The regression line will be y = 20.64 - 0.3038x.

<h3>How to explain the regression?</h3>

It should be noted that regression is a statistical method that determine the relationship between the variables.

Here, the regression line will be y = 20.64 - 0.3038x. The slope coefficient is -0.03038 and the intercept is 20.460.

The slope coefficient defines that for a unit increase in the percentage of vacancy rate will reduce 0.3038 unit of monthly office rent.

Please help fast<br> The graph shows the function f(x)
DedPeter [7]

Answer:

3/1

Step-by-step explanation:

The average rate of change is the distance between y values divided by the distance between x values. We know this as rise/run or slope for linear equations. For non-linear equations, we calculate the average over an interval.

This function has y-values of -1 at x=0 and 5 at x=2.

We add -1+5=6 and divide this by 2-0=2.

6/2=3.

The y-values on average change 3 units for every 1 unit of the x-values.

Missy did this work to solve an equation. Did she make an error?
STatiana [176]

Answer: yes, she did made an error, a very big mistake.

Step-by-step explanation:

first, we have varieties of ways in which we can use to solve this, the most important thing is to stick to the mathematical rules of solving any equations.

using the most simpler method

-4x + 11 = 6x + 1

collect like ter

-4x -6x = 1 - 11

-10x = -10

divide bothside by -10

-10x/-10 = -10/-10

x=1

secondly, using the method she is intending to use, its more easier to subtract 6x from bothside

-4x + 11 = 6x +1

-6x -6x

_______________

-10x + 11 = 1

-10x = 1-11

-10x = -10

x = 1

or still we can doing it exactly as she did, but it will take us through a long way i.e by adding +6

-4x + 11 = 6x + 1

+6x +6x

_______________

2x +11 = 12x +1

2x-12x = 1-11

-10x=-10

x=1

4(x + 2) = 2x + 10<br><br><br> explain each step plz
Ugo [173]

Answer:

x=1

Step-by-step explanation:

4(x + 2) = 2x + 10

Distribute 4(x+2).

4x+8 = 2x + 10

Subtract 2x and 8 from both sides.

4x-2x=10-8

2x=2

Divide both sides of the equation by 2.

\frac{2x}{2} =\frac{2}{2}

x=1

Find the solution to the systems. x+y=1 and 3y=-3x+3
jenyasd209 [6]

Answer:

infinite number of solutions

Step-by-step explanation:

x+y=1

3y=-3x+3 ⇒ y=-x+1 ⇒ y+x=1

both equations are the same, so they have infinite number of solutions
