<span>(u + 7) + 13 = u + (7 + 13) The associative property of addition says that you can add numbers regardless of how they're grouped and get the same result. So let's look at the options and see what makes sense. (u + 7) + 13 = u + (7 + 13) * This is showing the associative property like the definition states. So this is the correct choice. 21 + 2y = 2y + 21 * This is a demonstration of the commutative property of addition. So it's the wrong choice for this question. 3â‹…(5â‹…x)=(3â‹…5)â‹…x * This is showing the associative property of multiplication. So it's the wrong choice for this question. If m + 3 = 18, then 18 = m + 3. * This is a demonstration of the symmetric property of equality. So for this question, it's the wrong choice.</span>

Step-by-step explanation:

al nth term:

numerator:

=  {n}^{2}

denominator:

= n + 1

so nth term :

=  \frac{ {n}^{2} }{n + 1}

b). 1; 11; 27; 49

first difference: 10; 16; 22

second difference :6

formula for 1st difference:3a+b

formula for 2nd difference:2a

Therefore:

2a=6

a=3

3a+b=10

sub in a

3(3)+b=10

9+b=10

b=1

sub into quadratic formula

{an}^{2}  + bn  + c

(3) {(1)}^{2}  + (1)(1) + c = 1

3(1) + 1 + c = 1

3 + 1 + c = 1

4 + c = 1

c  = - 3

So Tn:

3 {n }^{2}  +  1n - 3

Answer:

C

Step-by-step explanation:

Given Coordinates:

(-4, -2), (2, -2), (4, 2), (-2, 2)

The shape that uses the coordinates (-4, -2), (2, -2), (4, 2), (-2, 2) would make a parallelogram.

See graph for answer:

So correct choice is C.

Quadrilateral PUMA has coordinates at P(-5,-2), U(-1,2), M(4,-3), A(0,-7) and it is transformed by (x+3,y-5). Determined the ima
IgorLugansk [536]

The image of M is (7 , -8)

Step-by-step explanation:

Let us revise some transformation

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units  then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units  then its image is (x , y - k)

∵ The quadrilateral PUMA has coordinates at:

   P (-5 , -2) , U (-1 , 2) , M (4 , -3) , A (0 , -7)

∵ It is transformed by (x + 3 , y - 5)

- That means the quadrilateral translated 3 units right and 5 units

   down, then we add each x-coordinate by 3 and subtract 5 from

   each y-coordinate

∵ The coordinates of point M are (4 , -3)

∴ The image of point M = (4 + 3 , -3 - 5)

∴ The image of point M = (7 , -8)

The image of M is (7 , -8)
