a carpenter cuts the corners of a rectangle to make the trapezoid shown. what is the value of x? 5.375 5.5 11 13

Step-by-step explanation: Not completely sure but i think the answer is 11

11

Step-by-step explanation:

A trapezoid is quadrilateral where 2 sides are non parallel and the other two sides are parallel.

An Isosceles Trapezoid consists of non parallel sides having the same angle between the base and top. Here we do not know the other two angles so we have applied the following theorem:

In a trapezoid the sum of the angles on the same side is equal to 180°

So,

9x+7x+4 = 180

⇒16x+4 = 180

⇒16x = 180-4

⇒16x = 176

⇒x = 176/16

⇒x = 11

∴ The value of x is 11

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
