If the traslation is T(x,y)=(x-1,y+1) then:

$T(-6,2)=(-6-1,2+1)=(-7,3)$

Therefore A'=( -7,3).

Question is in attached picture below

valina [46]

Answer:

My answer may not be accurate, but try (-4, 2)

I recommend using Khan Academy if you still don't understand the concept. (no shame btw)

Step-by-step explanation:

Here is a thorough explanation.

Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set {x | −3≤x≤1} . To write this interval in interval notation, we use closed brackets [ ]: [−3,1]

Could somebody please help me find the answers for 'x' for these pictures?

lesya692 [45]

Answer:

Pic 1: $x=31$

Pic 2: $x=20$

Step-by-step explanation:

<u>Picture 1:</u>

<u /> $2x+x-3=90\\3x-3=90\\3x=93\\x=31$

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

<u>Picture 2:</u>

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Factor both quadratic expressions. (x 4 + 5x 2 - 36)(2x 2 + 9x - 5) = 0

Sonbull [250]

So focusing on x^4 + 5x^2 - 36, we will be completing the square. Firstly, what two terms have a product of -36x^4 and a sum of 5x^2? That would be 9x^2 and -4x^2. Replace 5x^2 with 9x^2 - 4x^2: $x^4+9x^2-4x^2-36$

Next, factor x^4 + 9x^2 and -4x^2 - 36 separately. Make sure that they have the same quantity inside of the parentheses: $x^2(x^2+9)-4(x^2+9)$

Now you can rewrite this as $(x^2-4)(x^2+9)$ , however this is not completely factored. With (x^2 - 4), we are using the difference of squares, which is $a^2-b^2=(a+b)(a-b)$ . Applying that here, we have $(x+2)(x-2)(x^2+9)$ . x^4 + 5x^2 - 36 is completely factored.

Next, focusing now on 2x^2 + 9x - 5, we will also be completing the square. What two terms have a product of -10x^2 and a sum of 9x? That would be 10x and -x. Replace 9x with 10x - x: $2x^2+10x-x-5$
