The graph of the equation y − 1 = −2(x − 2) contains which set(s) of ordered pairs? Select all that apply.
Mila [183]

Answer:

OPTION B.

OPTION C.

Step-by-step explanation:

Given the equation of the line:

y - 1 = -2(x -2)

We can substitute the coordinates of each set of ordered pairs into the equation in order to know which belong to the graph of that equation:

A. (0, -2)\ and\ (1, 3)

Substituting into the equation these coordinates:

x=0\\\\y=-2

We get:

-2 - 1 = -2(0 -2)\\\\-3\neq 4

The graph of the given line does not contain this set of ordered pairs.

B. (0, 5)\ and\ (-2, 9)

Substituting into the equation these coordinates:

x=0\\\\y=5

We get:

5 - 1 = -2(0 -2)\\\\4=4

Substituting into the equation the coordinates of the other ordered pair:

x=-2\\\\y=9

We get:

9 - 1 = -2(-2 -2)\\\\8=8

<em> The graph of the given line contains this set of ordered pairs.</em>

C. (-1, 7)\ and\ (2, 1)

Substituting into the equation these coordinates:

x=-1\\\\y=7

We get:

7- 1 = -2(-1 -2)\\\\6=6

Substituting into the equation the coordinates of the other ordered pair:

x=2\\\\y=1

We get:

1 - 1 = -2(2 -2)\\\\0=0

<em>The graph of the given line contains this set of ordered pairs</em>

D. (3, -1)\ and\ (2, -1)

Substituting into the equation these coordinates:

x=3\\\\y=-1

We get:

-1 - 1 = -2(3 -2)\\\\-2=-2

Substituting the other ordered pais (2, -1):

-1 - 1 = -2(2 -2)\\\\-2\neq 0

The graph of the given line does not contain this set of ordered pairs.

What logarithmic equation has the same solution as x-4=2^3
kumpel [21]

What logarithmic equation has the same solution as x-4=2^3

Solution:

x-4=2³

x-4=2*2*2

x-4=8

TO solve for x, Let us add 4 on both sides

x-4+4=8+4

x+0=12

So, x=12

But, x=12 is not a logarithmic equation and there are no options

So, an equation like, x=㏒ 10^{12}

As log has base 10,

So, x=㏒ 10^{12}=12

So, logarithmic equation like x=log 10^{12} has same solution as x-4=2³
