Step-by-step explanation:
= -√1
= -1
= √1
= 1
Difference -√1 and √1 are the sign of the number, where -√1 is negative and √1 is positive
Answer:
x = 7 , y= - 6
Step-by-step explanation:
4x = -2 - 5y ___(1)
4x= 10 - 3y ___(2)
so, now by simultaneous equations,
10 - 3y = - 2 - 5y
2y = -12
y = -6
if y = -6
then, 4x= 10 -3(-6)
4x =28
x = 7
Answer:
It is A [1st option]
Step-by-step explanation:
Use process of elimination.
The last 2 would not work since 3^0 is 1 not 0.
Then you can eliminate the 2nd option as it says 2^3^2 is 2^5 which is wrong... it would be 2^6
Therefore, it is A
As they are written, they are all linear. I think you meant for the third one to be y=x^2. if that is true then y=x^2 is a quadratic and therefore is the answer
