Answer with explanation:

To know the use of Computer Lab in the School

      A Survey has been done.Out of the four Question asked,

The education of the trainer in the computer Lab does not come into consideration,to know the use of computer lab in the school, the use of computer lab can be known only by whether students are getting well versed with Computer and it's applications or not.

Number of Learning Stations in the computer lab, also can't tell the use of computer Lab in the school, because we have to check knowledge of the students about computers to know the better use of the Lab.

So, number of Class projects, or in my own words A test on computer awareness and It's software tools will be a better survey Question.

Option D is the question in the survey is a STATISTICAL QUESTION.

       (D) How many class projects did you complete using the computer lab?

Write many equations that are equal to the equation 2x+4=x-4.
Jobisdone [24]

Answer:

<u>x = -8</u>

4x + 8 = 2x - 8

3x + 4 = 2x - 4

2x + 16 = x + 8

x - 1 = 2x + 7

17x + 36 = 16x + 28

13x + 2 = 12x + 11

.......

(this is infinite)

As long as it cancels out to x = -8

Need help and will be giving Brainliest
Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

Step-by-step explanation:

hope it helps
