Answer:

It would be C

Step-by-step explanation:

The number is between integers, so it can't be an integer or a whole number. It's written as a ratio of two integers, so it's a rational number and not irrational.

Solve 9(x-11)=9 please help

Sedbober [7]

Answer: 12

Step-by-step explanation:

Distribute the 9(x-11) first. If you distribute it, it becomes 9x-99

9x-99=9

Add 99 to both sides

9x=108

Divide by 9 on both sides

X=12

A function is shown: f(x) = 36x2 − 1.

german

Answer:

The equivalent function: $f(x)=(6x+1)(6x-1)$

Step-by-step explanation:

The x-intercepts of the given function on the graph can be obtained by equating the function to zero.

This is because on the x-axis, the y-coordinate is zero.

$36x^{2} -1=0\\36x^{2} =1\\x=\frac{1}{6},-\frac{1}{6}$

The function that has the same x-intercepts on the graph from the given options is:

$f(x)=(6x+1)(6x-1)$

Alternate Method:

The answer can also be obtained by factorizing the question.

What is the value of i 75 ? − 1 − − 1 − i − − i 1 1 i

SIZIF [17.4K]

-i

The best way to explain this is to divide 75 by 4 and whatever remainder you have (in this case 3) you make it i^3 which is -i
