Answer:

  x = -4

Step-by-step explanation:

20 greater than (8x+5) is 8x+5+20 = 8x+25. We are told this is the value of 2x+1:

  2x+1 = 8x+25

  -24 = 6x . . . . . . subtract 2x+25

  -4 = x . . . . . . . . divide by 6

The value of x is -4.

The points (6, 9) and (0, 6) fall on a particular line. What is its equation in slope-intercept form?
SashulF [63]

Answer:

y = \frac{1}{2}x + 6

Step-by-step explanation:

Let \ (x _1  y _ 1 ) = ( 6 , 9 )  \ and  \ (x _ 2 , y _ 2 ) \  = ( 0 , 6 )\\\\

Step 1 : Find slope, m

              slope, m = \frac{y _ 2 - y _ 1}{x_ 2 - x_ 1 } = \frac{6 - 9}{0 - 6 } = \frac{-3}{-6} = \frac{1}{2}

Step 2 : Find the equation

                (y - y _ 1 ) = m ( x - x_ 1) \\\\( y - 9 ) = \frac{1}{2} (x - 6 ) \\\\y = \frac{1}{2}x - 3 + 9 \\\\y = \frac{1}{2}x + 6

Job A: $15.00 per hour (40 hours a week)​​Job B: $1,375 semi-monthly
blagie [28]

Notes before we start:

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.

Best of Luck!
