Me. Strand mowed 3/8 of his lawn. His son mowed 1/3 of it. Who mowed most of the lawn? How mush of the lawn still needs to be mowed?

Answers

3/8 * 3/3 = 9/24
1/3 * 8/8 = 8/24

So strand mowed more of the lawn.

9/24 + 8/24 = 17/24

24/24 - 17/24 = 7/24 of the lawn left

You sell 300 shares of Dendreon Corp at $8.89. You purchased the stock at $42.87. How much money did you lose?
O $42.87

42.87 if you where to multiply 300 shares by $8.89 if would give you 2,667 and if you where to subtract $42.87 from 2,667 it would give you 2,624.13 and then subtract 2,667 from 2,624.14 it would give you 42.87 and that is your answer :)

Answers

Answer:

A

Step-by-step explanation:

To move something up or down, it means we're moving along the y-axis. So we need to change the y-coordinate.

To move it up, we'll be moving towards the positive end of the y-axis. On a coordinate plane, if you move anything "up," you're moving closer to the positive end of the y-axis.

To move it five units up, we need to move 5 units positively.

So our y is:

y + 5

To move something left or right, it means we're moving it along the x-axis. So we need to change the x-coordinate.

To move it left, we'll be moving it towards the negative end of the x-axis. Think about it: on a basic number line (which is what the x-axis is), the more you move towards the left, you move closer to 0, and therefore the negative end.

To move it 2 units left, we need to move 2 units negatively.

So our x is:

x - 2

Putting them together, we have:

(x, y)

(x - 2, y + 5)

 h(x) =  -x² + 11 x + 2

Step-by-step explanation:

Explanation:-

Given that the functions are  

                                            f(x) = 2 x² - 5x -3

                                            g(x) = x² + 6x -1

               h(x)  = g(x) - f(x)

                      = x² + 6x -1 - (2 x² - 5x -3)

                     = - x² + 6 x +5x -1+3

                    = -x² + 11 x + 2

            h(x) =  -x² + 11 x + 2

Final answer:-

h(x) =  -x² + 11 x + 2
