Which of the following expressions is equivalent to -5.4 - (2.1 + 1.8)? A. -5.4 - (2.1 - 1.8)
B. -5.4 - (-2.1 - 1.8)
C. -5.4 + (-2.1 + 1.8)
D. -5.4 + -(2.1 + 1.8)

Step-by-step explanation:

i would also choose d for my answer too

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.
