Solve the equation. Isolate the variable, x.

Note the equal sign, what you do to one side, you do to the other.

First, subtract 8 and 10x from both sides:

2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)

2x - 10x = 12 - 8

Simplify. Combine like terms:

(2x - 10x) = (12 - 8)

-8x = 4

Isolate the variable, x. Divide -8 from both sides:

(-8x)/-8 = (4)/-8

x = -(4/8)

Simplify:

x = -1/2

-1/2 is your answer for x.

How do you do this?? <br> explain it well please!

Group like terms together. We'll get 4x on the left side of our equation and 16 on the right side. Then 4x = 16, and x = 4 (answer)

The first term of an arithmetic sequence is -2. The eighth term of the sequence is 26. What is the common difference of the arit

andreev551 [17]

Answer:

d = 4

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given a₁ = - 2 and a₈ = 26 , then

- 2 + 7d = 26 ( add 2 to both sides (

7d = 28 ( divide both sides by 7 )

d = 4

A rectangle has the following vertices. Find the area of the rectangle. (9, −1), (−1, 7), (−5, 2), (5, −6)

stiks02 [169]

Answer: 82 sq. units .

Step-by-step explanation:

Let A (9, −1), B (−1, 7), C(−5, 2), D(5, −6) are the vertices of rectangle.

Then we plot them on graph ( as provided in attachment)

Length = AB $=\sqrt{(9+1)^2+(-1-7)^2}$ units [By distance formula : $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ ]

$=\sqrt{(10)^2+(-8)^2}=\sqrt{100+64}=\sqrt{164}=2\sqrt{41}$ units

Width = BC = $\sqrt{(-1+5)^2+(7-2)^2}$ units

$=\sqrt{4^2+5^2}\\\\=\sqrt{16+25}\\\\=\sqrt{41}$

Area = length x width

= $2\sqrt{41}\times\sqrt{41}=2\times41= 82\text{ sq. units}$

Hence, the area of the rectangle is 82 sq. units .
