I need help on this question ​

Mathematics
1 answer:
Sedbober [7]3 years ago
3 0

Answer:

Step-by-step explanation:

It would be answer b, because if you were to solve this, then this is how you would do it (in the most effecient way):

2.5x + 1.2 = 1.2x + 4.2

2.5x + 1.2 - 1.2 = 1.2x + 4.2 - 1.2

2.5x = 1.2x + 3

2.5x - 1.2x = 1.2x - 1.2x + 3

1.3x = 3

1.3x/1.3 = 3/1.3

x = 3/1.3

Given that lines AB and DE are parallel,determine how triangles ABC and EDC can be shown to be similar
Roman55 [17]

Answer:

The transversals cutting through the parallel lines create angles that are congruent to one another. Angles 1`and 5 are alternate interior and are congruent. Angles 2 and 6 are alternate interior and are congruent. And of course if 2 of 3 angles in 2 triangles are congruent, then the 3rd angles have to be congruent as well.  HOWEVER, we can see that the sides are NOT congruent, and we need at least one side to prove congruency.  Since we have 3 congruent angles, we can only say they are similar.

Write an equation of the line, in slope-intercept form, that passes through (-2, 5) and (1, -1).
djyliett [7]

Answer:

y = -2x + 1

Step-by-step explanation:

<u>Formulae:</u>

<u />

Slope: m=\frac{y_2-y_1}{x_2-x_1}\\

  • m = slope
  • y₂ = second y-value
  • y₁ = first y-value
  • x₂ = second x-value
  • x₁ = first x-value

Point-slope form: y-y_1=m(x-x_1)

  • y₁ = first y-value
  • m = slope
  • x₁ = first x-value

Slope-intercept form: y=mx+b

  • m = slope
  • b = y-intercept value

<u>Calculations:</u>

<u />

<u />m=\frac{-1-5}{1-(-2)}\\m=\frac{-6}{3}\\m=-2<u />

<u />

<u />y-5=-2(x-(-2))\\y-5=-2(x+2)\\y-5=-2x-4\\y=-2x+1<u />
