Answer:

24.5

Step-by-step explanation:

Because the figure is a parallelogram, the opposite sides are equal in length.

1. Set the equations equal to each other:

JK = LM ⇒ 7x = 3x+14

2. Subtract 3x from both sides

7x = 3x+14

- 3x - 3x

___________

4x = 14

3. Divide both sides by 4

(1/4)4x = (1/4)14 ⇒ x = 3.5

4. Plug the value of x into the equation of JK

JK = 7x ⇒ JK = 7 (3.5)

5. Multiply

JK = 24.5

Answer:

Step-by-step explanation:

You have to use the triangle inequality theorem:

12cm, 4cm, xcm

x > 4cm - 12cm

x > -8cm

x < 12cm - 4cm

x < 8cm

-8cm < x < 8cm

If we look at g (x), the line hits the y-axis at -0.5. This means your y-intercept is -0.5

Hope this helps!! :)

Can someone please explain y=mx+b

lana [24]

$y=mx+b$ is slope-intercept form, which is a way of writing an equation for a line.

In this equation, $m$ represents the slope and $b$ represents the y-intercept.

$x$ and $y$ are the coordinates of a point on the resulting line.

Here are some examples:

$y=3x+2$

$y=-2x-4$

$y=8x-1$

$y=-7x+5$
