Answer:
Equation: y=7x
y=-28
Step-by-step explanation:
y=kx
y=98
x=14
98=14k
98/14=7
k=7
Equation: y=7x
x=-4
y=7•-4
y=-28
Answer:
The height of the equilateral triangle is 
Step-by-step explanation:
we know that
An equilateral triangle has three congruent sides, and three congruent angles that each measure 60 degrees
To find out the height of an equilateral triangle, apply the Pythagoras Theorem in the right triangle ABD
Remember that the height of an equilateral triangle bisects the base.
see the attached figure to better understand the problem

substitute the given values

Answer: P(x) = 0.50x - 5</h3>
==========================================
Explanation:
x = number of glasses sold
She charges $0.50 per glass, so her revenue is
R(x) = 0.50x
which is the amount of money she brings in
--------
Her cost function is
C(x) = 5
assuming she only spends that $5.00 on the supplies mentioned.
--------
The profit P(x) is the difference of revenue and cost
Profit = Revenue - Cost
P(x) = R(x) - C(x)
P(x) = 0.50x - 5
