Jayne Haydack's weekly salary at Charter Network is $500 plus 15% commission on her weekly sales. Which of the following functions is expressing Jayne's weekly salary. y = 500x + 15 y = 15x + 500 y = 500x + 0.15 y = 0.15x + 500

9514 1404 393

  y = 0.15x + 500

Step-by-step explanation:

Jayne's salary equation will be of the form ...

  salary = commission + base wage

Letting y represent Jayne's salary, and x her sales amount, we can write this as ...

  y = (15%)x +500

Of course, 15% = 0.15, so this is ...

  y = 0.15x +500 . . . . . matches the last choice

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
