Sistema de ecuaciones.5x+2y=-152x-2y=-6
Zolol [24]

Tnemos el sisema de ecuaciones:

\begin{gathered} 5x+2y=-15 \\ 2x-2y=-6 \end{gathered}

Podemos resolverlo por eliminación sumando ambas ecuaciones y eliminando y. Asi podemos resolver para x:

\begin{gathered} (5x+2y)+(2x-2y)=(-15)+(-6) \\ 7x+0y=-21 \\ x=-\frac{21}{7} \\ x=-3 \end{gathered}

Ahora podemos resolver para y con cualquiera de las dos ecuaciones:

\begin{gathered} 2x-2y=-6 \\ 2\cdot(-3)-2y=-6 \\ -6-2y=-6 \\ -2y=-6+6 \\ -2y=0 \\ y=0 \end{gathered}

Respuesta: x=-3, y=0

The difference between two numbers is 2790. If the smaller number is 3560, what is the other number?
8090 [49]

Answer:

the other number is 6350

Step-by-step explanation:

given data

difference between two numbers = 2790

smaller number = 3560

to find out

the other number

solution

we consider here larger number  = x

smaller number  = y

so

so difference between two number is express as

difference between two number = x - y    ....................1

put here value and we get another number i.e large number

2790 = x - 3560

solve it we get

x = 6350

so the other number is 6350

KonstantinChe [14]

Answer:

\sqrt32

Step-by-step explanation:

You use the Pythagorean theorem since a triangle is formed.

a^{2} +b^{2} =c^{2}

6^{2} = 2^{2} +x^{2}

36-4 =x^{2}

x= \sqrt{32}
