Answer:
k = -8
Step-by-step explanation:
The location of P is ...
P = (2A+B)/3 = (2·2+5, 2·1-8)/3 = (3, -2)
Putting this point into the equation for the line, we have ...
2(3) -(-2) +k = 0
8 +k = 0
k = -8

Answer:
(x) =
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x = (x) , then
(x) =
Here is the equation:
Since 4 is next to the parentheses, you have to multiply everything in the parentheses by 4.
First multiply 3x by 4:
Now multiply 2 by 4:
Now add them together:
Your answer is <u>12x + 8</u>
