Answer:

<h3>             True</h3><h3>fo example:  3•3 = 9 (=2•4+1)</h3><h3>                      5•7 = 35  (=2•17+1)</h3><h3>                     11•13 = 143  (=2•71+1)    </h3>

Step-by-step explanation:

If k is any integer then 2k is even number and 2k+1 is odd number

If n is any other integer then 2n+1 is also some odd number

Their product:

(2k + 1)(2n + 1) = 2k•2n + 2•1k + 1•2n + 1•1 = 2(2kn + k + n) + 1

k,n are integers so 2kn also is integer.

Sum of integers is integer too, so if we name 2kn+k+n = z, then product of any two odd integers is 2z+1 which is an odd number.

If q is the midpoint of segment PR, find the coordinates of R if P (11,-2) and Q (4,3) ​
Murrr4er [49]

Answer:

  R(-3, 8)

Step-by-step explanation:

R = 2Q -P

R = 2(4, 3) -(11, -2) = (8-11, 6+2)

R = (-3, 8)

_____

You can derive the formula for the endpoint from the formula for the midpoint:

  Q = (R + P)/2

  R = 2Q - P . . . . . . multiply by 2 and subtract P

Answer:

hi

Step-by-step explanation:

{5}^{2}  +  {x}^{2}  =  {7}^{2}  \\ 25 +  {x}^{2}  = 49 \\  {x}^{2}  = 49 - 25 \\  {x}^{2}  = 24 \\ x =  \sqrt{24}

What are the intercepts of the line 2x + 4y = 12?
Darina [25.2K]
<span>if you're finding the x intercept, y is ALWAYS 0, so in this, you can just get rid of the -4y because you know that it's 0, so you're left with 2x=12 divide by 2 on both sides so you find x intercept is (6,0) on the graph 
the y works the same way, if you're looking for the y, you know that the x is zero, so you're left with -4y=12, divide by -4y on both sides and you end up with the y intercept being (0,-3) 

x int.= (6,0) 
y int.= (0,-3) 

by the way, when it's written like that, it's called standard form, so to find the intercepts on 2x=12+4y, you'd have to convert it into standard form (Ax=By=C) so you subtract 4y on both sides to make it 2x-4y=12, and then once you have it like that you can do the math to find the y and x intercepts.
