Answer:

$\sf 3\left[-x+\left(2x+1\right)\right]=x-1$

$\sf 3\left(-x+2x+1\right)=x-1$

Combine like terms:

$\sf -x+2x=x$

$\sf 3\left(x+1\right)=x-1$

Expand:

$\sf 3x+3=x-1$

Subtract 3 from both sides:

$\sf 3x+3-3=x-1-3$

$\sf 3x=x-4$

Subtract x from both sides:

$\sf 3x-x=x-4-x$

$\sf 2x=-4$

Divide both sides by 2:

$\sf \cfrac{2x}{2}=\cfrac{-4}{2}$

$\boxed{\boxed{ \sf x=-2}}$

NARA [144]

Answer:

A. The data are continuous because the data can take on any value in an interval.

Step-by-step explanation:

The data surveyed is the exact mass, in grams, of food eaten by each person each day.

This type of data is continous, not discrete. The mass can take any value within the domain of positive real numbers. It represents a physic variable, and they are always continous.

find the equation of the line that is parallel to the line Y equals 3X -6 and passes through the points (1 -8). Write the equa

AlladinOne [14]

<h3>hello!</h3>

=====================================================

Parallel lines have the same slope.

So if the given line has a slope of 3, then the line parallel to it has the same slope (3)

Now, let's write the equation of the line in Point-Slope Form.

Remember, point-slope form looks like so:-

$\bigstar{\underline{\boxed{\pmb{y-y1=m(x-x1)}}}$

Where

y₁ is the y-coordinate of the point that the line passes through

m is the slope

x₁ is the x-coordinate of the point that the line passes through

In this case,

y₁ is equal to -8

m is equal to 3

x₁ is equal to 1

Plug in the values:

$\longrightarrow\sf{y-(-8)=3(x-1)}$

Simplify:

$\longrightarrow\sf{y+8=3(x-1)}$

and we're done!

=========================================================

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
