Answer:

18m

Step-by-step explanation:

Since the given traingles are similar

We get

\frac{JK}{MN} =  \frac{KL}{ML}

\frac{JK}{42}  =  \frac{21}{49}

JK =  \frac{21 \times 42}{49}

JK =  \frac{3 \times 7 \times 6 \times 7}{7 \times 7}

JK = 3 \times 6 = 18

JK = 18

Hence the distance across river is 18m

A) {y=2x
sladkih [1.3K]

We can see that

both lines intersects at origin

so, the solution is x=0 and y=0

now, we will check each options

option-A:

y=2x

y=-4x

now, we can set them equal

and then we can solve for x

-4x=2x

6x=0

x=0

now, we can find y

y=2*0

y=0

so, solution is x=0 and y=0

so, this correct...........Answer

observe as seguintes situações e sua representação em linguagem matematica dois numeros x e y são tais 2x y=6 x-y=3
agasfer [191]

Answer:

The value of x any y are "-5.29 and 0.79" and "3.79 and -2.29"

Step-by-step explanation:

Given values:

2xy =6.....(a)\\\\x-y= 3.....(b)\\\\

After solve equation (a) we get

\ equation: \\\\2xy= 6\\\\xy =\frac{6}{2} \\\\xy = 3.....(x)\\\\

After solve equation (b) we get

\ equation: \\\\x-y =3\\\\x= 3+y....(x1)\\

put the value of x in to equation (x)

(3+y)y = 3\\

y^2+3y-3=0\\\\\ compare \ the \ value \ with \ ay^2+by+c=0\\a= 1\\b=3\\c=-3\\\ Formula: \\y= \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\y= \frac{-3\pm \sqrt{9+12}}{2}\\y= \frac{-3\pm \sqrt{21}}{2}\\

The value of y is = -5.29 and 0.79, put the value of y in x1 equation so, we get: 3.79 and -2.29
