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

The battery on McKenzies old computer can last 4(1/5) hours. She bought a new computer that has a battery that can last 40% long
Solnce55 [7]

Answer:

5\frac{22}{25}\ hours

Step-by-step explanation:

we know that

4\frac{1}{5}\ hours=\frac{4*5+1}{5}=\frac{21}{5}\ hours

100\%+40\%=140\%=\frac{140}{100}

Let

x ------> new battery life

The equation that represent this situation is

x=\frac{140}{100} (\frac{21}{5})=\frac{2,940}{500}\ hours

convert to mixed number

\frac{2,940}{500}=\frac{2,500}{500}+\frac{440}{500}=5\frac{22}{25}\ hours
