4 0

Answer:

CD = 4

Step-by-step explanation:

GH bisects CF  <u><em>means</em></u>  CF = 2 CD

CF = 2 CD

⇔ 2y - 2 = 2×(3y - 11)

⇔ 2y - 2 = 6y - 22

⇔ 22 - 2 = 6y - 2y

⇔ 20 = 4y

⇔ y = 5

<u>Calculating CD ,For y = 5</u> :

CD = 3y - 11

     = 3(5) - 11

     = 15 - 11

     = 4

Marrrta [24]

Answer:

Step-by-step explanation:

t = tutoring and g = grocery store

t + g = 15......t = 15 - g

15t + 9g = 159

15(15 - g) + 9g = 159

225 - 15g + 9g = 159

-15g + 9g = 159 - 225

-6g = - 66

g = -66/-6

g = 11 <===== 11 hrs worked at the grocery store

t + g = 15

t + 11 = 15

t = 15 - 11

t = 4.....4 hrs tutoring

  • f (x) = 2x + 2
  • g (x) = 3x – 1

<u>To find:</u>

  • (f/g) (2)

<u>Solution</u>

  • (f/g)(x) = f(x)/g(x) = (2x + 2) / (3x - 1)
  • (f/g)(2) = (2*2 + 2) / (3*2 -  1) = 6/5 = 1.2
