Answer:

I believe it's a parallelogram.

Step-by-step explanation:

So a parallelogram has opposite sides congruent which when plotting the points opposite sides are the same length which makes it a parallelogram. In addition the opposite sides are parallel also which also justifies how the shape is a parallelogram.

The quadrilateral is a parallelogram because it has two pairs of parallel sides and the opposite sides are equal.

Identify each sequence as arithmetic or geometric. Explain your answer, and write an explicit formula for the

hammer [34]

Answer:

Arithmetic sequence

$a_n=\frac{1}{2}-n$ for $n\geq 1$

Step-by-step explanation:

We are given that a sequence

$-\frac{1}{2},-\frac{3}{2},-\frac{5}{2},-\frac{7}{2},...$

We have to identify the sequence as arithmetic or geometric and write an explicit formula .

$a_1=-\frac{1}{2}$

$a_2=-\frac{3}{2}$

$a_3=-\frac{5}{2}$

$a_4=-\frac{7}{2}$

$d_1=a_2-a_1=\frac{-3}{2}+\frac{1}{2}=-1$

$d_2=a_3-a_2=-\frac{5}{2}+\frac{3}{2}=-1$

$d_1=d_2=-1$

When the difference of consecutive terms is constant then the sequence is an arithmetic.

Hence, the sequence is an arithmetic.

$a_n=a+(n-1)d$

$a_n=-\frac{1}{2}+(n-1)(-1)=-\frac{1}{2}-n+1=\frac{1}{2}-n$ for $n\geq 1$

Solve for x<br>3x² - 5x + 6 = 10 - 4x

Nutka1998 [239]

Answer: $-1, \frac{4}{3}$

Step-by-step explanation:

$3x^{2}-5x+6=10-4x\\\\3x^{2}-x-4=0\\ \\ (x+1)(3x-4)=0 \\ \\ x=\boxed{-1, \frac{4}{3}}$

Answer:

1. $6000

2. 40.9%

3. 51.6%

4. Misc

Explained :

1. 1800 + 150 + 2450 + 1300 + 300 = 6000

2. 2450/6000 = 0.409 = 40.9%

3. 1800 + 1300 = 3100 ; 3100/6000 = 0.516 = 51.6%

4. 300/6000 = 0.005 = 5%
