can you find the cube root of a negative number? if so, is it positive or negative? explain your reasoning

Inga [223]

Yes you can and it is negative because if you think about it, the answer to the 3rd power is your original question, so for example, -8 would equal to the answer times itself 3 times
now ask yourself, does 2 times itself 3 times = to -8
or -2 times itself 3 times = to -8

Liam and Sarah have each drawn a line on the scatter plot shown below:

spayn [35]

The answer is B) Line A, because it is closet to most data points.

That is your answer because Line A is the closest to most of the data points, while Line B is more farther away. Also, the line of best fit has nothing to do with the positive or negative association.

Answer:

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10} = \frac{7x - 10}{5}, x \neq -2$

Removable (Holes)
Jump (Piece-wise functions)
Infinite (Asymptotes)

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{7x^2 + 4x - 20}{5x + 10}$

Step 2: Simplify

[Frac - Numerator] Factor quadratic: $\displaystyle \frac{(7x - 10)(x + 2)}{5x + 10}$
[Frac - Denominator] Factor GCF: $\displaystyle \frac{(7x - 10)(x + 2)}{5(x + 2)}$
[Frac] Divide/Simplify: $\displaystyle \frac{(7x - 10)}{5}, x \neq -2$

When we divide (x + 2), we would have a removable discontinuity. If we were to graph the original function, we would see at x = -2 there would be a hole in the graph.

How would 2X + Y = 13 be written

o-na [289]

Answer:

y = -2x+13

Step-by-step explanation:

2X + Y = 13

The slope intercept form is y = mx+b where m is the slope and b is the y intercept

Subtract 2x from each side

2x-2x+y = -2x+13

y = -2x+13
