Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 35x + 25
g(x) = 22x + 18
f(4) is <em>x</em> = 4 for function f(x)
g(10) is <em>x</em> = 10 for function g(x)
<u>Step 2: Find Function Values</u>
<em>f(4)</em>
- Substitute in <em>x</em> [Function f(x)]: f(4) = 35(4) + 25
- Multiply: f(4) = 140 + 25
- Add: 165
<em>g(10)</em>
- Substitute in <em>x</em> [Function g(x)]: g(10) = 22(10) + 18
- Multiply: g(10) = 220 + 18
- Add: g(10) = 238
<u>Step 3: Evaluate</u>
- Substitute in function values: 5(165) + 2(238)
- Multiply: 825 + 476
- Add: 1301
Answer:
The rate is 
Step-by-step explanation:
we know that
The formula to calculate the rate or slope between two points is equal to 
Let
x----> the time in minutes
y-----> the temperature in Celsius degrees
we have
Substitute the values
Answer: 4.5 days or 4 1/2 days
Step-by-step explanation: We can use cross product property, to solve this. Workers to Days remember that
$18.11 because 20.75/x=100/15
<span>(120.75/x)*x=(100/15)*x - </span>we multiply both sides of the equation by x
<span>120.75=6.6666666666667*x - </span>we divide both sides of the equation by (6.6666666666667) to get x
<span>120.75/6.6666666666667=x </span>
<span>18.1125=x </span>
<span>x=18.1125</span>
