Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)? (–4, 0) (–2, 0) (0, 2) (4, –2)
son4ous [18]
<span>f(x) = (x – 4)(x + 2),
x-intercept means that f(x) = 0.

0 = (x-4)(x+2)
(x-4)=0, x= 4, point (4,0)
(x+2)=0, x = -2, point (-2,0)

This graph has 2 x-intercepts:  (4,0) and (-2,0).

From given answers we can choose only </span>(-2,0).

Q1 [5]
ValentinkaMS [17]

Answer:

The required drawing showing the cliff, river, and tower as well as the details in the question is attached, please find alongside the answer

The width of the river is approximately 51.55 meters

Step-by-step explanation:

The height of the observation tower = 11 meters

The angle of elevation of the cliff top and the opposite side of the river = 20°

The angle of elevation of the tower top and the opposite side of the river = 30°

Therefore, by sine rule, we have;

h/sin(20) = w/sin(60)

11/sin(10) = length, l/sin(60)

l = sin(60) ×11/sin(10) ≈ 54.86 meters

w = l × cos (20) = 54.86 meters × cos (20) ≈ 51.55 meters

The width, w, of the river is approximately 51.55 meters.

Solve the following inequality for y<br> y/3 - 7 ≥ 2/3
astra-53 [7]

Answer:

y≥ 23

Step-by-step explanation:

y/3 - 7 ≥ 2/3

Add 7 to each side

y/3 - 7+7 ≥ 2/3+7

y/3  ≥ 2/3+21/3

y/3  ≥ 23/3

Multiply each side by 3

y/3 *3 ≥ 23/3*3

y≥ 23

The graph of a function f(x) is shown below:
Tom [10]
Count the dots plotted here.  There are four of them, right?  What are the x-coordinates of those four dots:  Answer:  {-1, 0, 1, 2}.  

Reject answers B and C because none of the four dots have x-coordinate -3.
Reject answer A because this set would not include x=-1 or x=2.
