Which is the greatest value in the range of y=-5x+3 for the domain {-2, 0, 1, 3}?

Answers

Put the values for the domain in for x, and see what values for y are generated 

x = - 3 --> y = -17 

x = - 1 --> y = - 7 

x = 0 --> y = - 2 

x = 1 --> y = 3 

x = 3 --> y = 13 

so the answer is "C"

Hope that helped!

Final answer:

The greatest value in the range of y=-5x+3 for the given domain {-2, 0, 1, 3} is 13 when x = -2.

Explanation:

The greatest value in the range of y = -5x + 3 for the domain {-2, 0, 1, 3} can be found by substituting each value of x into the equation and calculating the corresponding y value. The highest y value represents the greatest value in the range. Let's calculate:

  1. For x = -2, y = -5(-2) + 3 = 13
  2. For x = 0, y = -5(0) + 3 = 3
  3. For x = 1, y = -5(1) + 3 = -2
  4. For x = 3, y = -5(3) + 3 = -12

Therefore, the greatest value in the range is 13 when x = -2.

Angle x is 100 degrees because the opposite angle is 80 degrees and they must add up to 180 degrees.
Angle X is 100 degrees because when you are adding up to 180 degrees, subtract the angle you already know from 180 and you will have your answer. 100 degrees
