The value of f(r - 2) is 6r - 5
<h3>What is a function?</h3>
Function can be defined as an expression, rule, or law that defines a relationship between one variable known as the independent variable and another called the dependent variable.
From the information given ,we have;
f(x)= 6x+7, with f ( r - 2)
From here, we have that x = r -2
Now, let's substitute x as r - 2 in the function given;
f(x) = 6x + 7
f(r - 2) = 6 ( r - 2) + 7
Expand the bracket
f(r - 2) = 6r - 12 + 7
collect like terms
f(r - 2) = 6r - 5
Thus, the value of f(r - 2) is 6r - 5

Answer:
d = 70t
Step-by-step explanation:
The units of speed tell you how to write the equation.
speed = miles/hour
Multiplying by hours gives ...
speed · hours = miles
Using the required variables and the given speed, you have ...
70t = d . . . . . time in hours, distance in miles
