Factor completely. 81-100x^2

Mandarinka [93]

Answer:

(9-10x)(9+10x) (I think this is the answer but I'm not one hundred percent sure)

Step-by-step explanation:

First, you can recognize that both numbers (-100x^2 and 81) are a difference of squares, in which means that they both can be square routed. Then, plug in the square routes of the numbers into (9-10x)(9+10x). 9 is the square route of 81 and 10 is the square route of 100. Make sure that when you put the numbers in the parenthesis that there is one negative and positive number since a negative multiplied by a positive makes a negative, hence making 100 negative. I hope that helped.

Given the sets A = {-4, -1, 3, 5, 9} and B = {-2, -1, 0, 1, 2, 3}, the set AUB (u is upside down) is given by:

ki77a [65]

The upside down U is the symbol for the intersection of sets. The intersection of two sets is the set that contains the elements that are common to both sets. Which elements are both in set A and in set B?

Answer: {-1, 3}

What is the value of x? pls help ;-;

leonid [27]

Answer:

39 degrees

Step-by-step explanation:

A triangle sums up at 180 degrees.

Therefore, 102+39=141.

Subtract 180 by 141 and you get 39!

To know if your answer is correct, add all angles and

make sure to get 180 in total!

Determine the equation of the line passing through the points (-1, 1) and (1, 7).

evablogger [386]

Answer:

$3x + y = -4$

Step-by-step explanation:

We were given to points on the line we are trying to find, hence we are able to determine the slope/gradient.

$( - 1, \: 1) \: and \: (1, \: 7) \\ slope = \frac{ {y}^{2} - {y}^{1} }{ {x}^{2} - {x}^{1} } \\ \\ s = \frac{7 - 1}{1 - ( - 1)} \\ s = \frac{6}{2}$

Slope is equal to 3.

Since we have the value for the slope, we can now use one of the points on the line to determine the equation of the line.

note that the coefficient of x is the slope. In this case the A from the standard form (Ax + By= C) is the slope.

$\\ let \: us \: use \: the \: point \: ( - 1, \: 1) \\ a = 3 \: \: \: \: y = 1 \: \: \: x = - 1\\ ax + by = c \\ 3( - 1) + 1 = c \\ - 3 + 1 = c$

$- 2 = c \\ therefore \: the \: equation \: of \: the \\ \: line \: is \\ ax + by = c \\ 3x + y = - 4$
