Check first one:
2(-2)- 3(1) < 1
-4 -3 < 1
-7 < 1
This is true, let's check others, just to be sure
Check second one:
2(1/2) - 3(0) < 1
1 - 0 < 1
This is false
Check third one :
2(2)- 3(1) < 1
4- 3 < 1
This is false
So answer is (-2,1)
Answer:
x=20.
Step-by-step explanation:
2x+8=48
48-8
2x=40
40/2
x=20 DVD's
First one is 24 because 4x6=24 and the second one is 35 because 7x5=35 if you need more help just let me know :)
So, this is -4 * 5 * -1 * -2
this is -20 * 2
total is -40
Hope this helps :)
Answer:
the second statement is not true
Step-by-step explanation:
If x squared equals 100, it doesn't mean necessarily that x is positive ten, since you can get 100 also by squaring the value (-10):
(-10)
The second statement is ignoring the possibility of x being a negative ten which also gives 100 as answered when squared.
