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 <:

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
