Answer:
p=(-0.0125n) + 42.5
Step-by-step explanation:
Let p= price
n = number of shirts
m = slope of the line (note, the more shirts, the lower the price, so we know it's going to be negative)
b = y intercept
There are two points which are (1000, $30) and (3000, $5)
Our slope m = (p1-p2)/(n1-n2)
Filling in from our points m = (30-5)/(1000-3000)
m = 25/-2000
m = -0.0125
Since we have determined our slope, we can now find our equation
p-p1=m(n-n1)
p-30=(-0.0125)(n-1000)
p-30= (-0.0125n) + 12.5
p=(-0.0125n) + 42.5
Then, we can double check with the other point there:
p=(-0.0125n) + 42.5
5? (-0.0125x 3000) + 42.5
5= 5
Therefore,linear equation in the form p(n) is
p=(-0.0125n) + 42.5

Answer: 8</h3>
===========================================================
Explanation:
All direct variation equations are of the form y = kx, for some constant k.
We know that y = -8 and x = 4 pair up together. Let's use these two values to find k
y = kx
-8 = k*4
-8/4 = k
-2 = k
k = -2
Therefore, we go from y = kx to y = -2x
We can then find y when x = -4
y = -2x
y = -2*(-4)
y = 8
V = 4/3(pi)(r^3)
V = 4/3(pi)(4.2^3)
V = 310 cm^3
Good luck!
Answer:
Since its distance do the distance formula which is d= square root of x2-x1 squared plus y2-y1 squared. Plug in the numbers. in the square root house, it will be (3-(-4)) squared plus (7-6). Since its two negatives....it will be (3+4) squared plus 1 since 7-6=1. Then it will be the square root of 7 squared plus 1. it soon will be the square root of 50. You need to break the 50 apart to a perfect square. So find a perfect number....which have 2 multiples beside itself and 1. So 25 times 2 will be it since 25 is a perfect square. 50 squared equals the square root of 25 times 2. Now break the 25. it will be 5 times the radical of 2.
