Kaitlyn solved the equation for x using the following calculations. -5.4 +x =12.2 -5.4 -5.4= x=6.8: A:She should have added 5.4 to each side B:She should have added the inverse of 5.4 to each side C: She made a computational error when she subtracted 5.4 from 12.2 D:She should have added 12.2 to each side.

its 100% not B,D,C its has to be A

Step-by-step explanation:

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
