A charm bracelet costs $65, plus $25 for each charm. The equation -25x+y=65 represents the cost y (in dollars) of the bracelet,
where x is the number of charms.
a. Graph the equation.
b. How much does a bracelet with three charms cost?

1 answer:
Answer:
a. see attached
b. $140
Step-by-step explanation:
<h3>a.</h3>The graph starts at y=65 when x=0 and increases by 25 for each increase of 1 in x. The attachment shows a graph of the equation.
__
<h3>b.</h3>Use x=3 in the equation.
-25x +y = 65
y = 65 +25x = 65 +25(3) = 140
A bracelet with 3 charms costs $140.

Answer:
Step-by-step explanation:
The axes x and y are calibrated in 0.25
If the circle is carefully considered, the radius r of the circle is:
r = -1.25 - (-2)
r = 0.75 units
The equation of a circle is given by:
The center of the circle (a, b) = (-2, -2)
Substituting (a, b) = (-2, -2) and r = 0.75 into the given equation:
