Choice B

Step-by-step explanation: Hello!

To find the length of KL, we will need to use the distance formula.

The distance formula is \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}.

We are given K(4, 5) and L(4, -2), and we can find the distance between these two points through substitution.

\sqrt{(4-4)^{2} +(-2-5)^{2}}

\sqrt{(0)^{2} +(-7)^{2}}

\sqrt{(7)^{2}} = \sqrt{49} = 7

Therefore, the length of KL is 7 units, choice B.

3) The length of JM is 9x + 6 units, the length of JK is
Vlada [557]

Answer:

JM = 60 units

Step-by-step explanation:

Given:

JM = 9x + 6

JK = 5x

KM = 3x + 12

JK + KM = JM (segment addition postulate)

(5x) + (3x + 12) = (9x + 6) (substitution)

Solve for x

5x + 3x + 12 = 9x + 6

Collect like terms

5x + 3x - 9x = -12 + 6

-x = -6

Divide both sides by -1

x = 6

JM = 9x + 6

Plug in the value of x

JM = 9(6) + 6

JM = 54 + 6

JM = 60 units

g100num [7]
4x-5=31

Add 5 to both sides
4x=36

Divide both sides by 4
x=9

Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept. Her graph is shown.
blagie [28]
The problem statement says "the graph is shown," but you haven't shared it.  Please do that if possible.  Thank you.

<span>Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept.

We can quickly put this into slope-intercept form:  
                                                                                                 12 - 2x
Subtract 2x from both sides:  2x - 2x + 4y = 12 - 2x  =>   y = ------------ 
                                                                                                      4

In simplest form, this is y = 3 - (1/2)x, or (-1/2)x + 3.  The slope is -1/2 and the y-intercept is (0,3).</span>
