Hm..Maybe so that when they give birth the stretch Mark's on their body wont be so bad.
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:
x=6
Step-by-step explanation:
Answer:
x= 5.55 and 0.45
Step-by-step explanation:
Quadratic Equation = (-b±√b²-4(a)(c))÷2(a)
Get equation = to 0 by subtracting the 3 on the right side of the = sign
2x² - 12x + 5
Identify the variables
a=2
b=-12
c=5
Put them into the quadratic equation
(-(-12)± √-12² - 4(2)(5))÷2(2)
Simplify
(12 ±√144 - 40)÷4
(12±√104)÷4
Now split into 2 equations (one with addition one with subtraction) because of the ± then continue simplifying
(12 - √104)÷4 (12 + √104)÷4
(12 - 10.198039)/4 (12 + 10.198039)/4
5.54950975 0.45049025
Round
5.55 0.45
