Answer:
+5 or -5.
Step-by-step explanation:
Given equation,
5x-10/x^2-25
When you divide something with zero, it becomes undefined. So, to be undefined, x will have to be that value which makes the divisor zero.
Now, x^2-25= 0
Or, x^2= 25
Or, x= +5,-5.
So, for the value +5 and -5, the divisor becomes zero and makes the whole equation undefined.
Answer: C - 4 = 14
Step-by-step explanation: In the expression, "c"<em> </em>is colin's age so, if you subtract 4 years for his age, you get Katie's age, which is 14.
Answer:
Step-by-step explanation:
As two sides are equal so angles opposite to these are also equal, hence
5x-4=x+52
4x=56
X=14
Now,
R=5x-4
R=66
And,Q=x+52
Q=66(we already knew both angles are equal)
Now as sum of all angles of triangle equal 180 so,
66+66+P=180
P=48
A histogram would work best here because in this scenario there is not enough info for a dot plot
Answer:
Is a consistent independent system
Step-by-step explanation:
we know that
If a system has at least one solution, it is said to be consistent .
If a consistent system has exactly one solution, it is independent .
If a consistent system has an infinite number of solutions, it is dependent
If a system not have solution, it is said to be inconsistent
In this problem we have
----> equation A
----> equation B
Solve the system by graphing
The solution is the intersection point both graphs
The solution is the point (7.5,-20.5)
see the attached figure
therefore
Is a consistent independent system
