Wires go between Boston, Chicago, and Seattle. Those cities are at voltages
xB, xC, xS.
With unit resistances between cities, the three currents are in y:
y=Ax is ⎡⎣⎢yBCyCSyBS⎤⎦⎥=⎡⎣⎢101−1100−1−1⎤⎦⎥⎡ ⎣⎢xBxCxS⎤⎦⎥.
(a) Find the total currents
ATy
out of the three cities. (b) Verify that
(Ax)Ty
agrees with
xT(ATy)
six terms in both.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
