Basically what you do is                             (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = <span>815000000000000000000</span>

50 POINTS AND BRAINIEST PLEASE HELP
exis [7]

Answer:

<h2><u>y = -2x</u></h2>

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 .

x = 130 is your answer

130 - 20 = 110

Since line E and F are parallel and are straight lines, we know both angles will add up to 180°

110 + 70 = 180
