Answer:
Yes
Step-by-step explanation:
using distributive properties,
(3x+1)(4x-5) = 3x(4x-5) + 1(4x-5)
=> 12x^2 - 15x +4x - 5
=> 12x^2 - 11x - 5
The equation of the tangent line will be y = -3x + 8.
<h3>What is a linear equation?</h3>
A straight line on the coordinate plane is represented by a linear equation.
A linear equation always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
Given curve
f(x) = x² - 7x + 12
The slope of the tangent equation = the first derivative of a function at that point (2,2).
So,
f'(x) = m = 2x - 7
At (2,2) ⇒ m = -3
Now let's say the equation of tangent
y = mx + c
2 = (-3)2 + c
c = 8
So,
Equation of tangent line on the curve f(x) = x² - 7x + 12 will be y = -3x + 8.

If the name of the function is pay, wtih nickname p, and the variable is the numbers of hours of training, then the expression for 20 hours of payment is pay (20) or p(20).
In this case pay or p is the dependent variable and hours is the independent variable.
