A reflection about the x axis, about y=0, is the mapping (x',y')=(x,-y) so
A dilation of 2 is the mapping (x'',y'')=(2x', 2y')
So
We can rewrite that without the primes and combine the powers of 2.
Let's graph these and see if we're close,
Plot y= (1/4)^x, y= - (1/4)^{x}, y = - 2^{1-x}
The rectangle i would say is a parallelogram. Since a parallelogram has sides that are parallel which explains the name: parallelogram :) :D
Answer:
y=2x-2
Step-by-step explanation:
Slope intercept form y= mx+b
y-4 = 2(x-3)
y-4= 2x-6
y-4+4= 2x-6+4
y= 2x-2
129,407 because 12 ten thousands is 120,000 and 8 thousands is 8,000. 14 hundreds is 1,400 and 7 ones is 7 so 120,000+8,000+1,400+7=129,407
72 hours is exactly 3 days...
