Answer:
106
Step-by-step explanation:
Given:
Thirteen fewer than three times his thinking number is 305.
Question asked:
What number is Tomás thinking ?
Solution:
Let Toma's thinking number be
As 13 fewer than 3 times his thinking number is 305.
The equation will be:
Adding both side by 13
Dividing both side by 3
Thus, Tomàs was thinking of a number is 106
Hey There!
The answer to your problem is or
both answers are correct!
<u>Step 1: Subtract x²+12 from both sides.</u>
−7x−(x²+12)=x²+12−(x²+12)
−x²−7x−12=0
<u>Step 2: Factor left side of equation.</u>
<u>Step 3: Set factors equal to 0.</u>

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:
We find the slope of the line:
Thus, the equation of the line is of the form:
We substitute one of the points and find b:
Finally, the equation is:
