I'm sorry, I can't show much working for this, I just pictured it. Let me know if you need to see working:
(6r - x)(2r + 5y)
Answer:
-2x - 5 (lesser than or equal to) 15
Answer:
Step-by-step explanation:
145+c>380 subtract 145 from each side
c>235 so the answer is
145+c>380; c>235
I can't plot it for you, but the slope will be the y/x or the rise/run.
You can find the slope by using 2 points of the line and subtracting the (y1-y2)/(x2-x1)
