Plug in -3n as n into the functon K(n)=4n+5
so you get
K(-3n)=4(-3n)+5
K(-3n)=-12n+5
Answer:
0.5
Step-by-step explanation:
The rate of change is the same as the slope. The equation y=0.5x+9 is written in slope intercept form, so 0.5 is the slope.
Answer:
n=15
Step-by-step explanation:
subtract 8 from both sides to get 3n=45
divide both sides by 3 to solve for n to get n=15
The slope is 4 and the y-intercept is 
Step-by-step explanation:
The general form of a linear equation is Ax + By + C = 0, where
- A is the coefficient of x
- B is the coefficient of y
- C is the numerical term
- A, B, and C are integers
- The slope of the line =

- The y-intercept =

∵ The linear equation is 0 = 2 - 3y + 12x
- Switch the two sides and arrange the terms as the general
form above
∴ 12x - 3y + 3 = 0
∴ A = 12
∴ B = -3
∴ C = 2
∵ The slope of the line = 
- Substitute A by 12 and B by -3
∴ The slope of the line = 
∴ The slope of the line = 4
∵ The y-intercept = 
- Substitute C by 2 and B by -3
∴ The y-intercept = 
∴ The y-intercept = 
The slope is 4 and the y-intercept is

Answer:
9
Step-by-step explanation:
because 9 is in front of the variable y
whenever there is a number before a variable then that number is a coefficient
For example:
3x+2x+5x=y
3,2,5 are all coefficients of x
