Answer:

67.5 degrees

Step-by-step explanation:

The angles at the center of the figure = 360 degrees

Therefore, 3x + x + 90 degrees = 360 degrees

simplifying:

4x + 90 degrees = 360 degrees

4x = 360 - 90

4x = 270 degrees

x = 270÷ 4

x = 67.5 degrees

The equation and table shows were two boys pay for gym fees compare the rate of change and initial value for each function
Olegator [25]

The equation is an illustration of a linear function

The rate of change is 10 and the initial value is 25

<h3>How to determine the rate of change and the initial value</h3>

The equation is given as:

C = 25 + 10m

A linear equation is represented as:

y = b +  mx

Where:

  • b represents the initial value
  • m represents the rate

By comparison:

b = 25

m = 10

Hence, the rate of change is 10 and the initial value is 25
