(9, 8) is the midpoint of mc136-1.jpg. The coordinates of S are (10, 10). What are the coordinates of R?
kolbaska11 [484]
I cant see the image...but I take it that the midpoint is (9,8) and the endpoint S is (10,10) and ur looking for the other endpoint R.

midpoint formula : (x1 + x2) / 2, (y1 + y2) / 2
(10,10)....x1 = 10 and y1 = 10
(x,y)....x2 = x and y2 = y
so we sub
(10 + x) / 2, (10 + y) / 2 = 9/8

(10 + x) / 2 = 9
10 + x = 9 * 2
10 + x = 18
x = 18 - 10
x = 8

(10 + y) / 2 = 8
10 + y = 8 * 2
10 + y = 16
y = 16 - 10
y = 6

so endpoint R has coordinates of (8,6) <===

I need help with 1-9 please!

1-First let’s list the numbers between 210 to 220, except the even ones since they’re a multiple of 2:

211; 213; 215; 217; 219

Let’s remove 213, and 219 because they’re multiples of 3 (2+1+3=6; 2+1+9=12), 215 is multiple of 5, so let’s remove it.

That leave’s is with 211, and 217.

We can remove 217, because it’s a multiple of 7, leaving us with 211.

2- It’s deductive reasoning, because you started with a more general idea.

3- {-7, -6, -5, -4, -3, -2, -1, 0, 1}

4- {x e R, x>=-2}

5-{-1, 0, 1}

6- {x∣-4≤ x ≤6}

7- [-20, ♾ )

8- On a number line, make a circle around -1, and continue the line to minus infinity.

9- On a number line, make a circle on -3, and continue to minus infinity. Make a ring on 0, and continue to infinity.
