55, 50, 45, 40, 35,…
  - 5  - 5  - 5  - 5

The common difference between the terms of the arithmetic sequence is -5, making the answer D.

a(n) = a₁ + d(n - 1)
a(n) = 55 - 5(n - 1)
a(n) = 55 - 5(n) + 5(1)
a(n) = 55 - 5n + 5
a(n) = -5n + 55 + 5
a(n) = -5n + 60

Polygon ABCD will be dilated by a scale factor of 2.2 with the origin as the center of dilation, resulting in the image A'B'C'D'
ikadub [295]
The answer is A. <span>m = undefined, C'D' = 13.2 units. When you dilate both C and D with the scale factor 2.2 with the origin as the center of dilation, their coordinates respectively become the following:
C' (22, 13.2) and D (22,26.4)

The difference between 26.4 and 13.2 is 13.2. The slope is undefined since it is s vertical line.

Which expression uses the associative property to make it easier to evaluate? (50points)
Naily [24]

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

Step-by-step explanation:

Given expression is:

8.(\frac{1}{4}.\frac{3}{5})

The associative property states that for any three terms that are being multiplied, different order of multiplication (i.e. which two terms are multiplied first) will give the same answer.

Let a,b and c be the three terms

then

a.(b.c) = (a.b).c

So applying the associative property on given expression

8.(\frac{1}{4}.\frac{3}{5}) = (8.\frac{1}{4}).\frac{3}{5}

Hence,

The correct answer is option 4: (8.\frac{1}{4}).\frac{3}{5}

What is the common difference in the following arithmetic sequence?7,3,-1,-5
Natasha2012 [34]

Answer:

-4

Step-by-step explanation:

The common difference is found by subtracting the second term from a previous term

So...

3-7 would give the common difference = -4

-1-3 would give the common difference= -4

-5-1 would give the common difference= -4
