Answer:
Its good and yours? ill try to answer ur question i might not know lol
Step-by-step explanation:
Answer:
two points in the xy plane have cartesian coordinate (2,-4)and (-3,3) where the units are in m determine.
a)the distance between these point and
b) their polar coordinates
One pack of strings is $14. This is because 72-16=56. I subtracted the 16 because it is how much the book cost, so it does not have anything to do with the amount one pack of strings cost. Then, I divided 56 by 4 which equals 14. I divided 56 by 4 because the question is how much one pack is, and Noah and Kate bought a total of 4 packs. This proves that one pack of strings costs $14.
Hope this helps you!
well for a line, to get its slope all we need is two points, so let's use (-6, 5) and (0, 1), and get the equation of it.

now, where's the y-intercept of that line? well, to get the y-intercept, we set x = 0 and solve for "y"....hmmmm wait a second, notice (0, 1), x = 0, y = 1, that's the y-intercept already.
