Answer:
<em>(3). 500; (4) 60</em>
Step-by-step explanation:
Equation- 8x(12+7-9)-(4+10)
Answer- 80x−14
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:

Answer:

The value of X is 35 because the angle 35 measures the same as the angle X, hence their values are the same
4,165 because you have to subtract the 4200 and 35 because when you read the word problem it says difference which means subtract
