Given:

The function is:

[tex]f(x)=-2x+5[/tex]

To find:

The inverse of the given function, then draw the graphs of function and its inverse.

Solution:

We have,

[tex]f(x)=-2x+5[/tex]

Step 1: Substitute [tex]f(x)=y[/tex] .

[tex]y=-2x+5[/tex]

Step 2: Interchange x and y.

[tex]x=-2y+5[/tex]

Step 3: Isolate variable y.

[tex]2y=5-x[/tex]

[tex]y=\dfrac{5-x}{2}[/tex]

Step 4: Substitute [tex]y=g(x)[/tex].

[tex]g(x)=\dfrac{5-x}{2}[/tex]

Hence, the inverse of the given function is [tex]g(x)=\dfrac{5-x}{2}[/tex] and the graphs of these functions are shown below.

Answer:

  7) 57.8

  8) 73.8

Step-by-step explanation:

The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.

7) P = 2(22.2 +6.7) = 57.8

8) P = 2(22.9 +14) = 73.8

Answer:

(a) x=45°

(b) If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.

Step-by-step explanation:

(a)

Angles in a quadrilateral add to 360:

<A+<B+<C+<D=360

2x+90+x+3x=360

6x=270

x=45°

(b)

If AD was parallel to BC, <A would be equal to (180-<B)=90 (corresponding angles). Since <A≠90, we can see that AD and BC aren't parallel.

Answer:  Step-by-step explanation:

3x+2x+x=360-90

6x=270

x=45

∠DAB=2x=90° and ∠ABC=90° ⇒ AD║BC

What is the area, in square inches, of the isosceles trapezoid below?

Answers

A = 73.84

Explanation-

14.2 - 6.4 = 7.8 (to get the length of the base without the top part)

7.8 • 5.2 = 40.56 (to find the area outside of our subtracted square that has the top part)

6.4 • 5.2 = 33.28 (to find the area of the inner square)

40.56 + 33.28 = 73.84 (adding together both parts to find the total area)

A = 73.84
