly translate the sum of eight and twice "w" we have to remember that every time that an algebraic problem refers to twice something we have to multiply that by 2, so the sum of eight and twice W should look like this:
So since that is not in the options, none of the options are correct.
Answer:
Step-by-step explanation:
we know that
The roots of the quadratic function (x-intercepts) are
x=-1 and x=5/3
so
we can write the equation of the parabola as
where
a is a coefficient
Remember that
The parabola pass through the point (5,40)
substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a
x=5, y=40
substitute
apply distributive property
see the attached figure to better understand the problem
