A=(2,4); B=(3,9); C=(4,1)
A'=(4,-2); B'=(9,-3); C'=(1,-4)

All the points P=(x,y) change to P'=(y,-x), this corresponds to a rotation counterclockwise about the origin, then:

-2x+2y=6 7x-8y=-27 what is the solution

navik [9.2K]

-2x+2y=6
7x-8y=-27
5x-6y=-21
-x+y=3
6x-7y=-24
6x-7y=-4(-2x+2y)
6x-7y=8x-8y
-6x from both sides:
-7y=2x-8y
add 8y to both sides:
y=2x
-2x+2y=6
2y-6=2x
2y-6=-12
-6-6=-12
y=-3
x=-6

Hope this helps :)

Answer:

$22,360

Step-by-step explanation:

Whenever you have a percentage increase, multiply the original value with the percent in decimal form plus one. For example, $21,500 increased by 4% is the equivalent to 21,500 * 1.04. If it decreased by 8%, you would do 21,500 / 1.08.

A sample of n = 4 scores is selected from a population with m = 40 with s = 8, and the sample mean is M = 43. What is the standa

vladimir2022 [97]

Standard error (SE)
$se= \frac{s}{ \sqrt{n} }$
Or

$se = \sqrt{ \frac{ {s}^{2} }{n} }$

Therefore, SE of the mean = (8)/(2) =4
