The unit price per padlock would be $4.40
Work: $17.60 (17.60)÷4= 4.4 ($4.40)
Answer:
option on first row on the right
Step-by-step explanation:
Since the inequality contains an equal sign, the boundary line must be included in the graph (it should appear as solid)then you need the points y that are less (below) those on the boundary line. So you should highlight the half plane below the boundary line.
Answer:
A) y - 2 = 3(x+4)
Step-by-step explanation:
Given that the equation is a line with slope =m=3 and
a point on it (x1,y1) = (-4,2)
Any line having slope m and passing through (x1,y1) has equation in point slope form as
y-y1 = m(x-x1)
We are given here x1 =-4, y1 =2 and m =3
y-y1 = y-2 and x-x1 = x-(-4) = x+4
So equation is y-2 = 3(x+4)
Verify:
The line is y = 3x+12+2 = 3x+14
Hence slope =3 is verified
Substitute the point x =-4 and y =2
2 =3(-4)+14 = 2 is true
Thus verified
