<h3>FALSE</h3>
if r < 0, then is alternating
if 0 < r < 1, then is decreases
if r = 1, then is constant
if r > 1, then is icreases
The greatest common factor 27+36=63 is 9 times 7
Ratio 1:2:3 means we have x, 2x and 3x as the three parts
x+2x+3x = 42
6x = 42
6x/6 = 42/6
x = 7
Since x = 7, this means 2x = 2*7 = 14 and 3x = 3*7 = 21
Dividing 42 into the ratio of 1:2:3 means we have 7:14:21 as the answer
If we divide all three parts of 7:14:21 by the GCF 7, we reduce it down to 1:2:3
As a check,
7+14+21 = 21+21 = 42
so it works out
Answer:
3rd option
Step-by-step explanation:
Since the centre of dilatation is at the origin then multiply the coordinates by 
K (- 3, 9 ) → K' (- 3( ), 9( ) ) → K' (- 1, 3 )
L (- 9, 0 ) → L' (- 9( ), 0 ( ) ) → L' (- 3, 0 )
M (2, - 8 ) → M' (2 ( ), - 8 ( ) ) → M' ( 
, - 
)
N (6, 4 ) → N' (6 ( ) , 4 ( ) ) → N' ( 2, 
)
<h3>Question:</h3>
2x-5y=-28 find the value of y when x equals -19
<h3>Answer:</h3>
Y = - 2
<h3>Step-by-step explanation:</h3>
First you plug in -19 where x is 2(-19)-5y = -28
Remove parentheses -2 · 19-5y= -28
Multiply -2 by 19 -38-5y= -28
Add 38 to both sides -5y = 10
Divide both sides by -5 [tex]\frac{-5y}{-5} =\frac{10}{-5}[/tex
you will get -2 which is the answer.
Hope this helped!
