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:

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

The graph of the given line contains this set of ordered pairs.

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:

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

The graph of the given line contains this set of ordered pairs

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.

Mice and Pain Can you tell if a mouse is in pain by looking at its facial expression? A new study believes you can. The study1 c

kotykmax [81]

Explanation:

1. a) Null hypothesis: There is no statistically significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

b) Alternate hypothesis: There is a statistically-significant relationship between the mouse grimace scale and the amount of pain felt by mouse.

2. Yes, because a statistically significant data implies that there is sufficient evidence to believe the study, based on the results of the findings.

3. No, since the variables are different in this case. Here we are dealing with a non-painful solution so there may be no sample correlation as extreme as that found in the original study.

4. Possibly, because every hypothesis is an assumption until it is proven. Thus, in every statistical research, there may be different findings.

2a+6=12 what does a equal a=? Please help.

Rashid [163]

Answer:

Step-by-step explanation:

2a+6=12

Step 1: Subtract 6 from both sides.

2a+6=12

-6 -6

2a=6

Step 2: Divide both sides by 2.

2a/2=6/2

a=3
