Given : Point (5,-3)    

To find : The reflection image of given point  across the line ?

Solution :        

The reflection across the line   is when both the coordinated changes its sign and position.

i.e, (x,y) across y=-x line became (-y,-x)    

So, The point (5,3) reflection image across the line is (3,-5).

Answer:

r = R - ( 43 + 23 )

There is no more space in his backpack.

Step-by-step explanation:

Jimmy's backpack has a space of 60 cubic liters (R).

Now, he has a pile of equipment of volume 43 cubic liters and then he has his sleeping bag of volume 23 cubic liters.

Now, if r is the amount of room left in his backpack, the equation I can use

r = R - ( 43 + 23 ) ....... (1) to determine if he has enough room in his backpack.

Now, in our case R = 60 cubic liters

Therefore, from equation (1), we get r = 60 - ( 43 + 23 ) = - 6, i.e. there is no more space in his backpack. (Answer)
