Answer:

{x}^{2}  - 14x - 49 = 0

{x}^{2}  - (7  + 7)x - 49 = 0

{x}^{2}  - 7x - 7x - 49 = 0

x(x - 7) + 7(x - 7) = 0

(x - 7)(x + 7) = 0

NOW,

x-7=0

or,x=7

And,

x+7=0

or,x= -7

THEREFORE, x= 7, -7

hope it helps you,

make me brainliest plz

Ilya [14]

Answer:

0,05

Step-by-step explanation:

1)First, Let’s find the mean of the data table

12 + 10 + 12 + 6 + 8 + 4 + 2 + 12 = 66

66 ÷ 8 = 8,25

2)12 - 8,25 = 3,75

10 - 8,25 = 1,25

12 - 8,25 = 3,75

6 - 8,25 = -1,75

8 - 8,25 = -0,75

4 - 8,25 = -3,75

2 - 8,25 = -5,75

12 - 8,25 = 3,75

3) 3,75 + 1,25 + 3,75 - 1,75 - 0,85 - 3,75 - 5,75 + 3,75 = 0,4

0,4 ÷ 8 = 0,05

2. Function C takes time for its input and gives a student's Monday class for its output.
kaheart [24]

Answer:

We know that C(T) is a function where you input the time T, and the output will be the student's Monday class.

a) A student has English at 10:00.

Here we can use T = 10:00 as the input, and the output will be the class, English.

Then this can represent this with:

C(10:00) = English.

b) Write a statement to describe the meaning of C(11:15) = chemistry.

for C(11:15) = Chemistry

The input, the time, is 11:15

The output, the class, is chemistry.

The student has a chemistry class at 11:15
