10x-3Y=-150 how do you solve and graph?
1 answer:
Add 3y to both sides
10x = -150 +3y
subtract -150 from both both sides
10x + 150 = 3y
then divide both sides by 3 (and going to switch the two sides cuz i prefer it that way)
y = (10/3)x + 50
so for graphing you take the y intercept
which is 50 and put a point there
slope (10/3) is rise/over run
so going down and to the left from your y intercept (cuz the slope is positive) count 10 then go over 3
put a point
do it again
then for the other way go up 10 and over 3
that’s graphing
i’ll graph it too but it’ll be sloppy so i figured i’d explain it too

Answer:
Y = 3 And x = 3
Step-by-step explanation:
Because this is a 45 to 45 degree triangle, the 3 * (square root of 2 )/2 is y as well. Because this is a 45-45 triangle, x should be y (Square root of 2). Therefore, replacing y with 3 * (square root of 2 )/2 and multiply the square root of 2, the answer for x is 3. If I got something wrong please tell me, thanks.
