One way is to make it into slope intercept form which is
y=mx+b
m=slope
b=y intercept or where the line will go though the y axis
treat the equal to or greater than sign as equals for now
5x-y=5
subtract y from both sides
5x=5+y
subtract 5
5x-5=y
put the sign back in
5x-5 ≥ y
reverse
y ≤ 5x-5
one way is to subsitute values and get values out so
if x=1 then
y≤5(1)-5
y≤0
(x,y)
(1,0)
(2,5)
(3,10)
(4,15)
(0,-5)
plot the points
then the ≤ sign
since ther is an underline, that means that the points are included so draw a solid line through the points
then figure out which side to shade on
the easy way is, is the point (0,0) a solution?
subsitute
0 ≤ 5(0)-5
0 ≤ -5
false so we shade the section that does not include the point (0,0) in it
the graph would look like this attachment
1. 5 brothers
2. 63 students
3. 6 fewer lions
4. 40 children
5. 35 trees
6. 18 times
Answer:
y=2x+1
Step-by-step explanation:
change -2x to 2x
answer: $215.10
the TV's original price is $239, but with 10% off, it is now 90% of the original price. therefore we have to find 90% of 239:
0.90*239=215.10
Answer:
y>= -2
Step-by-step explanation:
-5y=< 2+8
-5=< 10
y>= -2
