I really dont get it halp ;-;

II

Step-by-step explanation:

This would be easier to explain to you on a graph, but I shall do the best I can in text format.

You know what a complex plane looks like, right? Just like a number line but with a vertical number line added on at the point (0). This makes four quadrants, you know the drill.

So each quadrant holds all values from on of the four positive/negative combinations, (1, 1i), (1, -1i), (-1, -1i), and (-1, 1i), in that order.

So this means that all the pairs with both positive values are in quadrant I, all the pairs with a positive rational number but a negative irrational number are in II, etc.

If you have a graph, you can simply count along the number line to find the answer, so in this case, starting as always at (0, 0), move 6 units to the right and then eight units down, where you end up in the lower righthand quadrant, which is II.

Oof I know that was worded badly but I hope it's not totally useless to you <3

You're doing great with the test, Gem, I'm sure you'll do just fine <:

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

the expected value of the random variable : 0, 1 and 2
