Answer:
2/(7a) < x < 7
Step-by-step explanation:
The product of roots of ax² +bx +c is c/a. In this case, that means the second root of the equation is ...
... 2/(7a)
Since a < 0, the parabola opens downward and 2/(7a) < 0. The quadratic function will be positive between the two roots, on the interval ...
... 2/(7a) < x < 7
Answer:
66 I am pretty sure
Step-by-step explanation:
6 x 2 divided by 2 = 6
6 + 6 = 12 x 10 divided by 2 = 60
add them together
60 + 6 = 66
Answer:
9a + 18
Step-by-step explanation:
so the first step is to evaluate the value of f(2).

Now that we have this value we can use the slope formula (y2 - y1) / (x2 - x1) where y2 is f(a), y1 is 29, x2 is a, and x1 is 2

Now from here we can use long division to simplify it further

It is not because it is a whole number fractions are mixed numbers
