Answer:
4.5
Step-by-step explanation:
→ Set up the direct proportion equation
z = kx
→ Substitute in the values
12 = 3k
→ Divide both sides by 3 to isolate k
4 = k
→ Substitute the value of k back into the original direct proportion equation
z = 4x
→ Substitute the value of z in
18 = 4x
→ Divide both sides by 4 to isolate x
4.5 = x
The absolute value of -5 would be 5
Hope this helps, and have a nice day
Yes, because you need to remember and/or list out your square roots no matter what.
Answer:
-x² - 4x + 6
Step-by-step explanation:
(-2x² - 3x + 4) - (-x² + x - 2) =
= -2x² - 3x + 4 + x² - x + 2
= -x² - 4x + 6
