Answer:

x = 14/3

Step-by-step explanation:

4(2x-3)+8(x-4)=2(2x+6)

Distribute

8x -12 +8x - 32 = 4x +12

Combine like terms

16x -44 = 4x+12

Subtract 4x

16x-4x -44 = 4x+12-4x

12x -44 =12

Add 44 to each side

12x-44+44 = 12+44

12x = 56

Divide each side by 12

12x/12 = 56/12

x = 14/3

Answer:

x=\dfrac{14}{3}

Step-by-step explanation:

4(2x-3)+8(x-4)=2(2x+6)

Expand parentheses:

8x-12+8x-32=4x+12

Combine similar terms:

16x-44=4x+12

Subtract 4x and add 44 to both sides:

12x=56

Divide both sides by 12:

x=\dfrac{14}{3}

Hope this helps!

Slope 6; through (0,4)
Agata [3.3K]

Answer:

Y=6X+4

Step-by-step explanation:

Para este ejercicio solo disponemos de dos datos conocidos que son la pendiente que es 6 y un punto de la recta (0,4)

Para hallar la ecuación de la recta usaremos la conocida ecuacion punto pendiente:

Y-Yo=m(X-Xo)

Donde Xo y Yo son respectivamente las coordenadas del punto dado (0,4)

Xo=0

Yo=4

m=6----> m es la pendiente

Entonces remplazamos

Y-4=6(X-0)------>Remplazamos los valores dados

Y-4=6X-0-------->Destruimos los parentesisi aplicando distributiva

Y=6X+4 ----------->Finalmente despejamos el 4 que acompaña a la Y

The graph of a quadratic function has x intercepts at -3 and 5/2, and y intercept at 10. Give the function.
sesenic [268]

Answer:

  f(x) = -4/3x² -2/3x +10

Step-by-step explanation:

The quadratic regression function of a graphing calculator or spreadsheet can determine the equation for you.

___

Or, you can determine it yourself.

The equation can be written in the form ...

   f(x) = a(x +3)(x -5/2) . . . . . . . using the given x-intercepts

for some value of "a"

For x = 0, this must match the y-intercept.

  f(0) = a(0 +3)(0 -5/2) = 10

  -15/2·a = 10

  a = -20/15 = -4/3

So, the function can be written as ...

  f(x) = (-4/3)(x +3)(x -5/2)

or

  f(x) = -4/3x² -2/3x +10

Please help me for solve x
dlinn [17]

Answer:

X =6

Step-by-step explanation:

Angles on a straight line add up to 180°

180-110=70

The 70° is the same on the angles above

70+8+17x=180

180-70=110

110-8=102

102/17=6

X=6
