Answer:

2x-y=-1

Step-by-step explanation:

y + 9 = 2(x + 5)

y + 9 = 2x + 10 [distribute]

y = 2x + 1 [subtract 9 from both sides]

y - 2x = 1 [subtract 2x from both sides]

-2x + y = 1 [put x first]

2x - y = -1 [multiply by -1 to make x coefficient positive]

Find the range of the function: f(x) = x + 3, for x ≠ 1

Tju [1.3M]

Answer:

All Real Numbers except for 4

Step-by-step explanation:

Objective: Specify domain and range of a function.

The equation is a linear equation. A linear equation range is all real numbers. However x cannot equal 1 so let plug in x to find where the y value CANT be.

$f(1) = 1 + 3 = 4$

So the range is

All Real Numbers except for 4.

First term f = 1

If first four terms are f, f + d, f + 2d, f + 3d

f + f + d + f + 2d + f + 3d = 100

4f + 6d = 100 (divided by 2 , both sides )

2f + 3d = 50

2 + 3d = 50

3d = 50 – 2

3d = 48

d = 48/3

d = 16

The arithmetic sequence is 1, 17, 33, 49, ………….
