For this case we have the following situation:

The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.

So we have to define variables:

x: number of months

y: total cost

The mathematical expression that models the problem is:

y = 3x + 25

The slope of the function, f(x) can be determined by choosing two sets of ordered pairs from the table and substituting their values into the slope formula.

Let (x1, y1) = (0, -1)
(x2, y2) = (1, 7)

Plug these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

m = [7 - (-1)] / [1 - 0]
m = (7 + 1) / 1
m = 8/1 or 8.

Therefore, the slope of f(x), m = 8.

The y-intercept of the function, f(x) is given by (0, -1), as it is the point on the graph where it crosses the y-axis. It is also the value of y when x = 0.

The equation of the linear function, f(x) is:
f(x) = 8x - 1.

Given the slope-intercept form, y = mx + b, where m represents the slope of the line, and b represents the y-intercept:

The function, g(x) = 3x - 2 has a slope of 3, and y-intercept of -2.

Comparing the slope and y-intercept of the two functions, f(x) and g(x):

The slope of f(x), m = 8 is greater and steeper than the slope of g(x), m = 3. The y-intercept of f(x), b = -1 is greater than the y-intercept of g(x), b = -2.

Attached is a screenshot of the graph of both lines, including their y-intercepts. The blue line is g(x) = 3x - 2, and the red line is f(x) = 8x - 1.

Katrina wrote the standard form of a linear equation as 4x-2/3y=8. Sophia told her that the equation was not yet in standard for
Angelina_Jolie [31]

Answer:

  multiply by 3 and divide by 2 to get 6x -y = 12.

Step-by-step explanation:

A standard form equation has mutually prime integers for coefficients, and the leading one is positive. We can get that here by multiplying by 3 (to eliminate the denominator) and dividing by 2 (to remove that common factor). The result is ...

  4(3/2)x -(2/3)(3/2)y = 8(3/2)

  6x -y = 12
