A length of ribbon is cut into two pieces to use in a craft project. The graph shows the length of the second piece, x, for each

djyliett [7]

Answer:

Part A) The length of the ribbon is 15 feet

Part B) $m=-1$

Part C) see the explanation

Step-by-step explanation:

Part A)

Let

x -----> the length of the second piece of ribbon in feet

y -----> the length of the first piece of ribbon in feet

we know that

The length of the ribbon is equal to the sum of the first piece and the second piece of ribbon

y+x

take any point from the graph

Example

(13,2)

That means

Second piece ----> x=13 ft

First piece ----> y=2 ft

The length is (y+x)=2+13=15 ft

Part B) What is the slope of the line?

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

take the intercepts from the graph to calculate the slope

we have

(0,15) and (15,0)

substitute

$m=\frac{0-15}{15-0}$

$m=-1$

Part C) Explain what the slope of the line represents

we know that

The slope is equal to -1

That means, that we have a decreasing function, as the value of x (length of second piece) increases by one, the value of y (length of the first piece) decreases by one

The slope fits in the story because the linear equation in slope intercept form between the variable x and the variable y is equal to

$y=-x+15$

Classify the four angles of the quadrilateral. B 105° A .90° 75° C 90° D LA LB 4C ZD Right Acute Obtuse O X O O Ś ?

earnstyle [38]

The picture has a quadrilateral with ABCD angles.

∠A=90° is right angle

∠B=105° is obtuse angle

∠C=75° is acute angle

∠D=90° is right angle

Given that,

The picture has a quadrilateral with ABCD angles.

The angle are

∠A=90°

∠B=105°

∠C=75°

∠D=90°

We have to clarify the angles of the quadrilateral.

∠A is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.

∠B is obtuse angle because a form of angle known as an obtuse angle is one that is always greater than 90° but less than 180°.

∠C is acute angle because an acute angle is one that is smaller than 90 degrees in length. L-shape shapes at 90°

∠D is right angle because the right angle is created when two straight lines cross at a 90° angle or when they are perpendicular at the intersection.
