Answer:
v=3d/7 - 5/7
Step-by-step explanation:
3d=7v+5
-5 -5
<u>3d</u>-<u>5</u>=<u>7v</u>
7 7 7
3d/7 - 5/7=v
v=3d/7 - 5/7
Answer:
28
Step-by-step explanation:
I guessed it right on hegarty maths and this was the answer
Let's start with deleting +3d and -3d (because they have opposite signs)
8d-8 = 3d
Move unknown term (3d) to the left of equal with changed sign and known term (-8) to the right of equal with chenged sign.
8d-3d = 8
5d = 8
Divide both for 5
5d/5 = 8/5
d = 8/5
To change it into slope intercept (y=mx+b) you just replace the inequality with an equality and isolate y
x<=2:
x=2=y-> y=2 or y=2+0x
2x-3y>=4:
2x-3y=4
2x-4=3y
(2/3)x-(4/3))=y
y=(2/3)x-(4/3)
x+y>0:
x+y=0
y=-x or y=-x+0
