If three times a number plus four is no more than four times the number minus one, which of the
following are true? Let z represent the number
z>5
225
z 55
The number is at least 5.
The number is at most 5.

y= -

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

$452.90 because you needed to round to the nearest cent
