Which ordered pair is a solution to the graphed inequality?

Answers

Answer 1

Given:

The graph of a system of inequalities.

To find:

The ordered pair which is a solution to the graphed inequality.

Solution:

The boundary lines are:

[tex]x-2y=4[/tex]

[tex]2x-y=4[/tex]

From the given graph it is clear that only point (3,1) lies in the shaded region.

Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.

point (0,-1) does not belong to the shaded region.

Therefore, the correct option is A.

A water tank already contains 56 gallons of water in Baxter begins to fill it. water flows into the tank at a rate of 8 gallons per minute. write a linear equation to model this situation. Find the volume of the water in the sink 5 minutes after Baxter begins filling the tank.

Answers

Answer:

Equation: y = 8x + 56

After 5 minutes, the volume of the water was 96 gallons

Step-by-step explanation:

Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.

Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.

There are already 56 gallons of water in the tank, so b will be 56.

Plug in these values into the equation:

y = 8x + 56

So, the linear equation is y = 8x + 56

Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:

y = 8x + 56

y = 8(5) + 56

y = 40 + 56

y = 96

So, after 5 minutes, the volume of the water was 96 gallons

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2

Answers

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

PLZZ help im confused Scientists looking for a repressor of the androgen receptor (AR)-mediated transcription gene discovered a protein, Ankrd1. ARs were observed to bind to Ankrd1 and, in cells where Ankrd1 was over-expressed, AR-mediated transcription was inhibited. The scientists also detected lower levels of ARs when Ankrd1 was overexpressed using chromatin immunoprecipitation (ChIP) and Ankrd1 was not detected by ChIP.Based on these observations, which of the following conclusions would the scientists most likely draw?A. Ankrd1 is binding to ARs and preventing ARs from binding to the promoter, which inhibits mRNA transcription B. Ankrd1 is binding to the promoter and blocking ARS from binding, which prevents transcription of AR- mediated genes. C. Ankrd1 is binding to multiple sites and causing DNA to loop, preventing ARS from binding and activating gene transcription D.
