To find f(3), plug x = 3 in f(x),
∴ f(3) = 3(3)+1 = 9+1 = 10
Therefore, the ordered pair is (3,10)
For second one,
plug x = 10 in f⁻¹(x),
f⁻¹(10) = 10-1/3 = 9/3 = 3
Therefore, the ordered pair is (10,3)
Answer:
there would have been 12 crackers on the plate at the start
Step-by-step explanation:
So 1/3 +1/4 = 7/12
Therefore 5/12 left on the plate …ie 5.
So total to start with
5/5×12=12
Ans 12
The equation of the line is y =
x + 9
Step-by-step explanation:
The equation of a line in slope-intercept form is y = m x + b, where
- m is the slope of the line
- b is the y-intercept ⇒ the value of y when x = 0
∵ The line has a slope 
∴ m = 
∵ The y-intercept is 9
∴ b = 9
- Substitute the values of m and b in the form of the equation below
∵ y = m x + b
∴ y =
x + 9
The equation of the line is y =
x + 9
