Answer:

1. False 2. True

Step-by-step explanation:

For a geometric sequence,

\dfrac{a_2}{a_1}=\dfrac{a_3}{a_2}

1. The sequence is :

3, 13, 23, 33,...

\dfrac{13}{3}\ne \dfrac{23}{13}

It is not geometric. It is false

2. The sequence is :

5, -25, 125, -625

\dfrac{-25}{5}=\dfrac{125}{-25}\\\\-5=-5

So, the sequence is geometric as the common ratio is same. It is true.

Find the equation of the line that passes through (3,1) and is parallel to y=2x+3
ICE Princess25 [194]

Answer:

  y -1 = 2(x -3)

Step-by-step explanation:

The given equation is in slope-intercept form:

  y = mx +b . . . . line with slope m and y-intercept b

  y = 2x +3 . . . . . line with slope 2 and y-intercept 3

__

A parallel line will have the same slope. Since you are given a point, it is convenient to use the point-slope form for the equation you want:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

  y -1 = 2(x -3) . . . . . . line with slope 2 through point (3, 1)

__

<em>Additional comment</em>

If you want the slope-intercept form you can solve for y:

  y = 2(x -3) +1 = 2x -6 +1

  y = 2x -5 . . . . . slope-intercept form of the parallel line

musickatia [10]

Answer:

(1, 4.5 )

Step-by-step explanation:

The required point is at the midpoint of AB

Use the midpoint formula

Given A(4, 3) and B(- 2, 6 ), then

midpoint = [ 0.5(4 - 2), 0.5(3 + 6) ] = (1, 4.5 )
