Answer:

$ 117.36

Step-by-step explanation:

On the drawing, the rectangular room measures 3 inches by 2 inches, we can convert to feet (using a scale of Inch - 2 feet )

(3 inches ×2) by (2 inches ×2)

= 6 feet by 4 feet

The Area of the room can now be calculated as

Area=( 6 feet × 4 feet)

= 24 ft^2

how much will the new carpet cost?

we know that the carpet costs $4.89 per square foot, then the cost by the area of the room= (Area× $4.89 per square foot)

=24 ft^2 x $4.89

=$ 117.36

Hence, the new carpet cost is $ 117.36

Answer:

Step-by-step explanation:

If you notice very carefully then you will see that the line passes through the points :

( 1 , - 2 )

( - 1 , 2 )

Hence the value of x = 1 when the value of y = - 2 .

We know that - 2 × 1 = - 2

⇒ - 2 x = y

⇒ y = - 2x

Hence the first OPTION is correct .

Verification :

For points ( - 1 , 2 ) we can write :

y = - 2x

⇒ 2 = - 2 × - 1

⇒ 2 = 2

Hence the answer is verified .

Always try to use the converse of the graphical method .

( Nothing converse is there ... just saying the opposite steps of that method :P )

I mean in graphical method we plot points and then join , here identify the joined points and then make the equation .

Need help with middle two questions... I’ll give points

nignag [31]

Answer:

ok sorry i could not put this into a formula im have to go but i will show you a really easy way.

Step-by-step explanation:

for number 1 i got (7,-1)

This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.

The correct way for doing number 1 is using the distance formula i believe but im running out of time

for the second one i got (3, -1/2)

we do this by using the midpoint formula.

The first picture is for number one and the second for number 2

if you have any questions feel free to ask in the comments
