Simplifying
13 = 4x + 9

Reorder the terms:
13 = 9 + 4x

Solving
13 = 9 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.
13 + -4x = 9 + 4x + -4x

Combine like terms: 4x + -4x = 0
13 + -4x = 9 + 0
13 + -4x = 9

Add '-13' to each side of the equation.
13 + -13 + -4x = 9 + -13

Combine like terms: 13 + -13 = 0
0 + -4x = 9 + -13
-4x = 9 + -13

Combine like terms: 9 + -13 = -4
-4x = -4

Divide each side by '-4'.
x = 1

Simplifying
x = 1

Igualacion. <br><br>x-y=3. 2x-3y=4​
Delicious77 [7]

Answer:

x - y = 3

2x - 3y = 4

Igualación

Despejamos una de las incógnitas en cada ecuación e igualamos. (En este caso la x)

3y + 4

x = y + 3 x = ---------------

2

3y + 4

y + 3 = ---------------

2

2 (y + 3 ) = 3y + 4

2y + 6 = 3y + 4

se pasan las incógnitas a un lado y lo que cambia de lado se cambia de signo

3y - 2y = 6 - 4 ⇒ y = 2

sustituimos el valor de y en cualquiera de las dos para obtener el valor de x

x - 2 = 3 ⇒ x = 5

Solución

x = 5

y =2

What is the volume of the cone below?
Elden [556K]

Answer:

V = 3408 pi  unit^3

Step-by-step explanation:

Volume  of a cone is given by

V = 1/3 pi r^2 h

We know the radius is 12 and the height is 71

V = 1/3 * pi * (12)^2 *71

V = 1/3 * pi * 144 *71

V = 3408 pi  unit^3

What is the equation of the line that is parallel to the given line and passes through the point (–2, 2)?
kari74 [83]
Let the equation of the given line be y=mx+a. This line has slope m and the parallel line will have the same slope.
Then the equation of the parallel line to the line y=mx+a will be y=mx+b. Since line <span>passes through the point (–2, 2), the coordinates of this point suit the equation:
</span><span>
</span><span>2=m·(-2)+b,</span>
2=-2m+b,
b=2+2m 
and the equation is y=mx+2m+2. 
You should only to paste correct m from the given equation.
