Let number of hours needed to work = x

Multiply number of hours by rate: 15x

Add what you already have saved:

15x + 215

This needs to equal at least 800:

The equation becomes:

15x + 215 >= 800

Solve for x:

15x + 215 >= 800

Subtract 215 from both sides

15x >= 585

Divide both sides by 15

X >= 39

They have to work at least 39 hours.

Which of the points shown below are on the line given by the equation y = x?
mr_godi [17]

Answer:

think about it....y = x.....this is saying that x and y are equal

now look at point D. (-3,-3)...x = -3 and y = -3

therefore, y = x

the rest of them dont work

because on A, 1 does not equal -1

because on B, 4 does not equal 2

because on C, -3 does not equal 3

4vir4ik [10]

Answer:

286.94 cm

Step-by-step explanation:

Data:

             Area = 8,607

             b1 = 105

             b2 = 123

      Area = 1/2 * (b1 + b2) * h

      h = 2 * Area/b1 + b2

      h = 2 * 8,607/105 + 123

     h = 286.94 cm

I'm not sure if it's right but that's what my calculator gave me.
