Answer:

f⁻¹(x) = 1/2 x + 2

Step-by-step explanation:

f(x) = 2x - 4      y=2x - 4

swap x and y:  x = 2y - 4

solve y:   2y = x + 4

y = 1/2 x + 2

Inverse notation:   f⁻¹(x) = 1/2 x + 2

Answer: [tex]6ft < x < 30ft[/tex]

6ft is less then x and x is less then 30ft

Step-by-step explanation:

The possible length of the third side is 7 < x < 29.

Polygon which has three sides and three vertices are called a triangle.

The sum of all the angles of the triangle is 180°.

Given:

The lengths of the other two sides of a triangle are 11 feet and 18 feet.

Let the third side's length is x feet.

The sum of the two sides of the triangle is always greater than the length of the third side of the triangle.

That means,

18 + 11 > x.

And 11 + x > 18.

So, we have a possible choice,

11 + 18 < x

Simplifying,

29 < x.

Arranging in better terms,

x > 29.

Another possible choice,

18 -11 < x

7 < x

Combining both inequalities,

we get,

7 < x < 29.

Therefore, 7 < x < 29.

Answer:

the second one

Step-by-step explanation:

The table that represents a linear function is the first one, where the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.

The first table:

x: 1,2,3,4,5

y: 5,20,45,80,125

In this table, the values of y are obtained by multiplying the corresponding values of x by a constant factor of 5.

The relationship between x and y is consistent and can be expressed by the equation y = 5x, which is a linear function.

The second table:

x: 1,2,3,4,5

y: 5,25,125,625,3125

In this table, the values of y are obtained by raising the corresponding values of x to increasing powers of 5.

The relationship between x and y is not consistent and cannot be expressed by a linear function.

Answer:

f = 132 degrees

Step-by-step explanation:

The total angle measure of this is 360 degrees. We know 2 of the angles, so subtract them from 360 to get 198. The sum of f and g must equal 198 degrees. Since we know that f = 2g, we can divide 198 by 3 to get 66. So, we know g = 66. To find f, multiply 66 by two to get 132. So, g = 66 and f = 132

Answer:

110 degrees

Step-by-step explanation:

The sum of all the interior angles of a polygon is always equal to 180(n-2) where n is the number of sides. In this figure, there are 7 sides. This means that the sum of all the interior angles is 180(7-2) = 180 * 5 = 900.

Now, add up all the angles that you know and subtract that from 900 to find the value of x.

900 - (105 + 150 + 140 + 135 + 125 + 135) = 900 - 790 = 110 degrees

Answer:

Step-by-step explanation:

Solution,

Here,

A=(6,3) (x1,x2)

B=(8,-8) (y1,y2)

AB=?

Now,

(AB)^2=(x2-x1)^2+(y2-y1)^2

Now putting the value of x1,x2,y1,y2

=(3-6)^2+(-8+8)^2

= (-2)^2+(0)^2

= (-4,0)

AB=(-4,0)
