Answer:
there is none
Step-by-step explanation:
Answer:x=53/6 and y=-55/6
Step-by-step explanation:
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6
Answer:
832,000
Step-by-step explanation:
Answer:
x>6
Step-by-step explanation:
-3x<-18
3x>18
Therefore, x>6
There are many ways to do this. Such ways are using the quadratic formula, completing the square, etc.
We have
We can add 46 to both sides so the -21 becomes a +25. by doing that, we get
This can be wrote as
We solve the square root and get
(The +- is a plus minus sign.) Subtract five on both sides to get
The answer is
C.
