Answer:
the class has 12 girls and 16 boys what is the ratio of the total students to boys in simplest form
Correct it is right u have to multipl
Answer:

Step-by-step explanation:
Here we can see that the parent function is
and the translated function is g(x). f(x) is a parabola.
Rule says that any factor if multiplied by f(x) is going to contract the graph towards the y axis and vice versa.
Similarly any factor if f(x) is divided by some factor it is going to be stretch the graph away from the y axis and vice versa.
Here we can see that the translated graph g(x) is stretched away from the y axis with reference to the parent function f(x). Hence as per he rule discussed above, we get a preliminary information that the parent function f(x) is being divided by some factor.
now we are given that


Where as
{as given in the graph}
Hence
at x=3 , f(x) = 9 and g(x) = 1 , and also we have discussed above that f(x) is divided by some factor. Hence 

Answer:
f(- 2) = 13
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x)
f(- 2) = - (- 2)³ + 2(- 2)² + (- 2) - 1
= - (- 8) + 2(4) - 2 - 1 = 8 + 8 - 2 - 1 = 13
Answer:
a = 5
b = -4
c = -20
Step-by-step explanation:
Here, we want to express the given equation in the following form;
So we can have this as;
5x-4y-20 = 0
That means we have;
a as 5
b as -4
and c as -20
