given the equation y= - 3x + 2.5 answer the following when X is 1 what value of Y makes the equation true part B when x is -1.5 what value of y makes the equation true? part c when y is 8.5 what value of x makes the equation true

Respuesta :

Answer:

  • y = -0.5
  • y = 7
  • x = -2

Step-by-step explanation:

Fill in the given values and solve for the remaining variable.

a) y = -3(1) +2.5

  y = -0.5

__

b) y = -3(-1.5) +2.5 = 4.5 +2.5

  y = 7

__

c) 8.5 = -3x +2.5

  6 = -3x . . . . subtract 2.5

  -2 = x . . . . . divide by -3
