Answer:
Nancy gastó 8,58 dólares.
Step-by-step explanation:
Para calcular cuánto dinero gastó Nancy, debemos hallar la relación entre Nancy y María, tal como sigue:
(1)
En donde M es por María y N por Nancy
En la relación de la equación (1) tenemos que el dinero que gastó María es 3 veces lo que gastó Nancy, tal como dice el enunciado.
Entonces, podemos hallar ahora cuánto gastó Nancy:

Por lo tanto, Nancy gastó 8,58 dólares.

Perpendicular.
Parallel lines will have the same slope (1/6 and 1/6 or -6 and -6)
Perpendicular lines will have opposite reciprocal slopes. (1/6 and -6)
we have

Equate the function to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side.


the factorization is equal to

therefore
<u>the answer is</u>

If f(8)=4 that means that if you plug 8 on as x in whatever the equation of f is you will get 4 as answer therefore (8,4) is a point on the graph
Answer:
axis of symmerty = x coordinate of vertex = -b/2a
-6/2 = <u>-3 = x</u>
<u />
vertex = (-3,y)
-3^2 +6(-3)
9-18 = -9 = y
<u>(-3,-9) = vertex</u>
