What’s the square root of -121

1 answer:

5 0

The answer is 11 i

Explanation:

The square root needs to be a number that can be multiplied by itself and equal the original number.

In this case, the number is 11, 11*11 = 121

However, you are looking for the square root of a negative number, due to this you would add i to the answer,
i = imaginary number, or -

( Depending on your grade/ teacher however, you can put "no solution"

Write the product in standard form. ( 9 + 5i)( 9 + 8i)

disa [49]

( 9 + 5i)( 9 + 8i)
= 9(9+8i)+5i(9+8i)
= 81+72i+45i+40i^2
= 81+117i+40(-1)
= 81-40+117i
= 41+117i. Answer

Zara is serving a fresh pie. She starts by cutting the pit in half, and then cuts each half into 4 equal pieces. What fraction o

Reptile [31]

C.

If each 1/2 is cut in 4 than you would have to multiply that by 2 because it's only half. Then since you're finding what fraction is it you would put a 1 on top and say 1/8.

Put this into Slope Intercept Form x + 6y = –6

mel-nik [20]

Answer:

$y=-\frac{x}{6} -1$

Step-by-step explanation:

Hi there!

We are given the following equation:
x+6y=-6

And we want to convert it into slope-intercept form

Slope-intercept form is known as y=mx+b, where m is the slope and b is the y intercept

The equation is currently in standard form, which is ax+by=c, where a, b, and c are integer coefficients

Notice how in standard form, both the terms that contain x and y are on one side, but in slope-intercept form, y is by itself on one side

So essentially, in order to convert from standard form to slope-intercept form, we need to solve for y

Here is our equation again:

x+6y=-6

Start by subtracting x from both sides

x+6y=-6

-x -x

_______________

6y=-x-6

Now divide both sides by 6

$y=-\frac{x}{6} -\frac{6}{6}$
We can simplify the fractions to become:

$y=-\frac{x}{6} -1$
Hope this helps!
