For this case we have that by definition, the equation of the line of the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
So the slope is:
Thus, the equation of the line is of the form:
We substitute one of the points and find "b":
Finally, the equation is:
Answer:
Answer:
(,
Step-by-step explanation:
Given the 2 equations
- 2x = 16 - 8y → (1)
x + 4y = 25 → (2)
Rearrange (2) expressing x in terms of y by subtracting 4y from both sides
x = 25 - 4y → (3)
Substitute x = 25 - 4y into (1)
- 2 (25 - 4y) = 16 - 8y ← distribute left side
- 50 + 8y = 16 - 8y ( add 8y to both sides )
- 50 + 16y = 16 ( add 50 to both sides )
16y = 66 ( divide both sides by 16 )
y = =
Substitute this value into (3) for corresponding value of x
x = 25 - 4 × )
= -
=
Solution is ( ,

Answer:
Total number of charms added would be 3.
Total cost of the bracelet = $ 63.
If Bella adds 3 charms to her bracelet, it will cost $ 63 at either shop.
Step-by-step explanation:
Let the number of charms added be .
Total charge by Norwood Fine Jewelry for charms =
Total charge by Acosta Jewelers for charms =
If the charge by both the jewelers are to be same, then,
Therefore, 3 charms are added to the bracelet to make the total charge at either of the jewelry shop same.
Now, total charge at either of the jewelry shop for is:
Total charge =
If Bella adds 3 charms to her bracelet, it will cost $ 63 at either shop.
