Answer: See the description below.

The residuals are the difference between the actual and predicted values. Just subtract those values and plot the point.

Your points will be:

(2, 0)
(3, 4)
(4, -5)
(6, -1)
(7, 2)

Jordan is cutting a 2 meter by 1 1/4 meter into two pieces by its diagonal line
Airida [17]

Question:

Jordan is cutting a 2 meter by 1\frac{1}{4} meter piece of rectangular paper into two pieces along its diagonal. what is the area of each of the pieces?

Answer:

Area of each piece of paper is 1 \frac{1}{4} \ m^2.

Solution:

Length of the paper = 2 m

Width of the paper =  1\frac{1}{4} m =  \frac{5}{4} m

<em>Area of the rectangle = length × width</em>

                                    $=2\times \frac{5}{4}

                                    $= \frac{5}{2} \ m^2

<em>Diagonal of a rectangle divides it into two equal parts.</em>

Area of each piece = Area of the rectangle ÷ 2

                                $=\frac{ \frac{5}{2}}{2}

                                $=\frac{5}{4} \ m^2

                                $=1 \frac{1}{4} \ m^2

Area of each piece of paper is 1 \frac{1}{4} \ m^2.

Can someone help me answer these two questions
andrew11 [14]

Answer:

C) 7=y=5x+11

B) m=-4/5, b=13/5

Step-by-step explanation:

<u>Problem 1:</u>

A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.

<u>Problem 2:</u>

Convert to slope-intercept form (y=mx+b):

4x+5y=13

5y=13-4x

y=13/5-4/5x

y=-4/5x+13/5

Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.

</span>The distance poles B and E= BD+DE=4/5+7/10=(8+7)/10=15/10=3/2 yard

the answer is 3/2 yard (distance poles B and E)
