Equation for the points (3,8) (2,6) on slope

Answers

(8-6)/(3-2) = (2)/(1)=4

The slope is 2

y=2x + b

Plug in a point to solve for b
8 = 2(3) + b

8 = 6 + b
b = 2

The equation is y = 2x + 2

Almost all nonmetals are very poor conductors of electricity but there is one There is One that is a pretty good conductor which one is it Xenon corban Iodine nitrogen

Answers

Answer:

Carbon

Step-by-step explanation:

Carbon is a non metal but Graphite is a pretty  good conductor of electricity which is an allotrope of Carbon. There are delocalised electrons which are free. These are responsible for conduction.

These arise because each carbon atom is only bonded to 3 other carbon atoms. The structure of Graphite provides for this arrangement. This leaves 1 electron to become delocalised.

Thus Graphite can be used for  electrodes in batteries and for electrolysis.

​ of an hour. Ben drinks tea at a constant rate.
How many liters of tea does he drink in one hour?

Answers

Answer:

5(1)/(4) liters of tea does he drink in one hour.

Step-by-step explanation:

Unit rate defined as the rate are expressed as a quantity 1 such as 2 miles per hour or 4 meter per second.

As per the statement:

Ben drink 3(1)/(2) = (7)/(2) liters of tea every (2)/(3) of an hour.

We have to find the liters of tea does he drink in one hour.

\text{Unit rate per hour} = ((7)/(2) )/((2)/(3)) = (7)/(2) * (3)/(2) =(21)/(4) = 5(1)/(4) liters

Therefore, 5(1)/(4) liters of tea does he drink in one hour.

Square A and rectangle B have the same width. The length of rectangle B is 4 cm greater than its width. The area of rectangle B is 20 cm greater than the area of square ASet up an equation and solve it to find the area of square A.

-Thanks! :D

Answers

Noting that square A is a square, this is what we have:
A = B
A^2 = B x (B + 4) + 20

I can try subbing in A to B
since A = B:

A^2 = A x (A + 4) + 20
20 = A^2 - (A x (A + 4))
20 = A^2 - (A^2 + 4A)
20 = 4A
A = 5

By the way, A is width of square A and B is the width of rectangle B in my solution,
