Jason accidentally locked himself out of his apartment, but remembered that he left a window open. The window is 8 feet above th

e ground. Since he works part-time at the local hardware store, he went to the store to borrow a ladder. There's a row of bushes along the edge of the apartment, so he will have to place the ladder 6 feet from the building. What length of ladder will Jason need to reach the window?

I won't give you the answer, but I'll explain how to solve it :)

    | <Window is here, 8ft above ground

    |

    |

    |

    |

    |   _     _    _    _   _   _

                                         ^ He has to place ladder here, 6ft away from building

So you have to find the diagonal distance between the point where he has to place the ladder and where the window is. Because it creates a right triangle, you can use the Pythagorean theorem (a^2 + b^2=c^2) to find the length of the hypotenuse, or the diagonal distance. a and b are the two sides, so in this case a = 8 and b = 6. Now just square a and b, add them together to get c, and find the square root. What do you get? Feel free to ask if you're still confused.

Answer:

I Think Its 14 Feet.

Step-by-step explanation:

14 feet because the window is 8 feet high and he has to move it back 6 feet. So when you add 8 and 4 you would get the answer of 14 feet.

The solution is the point of intersection between the two equations.

Assuming you have a graphing calculator or a program to lets you graph equations (I use desmos) you simply put in the equetions and note down the coordinates of the point of intersection.

In the graph the first equation is in blue and the second in red.

The point of intersection = the solution = (-6 , -1)



If you dont have access to a graphing calculator you could draw the graphs by hand;

1) Draw a table of values for each equation; you do this by setting three or four values for x and calculating its image in y (you can use any values of x)

y = 0.5 x + 2 (Im writing 0.5 instead of 1/2 because I find its easier in this format)

x | y
-1 | 1.5 * y = 0.5 (-1) + 2 = 1.5
0 | 2 * y = 0.5 (0) + 2 = 2
1 | 2.5 * y = 0.5 (1) + 2 = 2.5
2 | 3 * y = 0.5 (2) + 2 = 3

y = x + 5

x | y
-1 | 4 * y = (-1) + 5 = 4
0 | 5 * y = (0) + 5 = 5
1 | 6 * y = (1) + 5 = 6
2 | 7 * y = (2) + 5 = 7

2) Plot these point on the graph
I suggest to use diffrent colored points or diffrent kinds of point markers (an x or a dot) to avoid confusion about which point belongs to which graph

3) Using a ruler draw a line connection all the dots of one graph and do the same for the other

4) The point of intersection is the solution

Answer:

Option C is correct

The coordinate of C' or the transformed point of C is (-6, 5)

Step-by-step explanation:

From the given graph:

In triangle ABC:

Coordinate of C is:

C(-3, 4)

The rule of transformation is given:

(x, y) \rightarrow (x-3, y+1)

We have to find the coordinate of C'.

Apply the transformation on coordinate C:

C(-3, 4) \rightarrow C'(-3-3, 4+1) = C'(-6, 5)

Therefore, the coordinate of C' is (-6, 5)
