b. The slope of the line is 15.
c. The slope of the line is -10.
d. The slope of the line is -15

Answer 1
Answer:

Answer:

a.the slope of the line is 1.5

Step-by-step explanation:

Hello

if two points of a line are known(P1 and P2), it is possible to find the slope of the line, the slope of a line is given by:

slope=(y_(2)-y_(1))/(x_(2)-x_(1)) \nm=(y_(2)-y_(1))/(x_(2)-x_(1))\n

P1=(x_(1) ,y_(1)) \nP2=(x_(2) ,y_(2))

Step 1

define

P1=(84,80) , x_(1)=84 ,y_(1)=80\nP2=(74,65) , x_(2)=74 ,y_(2)=65

Step 2

put the values into the equation

m=(y_(2)-y_(1))/(x_(2)-x_(1))\nm=(65-80 )/(74-84)\nm=(-15)/(-10)\n m=(15)/(10)=(3)/(2)=1.5

the slope=1.5

I hope it helps, have a great day

To convert from square miles to square feet,what operation will you use

Answers


The correct one is multiplication.

-- Take the number of square miles.

-- Multiply it by the fraction      (5,280 feet / 1 mile)² .

-- After canceling things where possible, simplifying, and
cleaning up the product, what you have is the same area
expressed in square feet.
Multiplication because to convert from a larger unit, miles, to a smaller unit, feet, you multiply the number of miles by the number of feet in a mile to get the total number of feet.

Find the slope of the line graphed below.

Answers

Answer:

The answer to your question is m = - (4)/(7)

Step-by-step explanation:

Process

1.- Find two points of the line (red points)

   A ( 4, -5)  and B (- 3 , -1)

2.- Find the slope using the formula

    m = (y2 - y1)/(x2 - x1)

  Substitution

   m = (-1 + 5)/(-3 - 4)

   m = - (4)/(7)

A real estate agent used the mean and MAD to argue that the home prices of Pepper Hill Road were higher and less variable than those of Cinnamon Court. What is the agent’s error?He should have used the median and IQR because the data is symmetric.

c. segment AD congruent segment BC
d. segment AC congruent segment BD

Answers

Answer:

A. Segment AB congruent segment CD

C. Segment AD congruent segment BC

Step-by-step explanation:

These are both true because a characteristic of a rhombus is that all four sides are congruent. Therefore we must prove that AB is congruent to CD and AD is congruent to BC.
