Hello!

Solve for y by isolating the variable.

Solve for y[tex]-20x + 10y = 30[/tex][tex]10y = 30 + 20x[/tex][tex]y = \frac{30 + 20x}{10}[/tex][tex]y = \frac{(10)(3 + 2x)}{10}[/tex][tex]y = 3 + 2x[/tex][tex]y = 2x + 3[/tex]

The solution is y = 2x + 3.

To Calculate :-

Value of y.

Solution :-

-20x + 10y = 30

Transposing (-20x) to R.H.S. sign would be changed to positive.

10y = 30 + 20x

y = 30 + 20x / 10

y = 10 (3 + 2x) / 10

Cancelling 10,

y = 3 + 2x / 1

y = 2x + 3

If the tan V=4/3, what is the value of sec V

Answers

The value of sec(V) is 5/3

How to solve the trigonometry expression?

The tangent is given as:

tan(V) = 4/3

To solve for sec(V), we use the following identity

sec^2(V) = tan^2(V) + 1

So, we have:

sec^2(V) = (4/3)^2 + 1

This gives

sec^2(V) = 16/9 + 1

Evaluate the sum

sec^2(V) = 25/9

Take the square root

sec(V) = 5/3

Hence, the value of sec(V) is 5/3

Assume the following 5 scores represent a sample: 2, 3, 5, 5, 6. Transform these scores into z-scores. Show all steps

Answers

The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

How to transform the scores?

The sample scores are given as:

2, 3, 5, 5, 6.

Calculate the mean and the standard deviation using a statistical calculator.

From the statistical calculator, we have:

[tex]\bar x = 4.2[/tex] --- mean

[tex]\sigma_x = 1.64[/tex] --- standard deviation

The z-score is then calculated using

[tex]z= \frac{x - \bar x}{\sigma}[/tex]

Where:

x = 2, 3, 5, 5, 6.

So, we have:

[tex]z_1= \frac{2 - 4.2}{1.64} = -1.34[/tex]

[tex]z_2= \frac{3 - 4.2}{1.64} = -0.73[/tex]

[tex]z_3= \frac{5 - 4.2}{1.64} = 0.48[/tex]

[tex]z_4= \frac{5 - 4.2}{1.64} = 0.48[/tex]

[tex]z_5= \frac{6 - 4.2}{1.64} = 1.10[/tex]

Answers

Using equation, He bought 3 boxes of ballpoint pens and 15  boxes of felt-tip pens

How to find the boxes of each type of pen using equation?

let

x = number of boxes of ballpoint pens

y = number of boxes of felt-tip pens

Therefore, the situation will form an equation.

x = 5y

Hence,

4.33x + 3.42y = 75.21,

4.33(5y) +  3.42y = 75.21

21.65y + 3.42y = 75.21

25.07y = 75.21

y = 75.21 / 25.07

y = 3

x = 5(3) = 15

Hence, he bought 3 boxes of ballpoint pens and 15  boxes of felt-tip pens

Line AB contains points A (8,-4) and B (1, -5). The slope of line AB is

Answers

Let, the points be A (8, −4) and B (1, −5). The slope of line AB exists 1/7.

How to estimate the slope of line AB?

Utilize the slope formula to estimate the slope of a line provided the coordinates of two points on the line.

The slope formula exists [tex]$m = (y_{2} -y_{1})/(x_{2} - x_{1} )[/tex], or the difference in the y values over the difference in the x values. The coordinates of the first point symbolize [tex]$x_{1}[/tex]and [tex]$y_{1}[/tex]. The coordinates of the second points exist [tex]$x_{2} , y_{2} .[/tex]

The slope of the line exists the ratio of the rise to the run, or rise separated by the run.

[tex]$m = (y_{2} -y_{1})/(x_{2} - x_{1} )[/tex]

The Line, AB contains points A (8, −4) and B (1, −5).

Substitute the value of points in the equation then we get

[tex]$m = (y_{2} -y_{1})/(x_{2} - x_{1} )[/tex]

m = (-5-(-4))/(1 - 8)

Simplifying the above equation, we get

m = (-5+4)/(1 - 8)

m = (-1)/(-7)

m = 1/7
