Answers

Answer:

y = 42 + 7x

Step-by-step explanation:

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that the temperature at sunrise is 42°F.

Each​ hour, the temperature rises 7°F.

We need to find the equation that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

y=42+7x is the equation  that models the temperature​ y, in degrees​ Fahrenheit, after x hours.

We have to draw the graph by taking few points.

x     0    1      2       3

y    42   49   56    63

Answers

Answer

x>21.2

Step-by-step explanation:

7.55x+100>160:

subtract 100 on both sides to get:

7.55x>60:

divide 7.55 on both sides:

x>21.2 is your answer  

 

Answer:

7.50h + 100 > 160

Step-by-step explanation:

7.50 is the hourly wage

h = hours he worked

add 100 once because it's his tips for the amount of time her worked

since he worked more than 160, you'll use the greater sign

then solve for h

h = 8 hours
