Mathematics
1 answer:
Anna35 [415]3 years ago
4 0

Answer:

-2

Step-by-step explanation:

1. Distribute: -3x + 6x + 3 = x-1

2. Combine like terms: 3x + 3 = x-1

3. Subtract 3 on both sides: 3x = x-4

4. Subtract x on both sides: 2x = -4

5. Divide each side by 2: x = -2

6. Check by plugging in -2 to the equation:

2. In the 2016 presidential election, most Americans were inundated with poll results, all of which reported a margin of error.
Fiesta28 [93]

Answer:

Throughout the clarification segment elsewhere here, the definition including its query is mentioned.

Step-by-step explanation:

  • The error margin applies to the difference between the results of this survey as well as the real estimates.
  • This may occur for several factors, such as limited sample size, incomplete survey, people's biased answers, etc.
  • It shows us where the outcomes of this study are not reliable and 100% right and, for several different reasons, there seems to be a disparity between some of the published and real statistics.

In addition to making audiences and people believe that perhaps the recorded results could not be considered as 100 percent reliable so there's still a variety of errors throughout themselves, it is important to incorporate this detail in polling data.

Hey I need help with this one question I don’t understand it
Eddi Din [679]

Answer:

y= -x-6

Step-by-step explanation:

slope intercept is as follows

y=mx+b

where m is the slope and b is the y intercept (where the line crosses the y axis)

We can see that the x intercept is -6 which means our equation so far is            y=mx-6 and so we just need the slope

To find the slope I will use the slope formula

To use the slope formula you will need two points on the graph. I am going to pick the y intercept and the point next to it

Which means our two points are

(0,-6) and (1,-7)

The slope formula is as follows

(y₂-y₁)/(x₂-x₁)

Plug in our values and get

(-7-(-6)/(1-0)

-1/1

-1 is our slope

which means our final equation is

-x-6
