Determine the truth value of each statement in each item. The domain of discourse is the set of real numbers. Justify your answers. 1.For some x, for some y, x2 < y + 1
2.For every x, for every y, x2 + y2 = 9
3.For some x, for some y, x2 + y2 = 9
4.For some x, for every y, x2 + y2 = ≥0
5.For every x, for some y, if x < y, then x2 < y2

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points

discount price = (original price)(1 – 0.15)

is the right answer   on edge
