Answer:
The graph has 1 x-intercept
Step-by-step explanation:
Given
Required
- Discriminant of f
- Number of x intercepts
Let D represent the discriminant;
D is calculated as thus
Where a, b and c are derived from the following general format;
By comparing with
We have
Solving further;
So, D can now be calculated;
becomes
Hence, the discriminant of f is 0
From the value of the discriminant, we can determine the number of x intercepts of the graph;
When D = 0, then; there exists only one x-intercept and it as calculated as thus
Recall that
So, becomes
5 times 6x =30x the second one is 7y+7x the third one is 8x+20y
The answer is 49=7x7 but it could be written as 49=7^2 too
