A linear equation exists for the following sets of ordered pairs: {(-1, 1), (0, 3), (-1/3, 7/3)}. The rule for the linear equati
kaheart [24]

Answer:

Part 1) y=2x+3

Part 2) The equation satisfy the set of coordinates (see the explanation)

Step-by-step explanation:

step 1

Find the linear equation

The rule for the linear equation states that y is three more than twice x.

so

The variable y is equal to the number 2 multiplied by x plus the number 3

y=2x+3

step 2

Prove that the equation satisfies the set of coordinates

substitute the value of x and the value of y in the linear equation and then compare the results

a) (-1, 1)

1=2(-1)+3

1=1 ----> is true

so

The equation satisfy the ordered pair

b) (0, 3)

3=2(0)+3

3=3 ----> is true

so

The equation satisfy the ordered pair

c) (-1/3,7/3)

7/3=2(-1/3)+3

7/3=7/3 ----> is true

so

The equation satisfy the ordered pair

therefore

The equation satisfy the set of coordinates

A car is traveling at a speed of 72 kilometers per hour. What is the car's speed in kilometers per minute? How many kilometers w
Kryger [21]

Answer:

1.2 kilometers per minute; 6 kilometers in 5 minutes

Step-by-step explanation:

To find the KM per minute, divide the speed per hour (72) by 60 (minutes in one hour)

72/60 = 1.2 KM per minute

To find the KM for 5 minutes, multiply the KM per minute (1.2) times 5 minutes: 1.2*5 = 6 KM

Shawna, Dexter, and Tilana are solving the equation Negative 2. 5 (5 minus n) 2 = 15. Shawna says, "I can begin by dividing each
aleksandrvk [35]

Shawana, Dexter, and Tilana are correct.

<h2>Given that</h2>

Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;

<h3>We have to determine</h3>

Which students are correct?

<h3>According to the question</h3><h3>Equation: \rm  -2.5(5 - n) + 2 = 15&#10;&#10;&#10;</h3>

The correct way to solve the equation is;

SHAWNA

Statement: Dividing each side of the equation by –2.5,

\rm  \dfrac{-2.5(5 - n) + 2 }{-2.5}= \dfrac{15}{-2.5}\\&#10;\\&#10;(5-n) - \dfrac{2}{2.5} =  \dfrac{15}{-2.5}\\\\&#10;\\&#10;

Here, Shawna is correct.

DEXTER

Statement: Distributing -2.5 to get -12.5 + 2.5 n + 2 = 15.

\rm -2.5(5-n) +2=15\\&#10;\\&#10;-2.5(5) - 2.5 (-n) +2= 15\\&#10;\\&#10;-12.5 +2.5n +2=15

Hence, Dexter is correct.

" Tirana says, "I can begin by multiplying each side of the equation by Negative Start fraction 1 over 2. 5 End fraction to get 5 minus n minus 0. 8 = negative 6. "

\rm \dfrac{-1}{2.5} (-2.5 (5-n)+2)= \dfrac{-1}{2.5}\times 15\\&#10;\\&#10;(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\&#10;\\&#10;(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\&#10;\\&#10;5-n-0.8=-6

Hence, Tilana is also correct.

Hence, Shawana, Dexter and Tilana are correct.
