Find each value f(-2) f(4) f(x)=-7.5 x=

Mathematics

Reptile [31]1 year ago

For the function f(x) = - 7.5 x, we get the values of f(-2) and f(4) as 15 and - 30 respectively.

Function:

A  function from a set X to a set Y assigns to each element of X exactly one element of Y.

We are given the function as:

f(x) = - 7.5 x.

We need to find the value of f(-2) and f(4).

The value of f(-2) will be:

Put x = -2:

f(x = -2) = - 7.5 (-2).

f(-2) = 15.

The value of f(4) will be:

Put x = 4:

f(x = 4) = - 7.5 (4).

f(4) = - 30.

Therefore, for the function f(x) = - 7.5 x, we get the values of f(-2) and f(4) as 15 and - 30 respectively.

I cannot find the answer to this can someone please help me

Answer:

A = 1,144 ft²

Step-by-step explanation:

The base of the quadrilateral is also x.  We know this since there are 2 90° angles, there fore the other 2 angles are also 90°, making the top and bottom sides of the quadrilateral parallel to each other, and equal in measure.  

Since the entire base of the yard is 2x, the base of the triangle is x.  

The area of the triangle is

A = (1/2)bh      where b is the base, and h is the height

For this example...

A = (1/2)x(44)                  (x is the base, and 44 is the height)

So

A = (1/2)(44)x

   A = 22x

The area of the quadrilateral is

A = LW    

A = 44x

The total area of the yard is

A = 22x + 44x

  A = 66x

We are told that the entire area is 3,462. so

3,462 = 66x           now solve for 'x'

3,462/66 = x           (divide both sides by 66)

52 = x        

So the area of the picnic tables is the area of the triangle, which is

A = 22(52) = 1,144 ft²
