Answer:

-16x - 30

Step-by-step explanation:

4(-3x - 5) - (10 + 4x) = 4*(-3x) - 4*5 + (-1)*10 + (-1)*4x

= -12x - 20 - 10 - 4x {add like terms}

= -12x - 4x - 20 - 10

= -16x - 30

Convert 0.0000.489 to scientific notation

Volgvan

I do not understand why there are two decimal places.
But either ways if you are asking for :
0.0000489 then it is 4.89*10⁻⁵
0.489 then it is 4.89*10⁻¹
The trick is to count the zeroes to the first actual significant number you see and then write the number you counted with a negative sign for your power.
I hope this helps!

Consider the following Function: F(x)= 7x-9 If the output is 26, what is the input?

Wewaii [24]

<h2>Answer:-</h2>

★ Input of the given function F(x) is 5.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Given:-</h3>

✯ F(x) = 7x - 9

✯ Output = 26

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Solution:-</h3>

According to the question the output is 26.

Hence, the above data can be written in an equation form.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ F(x) = 7x - 9 = 26

➪ 7x = 26 + 9

➪ 7x = 35

➪ $\sf x = \dfrac{35}{7}$

➪ $\bold\red{x = 5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, F(x) = 5
