Let's do this step by step:
Subtract both sides by 7
-2|x-4|= -10
Divide each side by -2
|x-4|= 5
Now since this is an absolute value equation, you will have two answers. This means you make the equation both positive and negative.
X-4= 5and -(x-4)= 5
Solve for x for both
X-4= 5: add four on both sides
X= 9
-x+ 4= 5: subtract 4 and divide by -1
X= -1
So your answer is: X= -1 , 9
Answer: x^3 + x^2 - 17x + 12
Step-by-step explanation:
(x+4)(x^2-5x+3)
x^3 - 5x^2 + <u>3x</u> + 4x^2 <u>- 20x</u> + 12
underlined and bolded can be combined
That leaves you with x^3 + x^2 - 17x + 12
Answer:
Sorry man but I can't see the question : (
Step-by-step explanation:
For the fifth term, n = 5.
Just replace n with 5 in the expression.
Then evaluate the expression.

Answer:
x = 18/5
Step-by-step explanation:
-5/6 x=-3
Multiply each side by -6/5
-6/5 *-5/6 x=-3*-6/5
x = 18/5
