Answer:
21/8*2= 5 2/8 or 5 1/4
Step-by-step explanation:
Divide fraction so keep change flip
make them improper
21/8 * 2
42/8
5 2/8
5 1/4
Answer:
formula: a squared + b squared= c squared
6 squared+ 8 squared= c squared
36+64= c squared
100= c squared
Square root both sides
You get 10= c
First set up the equation 12x-7=4x+9
Get all the x's on one side and number on one side so you have 8x= 16
You get X=2
So for example B(4,1) so x=4, y=1
->B'(4-2,1-4)
->B'(2,-3)
->A'(1-2,1-4)
->A'(-1,-3)
->C'(4-1,-2-4)
->C'(3,-6)
->D'(1-2,-2-4)
->D'(-1,-6)
so the image of the rectangle ABCD->A'B'C'D'
Y-2x=6 => y=6+2x
Y+2x=0
(6+2x) + 2x = 0
6 + 4x = 0
4x= 6
X=6/4
X= 3/2
Y=6+2x
Y=6+2. 3/2
Y= 6 + 3
Y=9
Check: y-2x=6
9-2. 3/2 = 6
9 - 3 = 6
