Answer:

12 movies

Step-by-step explanation:

If you do not rent any vidoes you will be charged $45 no matter what, so...

Movies + 45 = total charge

each movie is 1.99 and you owe (total charge) $68.88

equation:

1.99x + 45 = 68.88

          -45       -45    (subtract 45 from each side to keep equation balanced)

1.99x = 23.88  (now divide both sides by 1.99 to get x alone)

     x = 12

you rented 12 movies

Factor 6a2 - 23a - 4.
rusak2 [61]

Answer:

(6 a + 1) (a - 4)

Step-by-step explanation:

Factor the following:

6 a^2 - 23 a - 4

Factor the quadratic 6 a^2 - 23 a - 4. The coefficient of a^2 is 6 and the constant term is -4. The product of 6 and -4 is -24. The factors of -24 which sum to -23 are 1 and -24. So 6 a^2 - 23 a - 4 = 6 a^2 - 24 a + a - 4 = a (6 a + 1) - 4 (6 a + 1):

a (6 a + 1) - 4 (6 a + 1)

Factor 6 a + 1 from a (6 a + 1) - 4 (6 a + 1):

Answer:  (6 a + 1) (a - 4)

De qué manera relacionas lo que escuchas o lees en tu vida​
nika2105 [10]

Answer:

La forma en que relaciono lo que escucho o leo en mi vida es a través de la interpretación de la información, es decir, todo aquello que leo o escucho es procesado, evaluado e interpretado conforme a mi experiencia, vivencias, estudios e ideología, lo que me permite obtener una conclusión de la información que percibo.

Así, no considero todo lo que leo y escucho como hechos comprobados, sino que lo someto a un análisis exhaustivo y completo respecto de su validez y sus implicancias respecto de mi persona.

Please help with this question
svetlana [45]

Answer:

Segment JK is a chord in circle H

Line LM is a secant to circle H

Step-by-step explanation:

* Lets revise some definition in the circle

- The radius of the circle is a line segment drawn from the center of  

 the circle to a point on the circumference of the circle

- The chord of a circle is a line segment whose endpoints lie on the

 circumference of the circle

- The secant is a line intersect the circle in two points

- The tangent is a line touch or intersect the circle in one point

* Now lets solve the problem

- In circle H

∵ JK is a segment in circle H

∵ Point J lies on the circumference of circle H

∵ Point K lies on the circumference of circle H

∴ Segment JK is a chord in circle H

∵ LM is a line

∵ LM intersect circle H in two points L and M

∴ Line LM is a secant to circle H
