Answer:

  • y-intercept: y=9
  • zeros: x= -3, -1, 1, 3

Step-by-step explanation:

The y-intercept is where the graph crosses the y-axis. On this graph, that is just below y=10. A reasonable estimate* of the y-intercept is y=9.

__

The zeros are those places on the graph where y=0. The line y=0 is the x-axis, so the zeros are the x-values of the places where the graph crosses the x-axis. Those points are clearly labeled: x = -3, -1, 1, 3.

_____

* Knowing the zeros, you can write a factored-form equation for the graph:

  y = (x +3)(x +1)(x -1)(x -3)

You can substitute x=0 in this equation to see what the y-intercept would be:

  3×1×-1×-3 = 9

That is, with no scale factor applied to the function, its y-intercept would be 9. This is the same value we estimated above, so it is reasonable to assume that value is correct.

Simplify (4x − 6) + (5x + 1). 9x + 5 9x − 5 x − 5 −x − 5
azamat

Answer:

9x - 5  

Step-by-step explanation:

<u>Simplify:</u>

  • (4x − 6) + (5x + 1) =        ⇒ opening parenthesis
  • 4x - 6 + 5x +1 =              
  • (4x+ 5x) + (1 -6) =           ⇒ grouping like terms
  • 9x + (- 5) =                     ⇒ simplifying like terms
  • 9x - 5                             ⇒ answer

<u>Correct choice:</u> B. 9x -5

Un edificio proyecta una sombra de 7.5m.mientras que un arbol que mide 1.6 m de altura proyecta una sombra 1.85 M¿Cual es la alt
sattari [20]

Answer: The height of the building is 6.49 meters.

Step-by-step explanation:

This can be translated to:

"A building projects a 7.5 m shadow, while a tree with a height of 1.6 m projects a shadow of 1.85 m.

Which is the height of the building?"

We can conclude that the ratio between the projected shadow is and the actual height is constant for both objects, this means that if H is the height of the building, we need to have:

(height of the building)/(shadow of the building) = (height of the tree)/(shadow of the tree)

H/7.5m = 1.6m/1.85m

H = (1.6m/1.85m)*7.5m = 6.49m

The height of the building is 6.49 meters.
