Which statement describes the graph of f(x) = 4x7 + 40x6 + 100x5? The graph crosses the x-axis at x = 0 and touches the x-axis at x = 5.
The graph touches the x-axis at x = 0 and crosses the x-axis at x = 5.
The graph crosses the x-axis at x = 0 and touches the x-axis at x = –5.
The graph touches the x-axis at x = 0 and crosses the x-axis at x = –5.

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,

step-by-step explanation:

replace   with   27   and simplify.

10 , 27 , 10 , 70 , 10 , 35 , 10 , 48

step-by-step explanation:

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
