Solve by elimination. 4x+6y=-12 2x+3y=4

Mathematics
1 answer:
MrRa [10]3 years ago
5 0

Answer:

0 = 20 is false, therefore the system of equations has no solution.

NO SOLUTION

Step-by-step explanation:

Given the system of equations

\begin{bmatrix}4x+6y=-12\\ 2x+3y=4\end{bmatrix}

solving the system by the elimination method

\begin{bmatrix}4x+6y=-12\\ 2x+3y=4\end{bmatrix}

\mathrm{Multiply\:}2x+3y=4\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:4x+6y=8

\begin{bmatrix}4x+6y=-12\\ 4x+6y=8\end{bmatrix}

subtracting the equations

4x+6y=8

-

\underline{4x+6y=-12}

0=20

0 = 20 is false, therefore the system of equations has no solution.

NO SOLUTION

The hypotenuse of a right angle triangle is 13cm.if one other side of the triangle is 1cm shorter than the hypotenuse.calculate
Alona [7]
<h3><u>Given</u><u>:</u><u>-</u></h3>

  • The hypotenuse of a right angle triangle is 13cm.

  • One other side of the triangle is 1cm shorter than the hypotenuse.

<h3><u>To</u><u> </u><u>find</u><u> </u><u>out</u><u>:</u><u>-</u></h3>

Find the third scale of the triangle .

<h3><u>Solution:-</u><u> </u></h3>

Let the third Side be x.

According to the question,

★ Hypotenuse = 13 cm

★ Other side = Hypotenuse - 1 [ Given ]

= 13 cm - 1 cm

= 12 cm

Now,

<u>By pythagoras theorem</u>,

13² = 12² + x²

⇒ 169 = 144 + x²

⇒ x² = 169 - 144

⇒ x² = 25

⇒ x = √25

⇒ x = 5 cm

Hence, the third scale of the triangle is 5 cm.

Find the area of the following shape:
lara31 [8.8K]

9514 1404 393

Answer:

  77 in²

Step-by-step explanation:

The area of a triangle is given by the formula ...

  A = (1/2)bh

For your triangle, with its base of 14 inches and height of 11 inches, the area is ...

  A (1/2)(14 in)(11 in) = 77 in²

_____

<em>Additional comment</em>

The side lengths added to the figure are incorrect. If we take the 11.5 to be correct, then the left side is about 15.3.
