The rectangular prism is to be sliced perpendicular to the shaded face and is to pass through point B ,parallel to the front face. What will the dimensions of the rectangular cross section be?

A. 8 centimeters by 18 centimeters

B.8 centimeters by 10 centimeters

C.10 centimeters by 18 centimeters

D. 4 centimeters by 18 centimeters

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

answer is  

a.

p = 78

the answer on ed. is:

c. "the graph of f(x) has exactly two x-intercepts."

hope i could someone! : )
