Answer and Explanation:
You got the first one right!
2. You do the same as you did for the first one: to combine the exponents, you multiple 2 by 9 = 18, and now 18 is your new exponent.
, which is the answer
3. Here, you can split up the inside so that you have:
, which is the answer
Hope this helps! Please give me brainliest if possible.
Hint:
Ax+By+C= D
is parallel to
Ax+By+C= E
So in this case,
2x−9y+4z=5
is parallel to
2x−9y+4z=k
for any real number k
Answer:
a- 1/4 x 2/1

Answer:
-2x + 4
