Answer:

y = (-1/5)x + 1

Step-by-step explanation:

The slope of this perpendicular line is the negative reciprocal of the slope of the given line y = 5x + 4: -1/5.

Applying the slope-intercept form of the equation of a line, we get:

2 = (-1/5)(-5) + b, or:

2 = 1 + b

Therefore, b = 1 and the desired equation is:

y = (-1/5)x + 1

tigry1 [53]

Answer:

$4x^3 < 40 - x$

Explanation:

let the number be x, now we are given that four times the cube of a number which means four multiplied by the cube of number

i.e 4 multiplied by $x^3$ is less than the difference of 40 and the number x i.e 40 - x

x is for sure less than 40 as $x^3$ is less than the difference between 40 and x so if we write x - 40 then we will obtain negative value which will be greater than $x^3$ .

So, the inequality obtained can be written as $4x^3 < 40 - x$
