Answer:
24 cent
Step-by-step explanation:
If 13 inches of wire cost 39 cent.
We have to calculate how much 1 inch of wire would cost first, before determining the cost of 8 inches of wire.
If 13 inches of wire costs 39cents, Then 1 inch of wire would cost 3 cent.
That is 39/13, which gives 3.
If 1 inch of wire cost 3 cents. Two inches of wire would cost 6 cents we 3 inches of wire costs 9 cents.
To get the cost of 8 inches of wire, we therefore multiply 8 by 3, which gives 24.
8 inches of wire costs 24 cents.
Answer:
solid...(-3,0)(-4,-1)...shaded below the line
slope = (-1-0) / (-4-(-3) = -1/(-4 + 3) = -1/-1 = 1
y = mx + b
-1 = 1(-4) + b
-1 = -4 + b
-1 + 4 = b
3 = b
this line is : y < = x + 3 <== (thats less then or equal)
====================
solid...(1,1)(2,-1)...shaded below the line
slope = (-1-1) / (2-1) = -2/1 = -2
y = mx + b
1 = -2(1) + b
1 = -2 + b
1 + 2 = b
3 = b
Step-by-step explanation:
True multiply both sides by 15
