Answer:

R(16,-8)

Step-by-step explanation:

if (x1,y1) and (x2,y2) are coordinates of two points and (x,y) the coordinate of midpoint.

then x=(x1+x2)/2

and y=(y1+y2)/2

let coordinates of R are (x,y)

4=(-8+x)/2

8=-8+x

x=8+8=16

-3=(2+y)/2

-6=2+y

y=-6-2=-8

so R is (16,-8)

The sum of three consecutive odd numbers is 69. What are the three numbers?
n200080 [17]

Answer:

21, 23, 25

Step-by-step explanation:

Ok, so this one may seem a little tricky, so I'll try to explain it as best as I can. :)

So because they are consecutive odd numbers, that means they are odd numbers that are one after the other. This means each number is 2 apart from the next. So by using this, we know that there is a difference of 6 between the highest and lowest number. Now let's try and make an equation:

3o + 6 = 69

Now in order to get O by itself we have to subtract 6 from both sides:

3o = 63

Now we just have to divide by three on both sides:

o = 21

So now, we know that the lowest number is 21, but we have to add 2 to get 23, and then another 2 to get 25.

Hope this helps :)

Which ordered pair satisfies the system of equations for 3x-y=8 and x+y=2? A.) (3,-1) B.) (2.5,0.5) C.) (2.5,-0.5)(5,-3)
raketka [301]

Answer:

3x - y = 8

y = 3x - 8

y = 3*2.5 - 8 = -0.5 --> (2.5, -0.5)

y = 3*5 - 8 = 7 --> (5, 7)

Answer C is correct.
