  1. -5 is always smaller than -4. So, x might be -4. So, A is an option you should select.
  2. 2 is greater than -4. So, x might be -4. So, B is an option you should select.
  3. If we place -4 in x, we get 3(-4)+4, i.e., -12 + 4 = -8. So, 3x + 4 = -8. Therefore, you cannot select C because it cannot be greater than, it should be always equal to.
  4. 5(-4) = -20, 2(-4) - 3 = -8 -3 = -11. -11 is greater than -20 but they are never equal. So, you cannot select D.
  5. 4 - 2(-4) = 4 + 8 = 12. 12 is greater than -6. Therefore, you should select E.

<u>Answer</u>

<u>A,</u><u> </u><u>B,</u><u> </u><u>E.</u>

Hope you could get an idea from here.

If f(x)=7x+4x and g(x) =1/2x what is the value of (f/g)(5)
Aliun [14]

Answer:

(f/g)(5) = 22

Step-by-step explanation:

All we need to do is plug in 5 for x in both f(x) and g(x) then divide the result of f(x) and g(x) to find our final answer.

Step 1: Plug in 5 for x

f(x) = 7(5) + 4(5) = 55

g(x) = 1/2(5) = 2.5

Step 2: Divide f(x) by g(x)

f(5)/g(5) = 55/2.5 = 22

And we have our final answer!

A cross section is made by the intersection of a plane and a square pyramid at an angle either parallel or perpendicular to the
alukav5142 [94]
A cross section is the two dimensional shape that is created when a slice is made through a solid figure by an intersection of a plane and the solid body.

A square pyramid is a pyramid with a square base.

Case 1: When the plane intersects the square pyramid at an angle perpendicular to the base but not through the vertex. In this case a trapezoid is formed.

Case 2: When the plane intersects the square pyramid at an angle perpendicular to the base and through the vertex. In this case a triangle is formed.

Case 3: When the plane intersects the square pyramid at an angle parallel to the base. In this case a square is formed.

<span>Therefore, a cross section made by the intersection of a plane and a square pyramid at an angle either parallel or perpendicular to the base can be of shapes:

-square
-triangle
-trapezoid</span>
