Step-by-step explanation:
f(4)=-4+2=-2
The number would be 21 because if you add 5+37 then divide by 2.Younwill get the answer
Write the equation of the lines in slope-intercept form (y=mx+b)
First equation: It is already in slope-intercept form

Second equation: solve y:

Identify the slope of each line:
If two or more lines have the same slope then the lines are parallel
If two lines have slopes that are negative reciprocals then the lines are perpendicular
The two given lines have the same slope: 2/5. Then, they are parallel lines
