Answer:
Step-by-step explanation:
x = 55
x + 55 = 110
x + 20 = 75
x + 65 = 120
Part A:
C= a + bn
Make the two equations out of the words:
82 = a + b100 * 2.5 = 205 = a + b250
157 = a+ b250
Subtract the two,
205 = a + b250
- ( 157 = a + b250)
48 = a
Find b by substituting in a:
82 = a + b100
82 = 48 + b100
34 = b100
b = 0.34
Answer for part a: a = 48 , b = 0.34
Part B:
C = a +bn <- when n = 300 , put in a and b, then solve
C = 48 + 0.34(300)
C = 48 + 102
C = 150

Answer:
y = -3x; the const. of prop. is -3.
Step-by-step explanation:
Recall: a proportional relationship satisfies y = kx, where k is the constant of proportionality.
In this particular example we see that (-3)(-2) = 6, (-3)(1) = -3, and (-3)(2) = -6.
This confirms adherence to the equation of a proportional relationship. The constant of proportionality here is -3.
The function governing the table is y = -3x.
