Answer:

2 ± i

Step-by-step explanation:

by 5, I assume you mean +5

x² - 4x + 5 = 0

x = (-b±(√(b²-4ac)) / 2a

x = (4 ± (√(16 - 20)) / 2

x = (4 ± (√(-4)) / 2

√-4 = √4√-1 which is 2i

x = (4 ± 2i) / 2

x = 2 ± i

50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?​
kirill115 [55]

Answer:

  • B. y = 3x

Step-by-step explanation:

Use one of the points on the graph to find the equation.

Let's take the point (1,3)

<u>We know the proportional relationship is:</u>

  • y = kx, where k is the coefficient of proportionality

<u>Substitute the values from the point and solve for k:</u>

  • 3 = 1*k
  • k = 3

<u>The function is:</u>

  • y = 3x

Correct choice is B
