The answer would be 12.571428571 units or 12.57units.
Here’s the answer because I can’t do the arrow thing on phone
Answer:
i got x=-135
Step-by-step explanation:
lets solve!
first remove the parentheses= x-1.2x=27
second you collect like terms= -0.2x=27
last divide both sides by -.02 = x=-135
hope this helps you!! :)
We can usually get a couple of facts for these that let us rule out answers without working out all the details.
The green and red areas are below a CUP parabola, opening up. CUP stands for concave up positive, and tells us there's a positive coefficient on x². Unfortunately all the choices have a positive 1 coefficient, no help here.
Since the areas are below they're going to be y ≤ x² + other stuff. That rules out B and C.
The red and blue parts are below the line, and the line has a positive slope. So that's y ≤ mx + b where m>0 is the positive slope. That rules out D with the negative slope.
Answer: A
