If the intercepts of a line are (a,0) and (0,b), what is the slope of the line?

Generally gradient = (Y2-Y1)/(X2-x1)
from the above
y2= b
y1=0
x2=0
x1=a
so gradient= (b-0)/(0-a) = b/-a =-b/a

A line passes through the point (1,4) and is perpendicular to the line with equations y=-1/5x+2. what's the equation of the line
jekas [21]

To find the slope of the perpendicular line, you can take the negative reciprocal of the slope of the line it is perpendicular to.

Taking the negative reciprocal of -1/5 gives 5.

Now we have y=5x+b, where b is the y-intercept. Since we know that the perpendicular line passes through the point (1,4), we can substitute those values into the equation we have to find b.

y=5x+b

4=5(1)+b

4=5+b

b=-1

Therefore, the equation of the perpendicular line is y=5x-1.

The volume of a packing box is 5 – x cubic feet. The width of the box is x feet and the length is x – 2 feet. The height is give
photoshop1234 [79]
By definition we have that the volume is given by
 V = h * w * l
 where
 V: Volume
 h: height
 w: width
 l: length
 Clearing the height we have:
 h = V / (w * l)
 h = (5 - x) / ((x) * (x - 2))
 The expression is not defined for the values of x that make the denominator zero:
 ((x) * (x - 2)) = 0
 x = 0
 x = 2
 Answer
 h = (5 - x) / ((x) * (x - 2))
 x = 0
 x = 2
