Answer:

Step-by-step explanation:

We can see that for every time x changes by 2, y changes by 6

The rate of change is what will happen to y if you change x by one. To find this we take 6/2 and get 3.

Find the value of KL.<br> KL= 3x + 2 and LM= 5x - 10

Mariana [72]

From the given graph, we can tell kl=lm

therefore,

3x + 2 = 5x - 10

3x+2-2=5x-10-2

subtract 2 from both sides.

3x+ 0 =5x-12 3x=5x-12

3x-5x=5x-5x-12

subtract 5x from both sides.

-2x=0-12 -2x=-12 (-2x)/-2=-12/-2

divide both sides by -2.

1x= 6 -12/-2=6

and of course the -2 and -2 cancel on left side leaving 1x.

x=6

KL = 3x+2 = 20 units

1). Linear Combination (SHOW WORK)

Georgia [21]

Answer:

Part 1) The solution of the system of equations is (2,-5)

Part 2) The solution of the system of equations is (2,4)

Step-by-step explanation:

Part 1) Linear combination

we have

$3x+2y=-4$ -----> equation A

$4x-y=13$ -----> equation B

Multiply equation B by 2 both sides

$2(4x-y)=2*13$

$8x-2y=26$ -----> equation C

Adds equation A and equation C

$3x+2y=-4\\8x-2y=26\\-------\\3x+8x=-4+26\\11x=22\\x=2$

Find the value of y

$3(2)+2y=-4$

$2y=-4-6$

$2y=-10$

$y=-5$

The solution of the system of equations is (2,-5)

Part 2) By graph

$y=(1/2)x+3$ -----> equation A

$-3x+y=-2$ -----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

The intersection point is (2,4)

therefore

The solution of the system of equations is the point (2,4)
