i say A
Step-by-step explanation:
Answer:
x=-2/k
Step-by-step explanation:
To solve you need to make x on one side while the other variables or numbers on the other.
First, you need to move the 9 to the other side by subtracting 9 from both sides: kx+9-9=7-9
Simplify: kx=-2
Now you need to divide by k into both sides in order to eliminate the k on kx:
x=-2/k
Answer: x=-2/k
Hope this helps!
Answer:
Just factorize the given plynomials.
Step-by-step explanation:
like in first example 7x+49
7(x+7)
Basically you’re multiplying them both
(x^3 + 2x - 1)(x^4 - x^3 + 3)
so you need to make sure you multiply each one, if you do it right, you should end up with
x^7 - x^6 + 3x^3 + 2x^5 - 2x^4 + 6x -x^4 +x^3 -3
simplify by adding like terms
x^7 - x^6 + 2x^5 - 3x^4 + 4x^3 + 6x - 3
your answer would be the third option
Answer:
-23
Explanation:
To find the value of the expression when x = -3, we simply put in -3 wherever we find x - doing this gives
which is our answer!
