Answer:

1. –X + Y = -22X – Y = 6

2. X + Y = 5-2X + Y = -4

Step-by-step explanation:

y-intercept = (0, 4)

x-intercept = (3/4, 0)

1 - Find the slope

[tex]slope = m = \frac{rise}{run} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac {-11-10}{5-(-2)} = \frac {-21}{7} = -3[/tex]

2 - Plug the slope into y = mx + b and substitute a point into x and y to find the y-intercept, b, by isolating it.

y = mx + b

y = -3x + b

10 = (-3)(-2) + b

10 = 6 + b

-6   -6

4 = b

y-intercept = (0, 4)

3 - Rewrite the completed formula

y = -3x + 4

4 - Substitute 0 in for y to find the x-intercept

0 = -3x + 4

-4          - 4

-4 = -3x

-4/-3 = -3x/-3

 4/3 = x

x-intercept = (4/3, 0)

An equation that will give you the costs at different times is y = [tex]1.048^{t}[/tex].

The price of the dinner in 60 years will be $425.04.

An exponential function is usually in the form: [tex]ab^{x}[/tex].

Where:

Rate of increase = (cost of the meal now / cost of the meal 60 years ago)^(1 / number of years)

(25.25 / $1.50) ^(1/60) = 4.8%

y = [tex]1.048^{t}[/tex].

25.25 x 1.048^60 = $425.04

Answer:

x=20

Step-by-step explanation:

so 5/4 is 1.25

so 25/x=1.25

so to find x we do 25/1.25

when we do that we get 20 so then to check if it's right we divide 25/20 and we get 1.25 so it's right

Step-by-step explanation:

Given that:

Equation of regression line : y^ = 60.7 + 0.139x

x = payroll (in millions of dollars) and y = number of wins for Major League Baseball teams in 2016.

From the general regression equation:

y = mx + c

Where m = slope of regression line.

The slope (m) of the equation given is 0.139

The slope could be interpreted as ; for every per unit change in y (every win a major league baseball team has in 2016), the payroll in million dollar increases by a product of 0.139

The slope of a regression line is the average rate of change of the line.

The interpretation of the slope is: the rate of wins per payroll is 13.9%

From the question, we have:

[tex]\mathbf{\bar y= 60.7 + 0.139x}[/tex]

The equation of a linear regression is:

[tex]\mathbf{\bar y= c + mx}[/tex]

Where m represents the slope

So, by comparison:

[tex]\mathbf{m = 0.139}[/tex]

[tex]\mathbf{m = 13.9\%}[/tex]

This means that, the rate of wins per payroll is 13.9%

Bc x turn into 1/10

Yes, the equation y = x/10 do represent a proportional relationship.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Given an equation, y = x/10

This equation is representing a proportional relationship because in the equation there are two equal ratios and according to definition of proportion, the equation is proportional.

Hence, the equation y = x/10 do represent a proportional relationship.
