Answer:

Equation 6x = 12.

Step-by-step explanation:

Given : 2x + 3y - 10 = 0 and 4x - 3y - 2 = 0 .

To find : When you eliminate y, what is the resulting equation.

Solution : We have given

2x + 3y - 10 = 0 -------(equation 1)

4x - 3y - 2 = 0 --------- (equation 2)

On adding both the equations.

2x + 3y - 10 = 0 .

4x - 3y - 2 = 0 .

_____________

6x + 0 - 12 = 0.

6x - 12 = 0 .

On adding both sides by 12

6x = 12.

Therefore, Equation 6x = 12.

Answer:

6x = 12

Step-by-step explanation:

2x + 3y - 10 = 0

4x - 3y - 2 = 0

add the two equations

2x + 3y - 10 = 0

4x - 3y - 2 = 0

--------------------

6x -12 = 0

add 12 to each side

6x -12 +12 = 0+12

6x =12

divide by 6

6x/6 =12/6

x =2

Right triangles abc and dbc with right angle c are given below. If cos(a)=15,ab=12 and cd=2, find the length of bd.

dmitriy555 [2]

see the attached figure to better understand the problem

we have that

$cos(A)=\frac{1}{5} \\ AB=12\ units\\ CD=2\ units$

Step 1

Find the value of AC

we know that

in the right triangle ABC

$cos (A)=(AC/AB)\\AC=AB*cos(A)$

substitute the values in the formula

$AC=12*(1/5)\\ AC=2.4\ units$

Step 2

Find the value of BC

we know that

in the right triangle ABC

Applying the Pythagorean Theorem

$AB^{2} =AC^{2}+BC^{2}\\ BC^{2}=AB^{2} -AC^{2}$

substitute the values

$BC^{2}=12^{2} -2.4^{2}\\BC^{2}= 138.24\\ BC=11.76\ units$

Step 3

Find the value of BD

we know that

in the right triangle BCD

Applying the Pythagorean Theorem

$BD^{2} =DC^{2}+BC^{2}$

substitute the values

$BD^{2} =2^{2}+11.76^{2}$

$BD=11.93\ units$

therefore

the answer is

the length of BD is 11.93 units
