I need help with 7-13.

7. x-intercept:0 y-intercept:0

8. x-intercept:-8 y-intercept:8

9. x-intercept:-2 y-intercept:6

10. x-intercept:3 y-intercept:9

11. x-intercept:6 y-intercept:4

12. x-intercept:5 y-intercept:-2

13. x-intercept:12 y-intercept:8

The x-intercept represents the amount of books you can buy if you don't buy any movies and the y-intercept represents the amount of movies you can buy if you don't buy any books

Step-by-step explanation:

Step 1: Understand question

The x-intercept is the x value when y is equal to zero and the y-intercept is the y value when x is equal to zero

Step 2: Solve

7. y = 2(0)

   y = 0

   (0) = 2x

   x = 0

8. y = (0) + 8

   y = 8

   (0) = x + 8

  -8 = x

9. y = 3(0) + 6

   y = 0 + 6

   y= 6

   (0) = 3x + 6

   -6 = 3x

    x = -2

10. 3(0) + y = 9

    0 + y = 9

     y = 9

     3x + 0 = 9

     x = 3

11. 2(0) + 3y = 12

    0 + 3y = 12

     y = 4

    2x + 3(0) = 12

    2x + 0 = 12

     x = 6

12. 2(0) - 5y = 10

       0 - 5y = 10

        y = -2

       2x - 5(0) = 10

       2x- 0 = 10

       x = 5

13. 8x + 12y = 96

     8(0) + 12y = 96

      12y = 96

       y = 8

     8x - 12(0) = 96

      8x = 96

       x = 12

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
