Your answer is x² + 2x + 1
Answer:
y = 36
Step-by-step explanation:
Everything in x-column is multiplied by 2, so everything in y-column is divided by 2 as per the inverse function.
=> 72/2
=> 36
Answer:
The three-digit numbers with these properties are 850 or 941.
Step-by-step explanation:
Let x be the hundreds digit, y the tens digit, and z the ones digit. The first condition says that 
. The second condition is:
the original number is 
while the reversed number is 
so
Now we have the system
You can divide by 99 to simplify the second equation.
Note that x, y, z must be digits between 0 and 9 and 
. If 
, then the second equation forces 
, for example z=2 so x-2=8, x=10 which is impossible. If z=0, you get x=8, y=5 and the number is 850. If z=1, you get x=9,y=4 and the number is 941.
Answer:
B. 2/3
Step-by-step explanation:
0 is less than 1 but not greater than 0.
1 isn't less than 1 but is greater than 0.
3/2 is actually 1.5. 1.5 isn't less than 1 but is greater than 0.
The correct answer is 2/3 because:
2/3 is less than 1 whole.
2/3 is greater than 0.
Hope this helps.
