Plug in -3 for x and you get -21=-6+3k which you can further solve to be 3k=-27 and so k must be -9

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

Help me please<br> 8. Match each angle pair with the corresponding drawing. Choose the best answer!
sdas [7]

Answer:

1. D

2. B

3.  A

4. C

Step-by-step explanation:

1. Vertical angles are a pair of opposite angles formed by the intersection of lines. Choice D has two lines intersecting, and two opposite angles formed by it.

2. Adjacent angles are two angles that have a common vertex and common side but do not overlap. Choice B is two angles with a common vertex and common side, and they don't overlap.

3. Supplementary angles are angles that add up to 180 degrees/make a straight angle. Choice A has two angles that add up to 180 degrees, and the two angles combined make a straight angle/line.

4. Two angles are called complementary angles if they add up to 90 degrees and form a right angle. Choice C has two angles that form a right triangle, meaning it adds up to 90 degrees.

Please help. I need help with my math homework and I’m confused and I only have one attempt. Thanks in Advance!
Marrrta [24]

Answer:

x>-6, x<-4

Step-by-step explanation:

|x+5|>-1

x+5>−1 (Possibility 1)

x+5−5>−1−5 (Subtract 5 from both sides)

x>−6

x+5<−(−1)(Possibility 2)

x+5<1(Simplify both sides of the inequality)

x+5−5<1−5(Subtract 5 from both sides)

x<−4

x>-6 or x<-4
