Match this system of linear equations to the correct description of its solution set. y= -8x - 20
y= -8x - 20

A) one solution
B) no solutions
C) an infinite amount of solutions

An infinite set of solutions (C)

Step-by-step explanation:

Since the slopes and Y intercepts are the same, the lines are on top of each other, which means there's an infinite amount of solutions.

C) an infinite amount of solutions

Step-by-step explanation:

[1]    y + 8x = -20

  [2]    y + 8x = -20

Solve by Substitution :

// Solve equation [2] for the variable  y

  [2]    y = -8x - 20

// Plug this in for variable  y  in equation [1]

[1]    (-8x-20) + 8x = -20

  [1]    0 = 0 =>  Infinitely many solutions

step-by-step explanation:

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
