To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.
In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2
Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.
Answer choice C is the best option.
I hope this helps! :)
In the future, would you please post just one or two problems at a time. Be fair to others who also want help.
#5: <span>(-4)^8/(-4)^4 can be expressed more clearly as (-4)^8
---------
(-4^4)
and this can be reduced to (-4)^4 by subtracting the exponent 4 from the
exponent 8.
furthermore, because of the even exponent, (-4)^4 can be written as 4^4.
Note that 4^4 = (4^2)^2 = 16^2 = 256 (answer)</span>
I believe the answer is c
Try them
remember, (x,y)
so
(1,0)
if x=1 and y=0
y>-3x+4
0>-3(1)+4
0>-3+4
0>1
false, nope, not (1,0)
(-1,1)
x=-1 and y=1
y>-3x+4
1>-3(-1)+4
1>3+4
1>7
false, not (-1,1)
(2,2)
x=2, y=2
y>-3x+4
2>-3(2)+4
2>-6+4
2>-2
true
try the other
y≤2x-2
2≤2(2)-2
2≤4-2
2≤2
true
this is the answer
