Explanation:

Step 1: Define

y = 1.2345x - 0.6789

y = 0.570

Step 2: Solve for x

Substitute in y:                                                                                                0.570 = 1.2345x - 0.6789[Addition Property of Equality] Add 0.6789 on both sides:                        1.2489 = 1.2345x[Division Property of Equality] Divide 1.2345 on both sides:                      1.01166 = xRewrite/Rearrange:                                                                                        x = 1.01166

Idon’t know sorry i don’t know the answer i’m s sorry

(no3)⁻n has oxidation number x,o has oxidation number -2.(x*1 -2*3) charge of the nitrate ion, and we know that charge of the nitrate ion =-1.so,(x*1 -2*3) =-1x-6=-1x=+5answer a. +5.
