Which of the following equations represents a line that is parallel to the line with the equation y = 2/3x +2

Andreyy89

Answer: C. 4x - 6y = 3

Step-by-step explanation:

We only need to find a line with the same slope.

We will put 4x - 6y = 3 in slope intercept

4x - 6y = 3

-6y = -4x + 3

y = 4/6 - 3/6

y = 2/3 - 1/2

There you have it, a line with the same slope, which means it's parallel.

Find the sum of 46 + 42 +38... +(-446) +(-450)

schepotkina [342]

The sum of the given sequence is -24846.

Step-by-step explanation:

The given Arithmetic sequence is 46 + 42 +38... +(-446) +(-450).

The first term of the sequence = 46
The last term of the sequence = -450
The common difference ⇒ 46 - 42 = 4

To find the number of terms in the sequence :

The formula used is $n = (\frac{a_{n}-a_{1}} {d})+1$

where,

n is the number of terms.
$a_{n}$ is the late term which is -450.
$a_{1}$ is the first term which is 46.
d is the common difference which is 4.

Therefore, $n =(\frac{-450-46}{4}) +1$

⇒ $n = (\frac{-496}{4}) + 1$

⇒ $n = -124 + 1$

⇒ $n = -123$

⇒ n = 123, since n cannot be negative.

∴ The number of terms, n = 123.

To find the sum of the arithmetic progression :

The formula used is $S = \frac{n}{2}(a_{1} + a_{n} )$

where,

S is the sum of the sequence.
$a_{1}$ is the first term which is 46.
$a_{n}$ is the late term which is -450.

Therefore, $S = \frac{123}{2}(46+ (-450))$

⇒ $S = \frac{123}{2}(-404)$

⇒ $S = 123 \times -202$

⇒ $S = -24846$

∴ The sum of the given sequence is -24846.

How to convert 11 to base 10

blondinia [14]

The given number which is 2A193A411 is written in Base 11. Base 11 number is also called undecimal system. The digits of Base 11 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10. Since 10 is not accepted as a digit, then we have to substitute a variable which is A = 10. Hence, the digits of a Base 11 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and A.
