Solve the equation for y
6у - 1.5х = 8

Answers

Answer: can it be a fraction?

Step-by-step explanation:

Answer: y = 4/3 + 1/4x

Step-by-step explanation: 6y - 1.5x = 8

Add 1.5x to get y alone, 6y = 8 + 1.5x

Divide everything by 6, y = 8/6 + 1.5x/6

Simplify, y = 4/3 + 1/4x

the mean mass of 6 boxes is 45kg. one of the boxes with a mass of 50kg is removed. calculate the new mean mass of the remaining boxes​

Answers

Answer: 6 boxes. average 45 each.

Step-by-step explanation:

The mean of a dataset if the average of the dataset.

The new mean mass of the remaining boxes is 44 kg

From the question, we have:

[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes

The mean of a dataset is:

[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]

So, we have:

[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]

Multiply by 6

[tex]\mathbf{45 \times 6= \sum x}[/tex]

[tex]\mathbf{\sum x = 270}[/tex]

One of the boxes is 50 kg.

So, the mass of the remaining boxes is:

[tex]\mathbf{Mass = 270 - 50}[/tex]

[tex]\mathbf{Mass = 220}[/tex]

The mean of the remaining boxes is:

[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]

[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]

[tex]\mathbf{\bar x = 44}[/tex]

Hence, the new mean mass of the remaining boxes is 44 kg

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the simplest form.

Answers

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the slope of linear functions using two points, we have the following equation :

[tex]slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\ [/tex]

Where a and b are two point of the function.

_________________________________

Step (2)

Well now I want to choose a name for the given points :

a = ( -3 , -3 ) ••••••••• b = ( -18 , -23 )

_________________________________

Step (3)

It's time to put the the coordinates in the above equation :

[tex]slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\ [/tex]

[tex]slope = \frac{ - 23 + 3}{ - 18 + 3 } \\ [/tex]

[tex]slope = \frac{ - 20}{ - 15} \\ [/tex]

Negatives simplified :

[tex]slope = \frac{20}{15} \\ [/tex]

The face and denominator are reduced to five :

[tex]slope = \frac{4}{3} \\ [/tex]

_________________________________

And we're done.

Thanks for watching buddy good luck.
