En un experimento de laboratorio se mezcla dextrosa y agua en varios recipientes, con la condición de que la concentración de de

xtrosa debe ser igual en todos los recipientes.
Juan tiene un recipiente que contiene 18dl de agua;
Pedro tiene un recipiente que contiene 10dl de agua;
David tiene un recipiente que contiene 8dl de agua;
Isabel tiene un recipiente que contiene 20dl de agua;
Berta tiene un recipiente que contiene 16dl de agua;
Laura tiene un recipiente que contiene 6 dl de agua.


El resultado es el siguiente:


Juan agrega al recipiente 45 g de dextrosa;
Pedro agrega al recipiente 25 g de dextrosa;
David agrega al recipiente 20 g de dextrosa;
Isabel agrega al recipiente 50 g de dextrosa;
Berta agrega al recipiente 35 g de dextrosa;
Laura agrega al recipiente 15 g de dextrosa.


En la experiencia, uno de los participantes ha cometido un error. ¿Quién se ha equivocado?

Write the equation in slope-intercept form of the line that has a slope of 2 and contains
mina [271]

Equation in slope-intercept form is y = 2x - 6

Step-by-step explanation:

  • Step 1: Given slope of the line, m = 2. Form an equation y = mx + b

⇒ y = 2x + b ---- (1)

  • Step 2: The line passes through the point (4,2). So it will satisfy the equation. Find b by substituting x = 4 and y = 2.

⇒ 2 = 2 × 4 + b = 8 + b

⇒ b = -6

  • Step 3: Form the slope-intercept equation.

⇒ y = 2x - 6

Find the values of k so that each remainder is three. <br> 10. (x^2+ 5x + 7) = (x + k)
Goryan [66]

Answer:

k=1\text{ or } k=4

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a <em>binomial</em> in the form (x - a), then our remainder will be P(a).

We are dividing:

(x^2+5x+7)\div(x+k)

So, a polynomial by a binomial factor.

Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.

We want our remainder to be 3. So, P(a)=P(-k)=3.

Therefore:

(-k)^2+5(-k)+7=3

Simplify:

k^2-5k+7=3

Solve for <em>k</em>. Subtract 3 from both sides:

k^2-5k+4=0

Factor:

(k-1)(k-4)=0

Zero Product Property:

k-1=0\text{ or } k-4=0

Solve:

k=1\text{ or } k=4

So, either of the two expressions:

(x^2+5x+7)\div(x+1)\text{ or } (x^2+5x+7)\div(x+4)

Will yield 3 as the remainder.
