2 n - 5 = 3
So A is the answer
Answer:
√7i = x
Step-by-step explanation:
x²+y²=9;
y² = 9-x²
y = √(9-x²)
As line is given by y= 4, the solution of the system is:
4 = √(9-x²)
16 = 9-x²
7 = -x²
-7 = x²
√-7 = x
As √-7 doen't exist, you should use i = √-1;
Thus,
<em>√7i = x</em>
<em></em>
I hope it helps!
Answer:
it has no solutions
Step-by-step explanation:
y = mx + b
y = -5x - 1......slope here is -5 and y int is -1
y = -5x + 7....slope here is -5 and y int is 7
Twenty-five hundreths times a number plus six tenths times a number.
