Step-by-step explanation:

Line2

  • x - y = 3/2
  • x = y + 3/2

Line 3

  • 3x + 2y = 6
  • 3x = -2y + 6
  • x = -2/3y + 2

Line 4

  • 1/4x + y = 2
  • y = -1/4x + 2

Line 5

  • 4x - 3y = -33
  • 3y = 4x + 33
  • y = 4/3x + 11

Questions

  • 1. Yes. You need to isolate the variable to find and simplify.
  • 2. To solve for x would require to multiply all terms by 4 to get rid of fraction
  • 3. It wouldn't be easy because of the fraction. To make it easier would use multiples of 3 for x.

What is the initial value and rate of change if
Liula [17]

Answer:

Rate of change = -30

Initial value = 400

Step-by-step explanation:

Write the equation of the linear function representing this situation. Let

x = number of weeks Gandalf is spending money

y = amount of quibbles left in his account.

Gandalf has 400 quibbles in his account. This means, b=400 is the initial value of quibbles Gandalf had in his account

He spends 30 quibbles each week, this means, that he spends 30x quibbles in x weeks and the amount left in his account is

y=400-30x

Therefore, the slope is -30 and this is the rate of change (negative because the amount of money in his account decreases each week)
