The midpoint of GH are M(4,3) and D(5,-6). The coordinates of the endpoint are?
Phantasy [73]

Answer:

The endpoint coordinates are (3,12)

Step-by-step explanation:\frac{5+x^{2} }{2} =4 \frac{-6+y^{2} }{2} = 3

You multiply 4 by 2 which gives you 8 and write the equation5+x^{2} =8 then you subtract 5 from 8 to get 3 for the x coordinate.

You multiply 3 by 2 which gives 6 and writhe the equation-6+y^{2}=6 then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.

To check use the midpoint formula with coordinates D and your endpoint coordinates\frac{5+3}{2}=\frac{8}{2} =4 \\  \frac{-6+12}{2} =\frac{6}{2} =3 and you get the answer for the midpoint which is (4,3)

As the number of pages in a photo book increases, the price of the book also increases. There is an additional shipping charge o
wlad13 [49]

Answer:

22

Step-by-step explanation:

Solve the inequality  (20 + 0.5x) + 0.15(20 + 0.5x)   ≤ $62.10 for x:

20 + .5x + 3 + 0.75x ≤ 62.10

Combining the x terms, we get:

20 + 3 + 1.25x ≤ 62.10.

Combining the constants on the left:

23 + 1.75x ≤ 62.10

Combining the constants:

1.75x = 39.10

Solving for x:  39.10/1.75 = 22.34

Thus, the max number of whole pages she can have in her book is 22.
