1.901 x 10^-7 in standard notation

WITCHER [35]

Answer:

In standard form, it would be 0.0000001901!

Step-by-step explanation:

As you can see, if the exponent is negative, the answer would be a decimal so moving the decimal place 7 times to the left, that would be your answer.

Determine the average rate of change of f (x) = x² - 10x + 5 over the interval [-4, 4].<br> =<br> -

jeka57 [31]

Answer:

f ( x ) = ( x - 5 ) ² - 20

Step-by-step explanation:

1- Add the same value to both sides

f ( x ) = x ² - 10x + 5

2- Add 25 to the expression

f ( x ) + ? = x ² - 10x + ? + 5

3- Add 25 to the left-hand side

f ( x ) + ? = x ² - 10x + 25 + 5

4- Factor the expression

f ( x ) + 25 = x ² - 10x + 25 + 5

5- Move the constant to the right

f ( x ) + 25 = ( x - 5 ) ² + 5

6- Calculate

f ( x ) = ( x - 5) ² + 5 - 25

It will help me a lot if you count me as brainlist anyways good luck!

Solve the system of equations graphically. Write your answer as an ordered pair (x,y). 6x ‒ 3y = 12 y = x ‒ 2

Sedbober [7]

The answer to the system of equation is (2,0)
6x - 3y = 12 --->> 3y = 6x - 12 -->> y = 2 x -4

y = 2x - 4
y = x - 2

In this case we subtract y = x - 2 from y = 2x - 4
So, it would be
y = 2x - 4
-(y = x - 2) --->> -y = -x +2

y = 2x - 4
-y = -x + 2
---------------
0 = x - 2
Now we add 2 to both sides to isolate x

So, x = 2
Now we replace x for two in both equations.

6(2) - 3y = 12
12 - 3y = 12 (I'm distributing)
-3y = 0
3y = 0
y = 0

Now the other equation

y = 2 -2
y = 0

So, the answer is (2,0)

I hope this helps.
YOU'RE WELCOME :D
