Write a real-world situation for 7.50y + 9

Talja [164]

Answer:

Step-by-step explanation:

This equation is written in slope-intercept form, meaning that the value next to the variable (7.50) is the rate (slope) and the other number is the y-intercept (9).

So you can say that you mowed the lawn at $9 up front and 7.50 every hour (or half-hour whatever you want).

Rewrite this formula to convert Fahrenheit to Celsius (linear equations and inequalities)

Luba_88 [7]

Answer:

The formula used to convert Fahrenheit in to Celsius is:

$C = ( F - 32) \times (\frac{5}{9})$

Step-by-step explanation:

Here, the given expression is :

$F=(\frac{9}{5}) c + 32$

The above expression converts Celsius in to Fahrenheit.

Now we need an expression to convert Fahrenheit in to Celsius.

Simplifying the above for the value of C, we get:

$F=(\frac{9}{5}) c + 32\\\implies F - 32 =(\frac{9}{5}) c \\\implies ( F - 32) \times (\frac{5}{9}) = c\\\implies C = ( F - 32) \times (\frac{5}{9})$

Hence, the formula used to convert Fahrenheit in to Celsius is:

$C = ( F - 32) \times (\frac{5}{9})$
