Since our line is perpendicular to this line, the slope of
our line is the negative reciprocal of 1/4, which is -4/1.
Remember, negative reciprocal is just a fancy way
of saying flip the fraction and change the sign.
So the slope of our line is -4/1 and we use this slope along
with our given point to write the equation of our line.
Start with the point-slope formula.
Y - y1 = m(x - x1).
~Substitute
Y - -2 = -4/1(x - 5).
Minus a negative is plus a positive.
Y + 2 = -4/1x + 20.
Subtract 2 from both sides.
Y = -4/1x + 18
So, our answer is C.

Answer:
Nina would have total expenses and sales $156 after selling 4 necklaces.
Step-by-step explanation:
Let <em>x</em> represent the amount of necklaces made and sold.
The initial cost was $140 and it costs $4 to produce one necklace. Hence, the total cost after producing <em>x</em> necklaces can be represented as:

Each necklace sells for $39. Hence, the total profit after selling <em>x</em> necklaces can be represented as:

To break even, the total cost and profit must be equivalent. Hence:

Solve for <em>x: </em>
<em />
<em />
<em />
Hence, the break even, Nina would need to sell four necklaces.
And the total expenses/profit would be:

In conclusion, Nina would have total expenses and sales $156 after selling 4 necklaces.
Answer:
v = 2034.72 mm³
Step-by-step explanation:
radius = 18mm
height = 6mm
pi = 3.14
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
