Answer: y=2x-7

explanation:
y-1=2(x-4)
y−1=2x−2·4
y−1=2x−8
(y−1)+1=(2x−8)+1
y−1+1=2x−8+1
y=2x−7

The functions f(x) and g(x) are described below: f(x) = 7x + 9 g(x) = 7x −4 The graph of g(x) is obtained by shifting down the g
Slav-nsk [51]
Correct Answer:
Option A

Solution:

f(x) = 7x + 9
g(x) = 7x - 4

We can re-write g(x) as:

g(x) = 7x + 9 - 13

Since 7x+9 is equal to f(x), we can write:

g(x) = f(x) - 13

This relation shows that g(x) is obtained by shifting f(x) 13 units vertically down. So the correct answer is option A.

yuradex [85]

Answer:

y-coordinate is 5 or -1.

Step-by-step explanation:

Point A is at (x, 2) and B is at (x+6, 2). Since AB must lie on the line y=2  and be 6 units long. Point C is on the line x = -3 . So let C be at (-3, y).

Since ΔABC is a right angle, then point C must have the same x-coordinate as point A. Therefore, A(-3, 2) and B(2, 2).

The area of ΔABC is 6. So,

9 = 1/2 (b)(h)

where b is the base and h is the height.

so b = 6 and h = AC

Solving this for C gives

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

9 = 1/2 (6)(AC)

18/6 = AC

3 = AC

Point C must lie 3 units above point A or 3 units below the point A. If it lies 3 units above, then it has a y-coordinate of 2 + 3 = 5.

If it lies 3 units below, it has a y-coordinate 2 - 3 = -1.

Therefore, y-coordinate is 5 or -1.

Identify the two events described in the study and determine if the results indicate that the events are independent or dependen
Monica [59]

Answer:  B. Being around cigarette smokers and developing heart disease .

C. Independent. Being around cigarette smokers does not cause heart disease.

Step-by-step explanation:

Given : A study found that there is no relationship between being around cigarette smokers and developing heart disease.

i.e. The two events here are Being around cigarette smokers and developing heart disease .

Since there is no relationship between the above two events.

Being around cigarette smokers does not cause heart disease.

It means that the two events are not dependent on each other i.e. they are independent.
