C) 10
Step-by-step explanation:
hope it helps youuuuuu
Actually Welcome to the Concept of the Functions.
so after plotting the graphs, we get as,
==> m = 2.5
==> b = 0
==> y = mx+c
a straight line
Option D should be your answer.
No combo of any of those angles add up to exactly 180 to suggest that they are parallel lines.
For a problem like this, you'll want to break it down ...
Total cost = $19.60.
Cost of beads = $12.80.
Cost of pendant = ?
We know that there are 4 necklaces. Each necklace has one pendant, so we have 5 pendants total. Therefore, your solution should look something like this ...
Total cost = Cost of beads - cost of pendant
$19.60 = 12.80 - 4x <- x is the variable representing the price for a single pendant.
6.80 = 4x <- Subtract 12.80 from both sides.
x = 1.70 <- Divide both sides by 4, and find your final answer.
x = 1.70; therfore, each pendant costs $1.70.
For the part b of the question please find the attached image.
